The Mid-County Expressway passes through suburban areas, while the Northeast Extension predominantly runs through rural areas of mountains, forest, and farmland, with development closer to Philadelphia and in the Lehigh Valley and the Wyoming Valley. I-476 intersects many major roads, including I-76 (Schuylkill Expressway) inWest Conshohocken,I-276(Pennsylvania Turnpike) inPlymouth Meeting,U.S. Route 22(US 22) nearAllentown,andI-80nearHickory Run State Park.

At its opening in 1979, I-476 was a three-mile-long (4.8 km), four-lane spur expressway connecting the Schuylkill Expressway with Chemical Road in Plymouth Meeting. The highway expanded the capacity for travel betweenKing of Prussia,the Schuylkill Expressway, thePhiladelphia Main Line,andPhiladelphiasuburbs to the city's north and inSouth Jersey.The highway was initially planned to connect down to I-95 in Delaware County. This portion of the highway opened in 1991.

In 1996, the I-476 designation was affixed to the preexisting Northeast Extension of the Pennsylvania Turnpike, replacingPennsylvania Route 9(PA 9). This was an older four-lane pre-Interstate limited-access highway that opened in sections between 1955 and 1957. Of earlier design, its cross section was very narrow, with only 4 feet (1.2 m) between opposing lanes of traffic in places. This extended I-476 north of Plymouth Meeting toClarks Summit(near Scranton) as a part of the Pennsylvania Turnpike system. I-476 connected to the Northeast Extension at a state-of-the-art three-level interchange. This provided direct access to both I-276 east and I-476 north, now on the Northeast Extension.

With the redesignation of the Northeast Extension, I-476 surpassedI-495inMassachusettsas the nation's longest auxiliary Interstate Highway. I-476 was widened to six lanes from the Mid-County Interchange to south ofQuakertownbetween 2011 and 2020.

Route description

Woodlyn to Plymouth Meeting

edit
I-476 southbound pastPA 3inBroomall

The portion of I-476 betweenI-95and thePennsylvania Turnpike(I-276) runs north–south throughDelawareandMontgomerycounties and is officially known as the Mid-County Expressway and the Veterans Memorial Highway, as well as by the nickname the "Blue Route". The road's southern terminus is at adirectional T interchangewith I-95 nearChester,southwest ofPhiladelphiain Delaware County, nearPhiladelphia International Airport.[4]

Heading north, the road passes underCSX'sPhiladelphia Subdivisionrail line and has an interchange with MacDade Boulevard inWoodlyn,where it narrows to a four-laneparkwaythat runs parallel to theCrum Creek.It winds through the western Philadelphia suburbs ofWallingfordandSwarthmore,where I-476 passes underSEPTA'sMedia/Wawa Lineand comes to adiamond interchangewithBaltimore Pikejust west ofSpringfield.From here, the freeway crosses over SEPTA's light railMedia–Sharon Hill Lineand continues north to Springfield, where it meetsUS 1at athree-level diamond interchange.[4]

Past US 1, the parallel Crum Creek splits to the northwest and I-476 continues through wooded suburban areas. Along this stretch, the road briefly gains a southboundtruck lane.The freeway comes to apartial cloverleaf interchangewithPA 3inBroomall,where it widens to six lanes.[4]The route continues toRadnor Township,which is part of thePhiladelphia Main Linesuburbs, reaching an interchange withUS 30west ofVillanova.[4]Stone monuments, including a large stonecairnatop a hill and a large crushed-stone image of a mythologicalgriffinon a hillside, were constructed at the US 30 interchange to commemorate Radnor's history as part of theWelsh Tract.[5]Proceeding northward, the road passes over SEPTA'sNorristown High Speed Linebefore it crosses underAmtrak'sKeystone Corridorrail line.

The route enters Montgomery County and comes to an interchange withI-76(Schuylkill Expressway) inWest Conshohockenthat also has access toPA 23.After crossing overNorfolk Southern'sHarrisburg Line,theSchuylkill River,SEPTA'sManayunk/Norristown Line,and theSchuylkill River Trailon thePearl Harbor Memorial Bridge,the freeway heads intoPlymouth Township.In Plymouth Township, the route has interchanges withRidge Pikeand Chemical Road before passing over Norfolk Southern'sMorrisville Lineand reaching an interchange servingGermantown Pikeand Plymouth Road inPlymouth Meeting.[4][6]The entire length of the Blue Route is designated the Blue Route Scenic Byway, aPennsylvania Scenic Byway.[7]

In Plymouth Meeting, I-476 comes to the Mid-County Interchange, where it enters thePennsylvania Turnpikesystem and has a mainline toll plaza before coming to an interchange withI-276,which follows the mainline of the Pennsylvania Turnpike, heading north from here as the six-lane Northeast Extension of the Pennsylvania Turnpike. The route continues through the Philadelphia suburbs, passing over CSX'sStony Creek Branchrail line, and reaches an interchange withPA 63west ofLansdalethat serves theNorth Penn Valleyregion. Past this interchange, the route enters a more rural setting of woods and farms, narrowing to four lanes before crossing intoBucks Countyand coming to an interchange withPA 663west ofQuakertown.The Northeast Extension continues northwest intoLehigh County,part of theLehigh Valleymetropolitan area, past the PA 663 interchange. The road passes overNorfolk Southern'sReading Line.The route has ramps to the dual-access Allentown Service Plaza inUpper Macungie Township,and, just north of it, I-476 reaches an interchange withUS 22(Lehigh Valley Thruway) west ofAllentown,which offers an indirect connection toI-78andPA 309.[4]

North of Allentown, the route crosses under Norfolk Southern'sCatasauqua and Fogelsville Railroadline and runs through farmland with some development. The road passes underBlue Mountainin theLehigh Tunneland entersCarbon Countyin thePocono Mountainsregion. Here, I-476 crosses over theLehigh Riverand Norfolk Southern'sLehigh Linebefore it has an interchange withUS 209east ofLehighton.Continuing through mountainous areas, the route has ramps to the dual-access Hickory Run Service Plaza prior to coming to a diamond interchange withPA 903.Past here, I-476 cuts throughHickory Run State Parkbefore reaching an interchange withPA 940providing a connection toI-80just to the north of the state park.[4]

The route continues through mountainous terrain, heading intoLuzerne Countyat a crossing of the Lehigh River and coming to an interchange withPA 115inBear Creekthat provides access to nearbyWilkes-Barre.[4]The route comes to a mainline toll plaza nearPittstonthat marks the northern end of the closed toll system along the Northeast Extension.[4][9]

A short distance later, an interchange withPA 315provides indirect access toI-81andScranton.[4]Past this interchange, I-476 crosses under aLuzerne and Susquehanna Railwayline before it entersLackawanna County.Here, the route has a bridge over a Luzerne and Susquehanna Railway line and heads through built-up areas of theWyoming Valleyas it skirts around Scranton, passing under I-81 before coming to a bridge over Norfolk Southern'sSunbury Line,theLackawanna River,and aReading Blue Mountain and Northern Railroadline. I-476 reaches a mainline all-electronic toll plaza and an exit to Keyser Avenue inTaylor.

North of Scranton inClarks Summit,the route crosses a valley on the 1,630-foot-long (500 m), 163-foot-high (50 m) John E. Fitzgerald Memorial Bridge,[10]passing over Norfolk Southern's Sunbury Line,US 6/US 11,andPA 407.Past the bridge, I-476 comes to ahairpin curveand reaches a mainline all-electronic toll plaza before it ends at an interchange with connections to I-81, US 6, and US 11. US 6 joins the turnpike for less than 0.25 miles (0.40 km) to connect between I-81 and US 11. As this is beyond the Clarks Summit toll plaza, no toll is collected on this short segment.[6]

Tolls

edit
The Mid-County mainline toll plaza, which marks the southern terminus of the Northeast Extension, before conversion to all-electronic tolling

The Northeast Extension of thePennsylvania Turnpikeusesall-electronic tolling,with tolls payable bytoll by plate,which usesautomatic license plate recognitionto take a photo of the vehicle's license plate and mail a bill to the vehicle owner, orE-ZPass.Tolls along the section between the Mid-County and Wyoming Valley toll plazas, along with the mainline Pennsylvania Turnpike between Warrendale and Neshaminy Falls, are based on distance traveled. Mainline toll plazas are also located at Keyser Avenue and Clarks Summit, charging a flat rate using toll by plate or E-ZPass.

There are no tolls on exit ramps between Wyoming Valley and Clarks Summit. As of 2024,it costs a passenger vehicle $26.20 to travel the length of the Northeast Extension between Mid-County and Wyoming Valley using toll by plate and $12.80 using E-ZPass. The Keyser Avenue and Clarks Summit toll plazas cost $3.20 using toll by plate and $1.50 using E-ZPass for passenger vehicles.[11]

Until March 2020, the road used theticket systemmethod of tolling between the Mid-County and Wyoming Valley toll plazas along with the mainline Pennsylvania Turnpike between Warrendale and Neshaminy Falls.[12]With the ticket system, a motorist received a ticket upon entering the turnpike at an interchange and paid the fare and surrendered the ticket upon exiting. If a motorist lost the ticket, the turnpike charged the highest fare to the exit where the motorist left.[13]Cash, credit cards, and E-ZPass were accepted at traditional toll plazas.[12]

In March 2020, as a result of theCOVID-19 pandemic,[14]the all-electronic tolling system on the turnpike will initially use existing toll booths at exits, along with existing equipment at all-electronic tolling interchanges, until mainline toll gantries between interchanges are constructed.[15]Mainline toll gantries are planned to be in operation by 2025.[16][17]

On April 29, 2018, the turnpike commission implemented all-electronic tolling at the Keyser Avenue and Clarks Summit toll plazas.[18][19]All-electronic tolling was originally scheduled to be implemented on the entire length of the Northeast Extension in the later part of 2021.[15]

Services

edit

Emergency assistance and information

edit

The Northeast Extension formerly had acall boxevery mile (1.6 km) for its entire length.[20]In September 2017, the turnpike commission began removing the call boxes due to increased mobile phone usage making the call boxes obsolete.[21]Motorists may also dial *11 on their mobile phones. First responder services are available to all turnpike customers via theGEICOSafety Patrol program. The safety patrol program, which is free, looks for disabled motorists, debris, and accidents along the roadway and provides assistance. The patrol service is available 24 hours every day of the year. Each patrol vehicle covers a 20-to-25-mile (32 to 40 km) stretch of the turnpike.[22][23]Towing services are available from authorized service garages located near the highway.[24]Pennsylvania State PoliceTroop T patrols the Pennsylvania Turnpike Northeast Extension. It has headquarters inHighspire(along the mainline turnpike) and a substation along the Northeast Extension at Pocono.[25]

ThePennsylvania Turnpike Commission(PTC) broadcasts current roadway, traffic, and weather conditions viahighway advisory radiotransmitters at each exit. Broadcasts are available on 1640 kHz AM and can be received approximately two miles (3.2 km) away from each exit.[26]The511PAtravel information service provides alerts, an interactive map, weather information, andtraffic camerasto motorists. There arevariable-message signslocated along the roadway that provide information to motorists such as accidents, construction, weather, and traffic congestion.[27]

Service plazas

edit
TheAllentownservice plaza

The Northeast Extension of the Pennsylvania Turnpike has twoservice plazasat Allentown and Hickory Run, which are accessible by both northbound and southbound traffic. The service plazas offer multiplefast-food restaurants,aSunocogas station, and a7-Elevenconvenience store. Other amenities are available such as an ATM, E-ZPass sales, free cellphone charging,Pennsylvania Lotterysales, picnic areas, restrooms, tourist information, Travel Board information centers, and Wi-Fi. The Allentown plaza contains a seasonalfarmers' market.Both plazas offer conventionalgasolineanddiesel fuel.The Sunoco and 7-Eleven locations are operated by 7-Eleven itself while the restaurants and general upkeep of the service plazas are operated byApplegreen.[28]

In 2006,HMSHostwas awarded a contract to reconstruct the service plazas along the turnpike.[29]The reconstruction of the service plazas, which was to cost more than $150 million (equivalent to $218 million in 2023[30]), included afood courtlayout and modernized restrooms. The Allentown service plaza was rebuilt between September 2007 and May 2008 while the Hickory Run service plaza was rebuilt between January 2009 and November 2010.[31]

The Art Sparks program was launched in 2017 as a partnership between the turnpike commission and thePennsylvania Council on the Artsto installpublic artcreated by local students in the Arts in Education residency program in service plazas along the turnpike over the next five years. The public art consists of amuralreflecting the area where the service plaza is located.[32][33]

A stretch of the Mid-County Expressway near the now-closedHaverford State Hospitalin the early 1970s; the stretch was completed in the early 1990s.

Originally planned as far back as 1929, the Mid-County Expressway was later proposed by thePennsylvania Turnpike Commissionas the "Chester Extension" of the Pennsylvania Turnpike in 1954. After the advent of theInterstate Highway System,the project was transferred to thePennsylvania Department of Highwaysto be built as part of the system, designating it first asInterstate 495(I-495) and later asInterstate 480(I-480), as I-76 was designated asI-80Sat the time. The present-day I-476 designation was assigned on February 6, 1964, when I-80S was renumbered as I-76.[34]

The road received its nickname from a 1958 location report indicating various proposed geographic configurations of an expressway throughDelaware Countywith lines of various colors on a map. The "blue route" through theCrum Creekvalley won out over other contenders, which included a more easterly "red route" and "yellow route" and a more westerly "green route".[35]

As one of the most controversial Interstate Highways in Pennsylvania, construction of I-476 began in 1967 but would take decades to build due to litigation between thePennsylvania Department of Transportation(PennDOT) and several communities in the road's path over environmental concerns. Two sections of the road in Radnor Township and inLower Merion Townshipwere built in 1970 but remained closed to traffic as they did not connect to any other roads. The section of I-476 between I-76 and Chemical Road opened to traffic in 1979 while the section between I-95 and MacDade Boulevard opened to traffic in August 1988. The road opened between Chemical Road and Plymouth Road in August 1991 while the final section of I-476 between MacDade Boulevard and I-76 was opened in December 1991.[35]

An agreement in 1985 led to many environmental compromises in the road's design, including a downsized four-lane design south of PA 3 (although a part of the span between exits 9 and 5 has a third truck lane on the southbound side),ramp meters,and scenic route status, prohibiting the erection of advertisement billboards along the entire freeway portion. The Radnor Gateway Enhancement Strategy was implemented to install large scale sculpture elements by artistWilliam P. Reimann,most notably the stone griffin and cairn at exit 13.[36]While the redesigned highway was largely well-received, the constriction to four lanes has led to bottleneck conditions in the area, and many communities that originally opposed the road have now called for its widening.[37]The Philadelphia Inquirerdubbed I-476 "the most costly, most bitterly opposed highway in Pennsylvania history" due to the decades of opposition it garnered.[38]

I-476 northbound at PA 3 in Broomall

Plans to build an interchange connecting I-476 (Mid-County Expressway) to the Pennsylvania Turnpike were made; the turnpike commission approved a contract to build the interchange in March 1989.[39]That June, a losing bidder decided to challenge the turnpike commission, saying it violated female and minority contracting rules regarding the percentage of these employees that were used for the project. Under this rule, bidders were supposed to have at least 12 percent of contracts to minority-owned companies and at least four percent to female-owned companies. The losing bidder had 12.4 percent of the contracts to minority companies and 4.2 percent to female-owned companies while the winning bidder had 6.1 percent and 3.7 percent respectively. The turnpike commission decided to rebid the contract but was sued by the original contractor. This dispute delayed the construction of the interchange.[40]The contract was rebid in November 1989 after theSupreme Court of Pennsylvaniapermitted it.[41]The interchange between I-476 and the turnpike mainline was completed in November 1992; the ramps to the Northeast Extension opened a month later.[42][43]An official ribbon-cutting took place on December 15, 1992.[44]

In the 2000s, the road underwent a rehabilitation project, including paving, bridge repair, and ramp maintenance of the entire length of the freeway between I-95 and the Pennsylvania Turnpike. The section between I-95 and PA 3 was repaved in 2005 while the section between PA 3 and I-76 was repaved in 2007.[45]The section between I-76 and I-276, which was completely reconstructed, was finished in the end of 2011.[46]

PennDOT has plans to improve I-476 to reduce traffic congestion. Smart technology will be added to detect traffic congestion. The first phase will addvariable speed limitsthat can change based on weather and congestion, new ramp meters, and electronic signs. The left shoulders of the roadway between I-95 and PA 3 will be widened and used as a third travel lane during peak traffic periods. Construction on the smart technology is underway while construction of the third lane is expected to begin in 2026. This improvement project is planned to be completed in 2030.[47]

Northeast Extension

edit
Pennsylvania Route 9
LocationPlymouth Meeting–Clarks Summit
Length111.04 mi[8](178.70 km)
Existed1974–1996

In 1953, an extension of the Pennsylvania Turnpike from the mainline near Plymouth Meeting north throughNortheastern Pennsylvaniato theNew Yorkstate line nearBinghamton, New York,was proposed.[48][49]Groundbreaking for the Northeastern Extension occurred on March 25, 1954, inWhite Haven,with GovernorJohn S. Fineand commission chair Thomas J. Evans present. The Northeast Extension was planned to run from the mainline Pennsylvania Turnpike in Plymouth Meeting north to a temporary terminus at Scranton.[50]In April 1954, $233 million (equivalent to $2.1 billion in 2023[30]) in bonds were issued to build the Northeastern Extension along with theDelaware River–Turnpike Toll Bridgeon the mainline Pennsylvania Turnpike.[51]

The Northeast Extension was built with a four-foot (1.2 m) median in order to save money.[52]Due to the mountainous terrain it passed through, a large amount of earthwork was necessary to build the road along with the construction of large bridges.[53]Among the bridges built was the 1,630-foot-long (500 m) Clarks Summit Bridge (since renamed for John J. Fitzgerald, Turnpike engineer and superintendent) over US 6/US 11, which at the time was the tallest bridge on the Pennsylvania Turnpike system at 135 feet (41 m).[10][54]The Northeast Extension also included the two-lane Lehigh Tunnel under Blue Mountain. The tunnel was originally going to be named for commission chair Evans but was changed when he was convicted of conspiracy to defraud the commission of $19 million (equivalent to $133 million in 2023[30]).[53]

The roadway opened between Plymouth Meeting and the Lehigh Valley interchange near Allentown on November 23, 1955. The highway was extended north to a temporary interchange atEmeraldon December 28 of that year.[55]The Northeast Extension was opened between Emerald and Wyoming Valley on April 1, 1957.[56]The entire length of the Northeast Extension was finished on November 7, 1957, with the completion of the northernmost part between Wyoming Valley and Scranton.[57]The part of the Northeast Extension between Scranton and the New York state line was not built as part of the Pennsylvania Turnpike system but rather the Interstate Highway System as I-81.[58][59]At the northern terminus, the Northeast Extension narrowed to two lanes along the northbound offramp at Scranton to come to its northern terminus, with an abandoned short spur of the mainline heading north. A pair oftrumpet interchangeswere built to connect the Northeast Extension and I-81.[59]

On April 14, 1969, a project which deconstructed the grass median and replaced it with a metallic jersey barrier was completed.[60]

In 1974, the roadway was designated PA 9.[61][62][63]

The tickets along the Northeast Extension of the Pennsylvania Turnpike were originally handed out by person. In 1987, machines started to replace humans in distributing tickets.[64]

Lehigh Tunnelsouthbound

When it first opened, traffic on the Northeast Extension of the Pennsylvania Turnpike was light.[52]By the 1970s, traffic along the roadway increased with the completion of the connecting I-80 and the rising popularity of the Pocono Mountains as a vacation destination. As a result, the two-lane Lehigh Tunnel faced serious congestion. Plans were made to either bypass the tunnel or add a second tube. The turnpike commission decided it would build a second tunnel as the cost was lower than building a bypass.[65]In 1988, a $37-million (equivalent to $82.3 million in 2023[30]) contract was awarded to build the second tube.[66]Groundbreaking for the tunnel took place on February 14, 1989, with GovernorRobert P. Caseyin attendance.[67]

Excavation of the new tunnel began in July of that year. Construction of the second tube utilized theNew Austrian tunneling method,which reduced the cost of the tunnel by $5 million to $6 million (equivalent to $11.1 million to $13.3 million in 2023[30]). It was the first tunnel in the US to use this construction method. The second tube at Lehigh Tunnel opened on November 22, 1991, with Governor Casey in attendance leading a line of antique cars. Construction of the tunnel cost $45 million (equivalent to $89.8 million in 2023[30]). The new tube is used for southbound traffic while the original tube carries northbound traffic. The newer tunnel is wider, higher, and brighter than the original.[68]

On February 1, 1995, the Keyser Avenue interchange near Scranton was opened at a cost of $22.4 million (equivalent to $40.9 million in 2023[30]). Construction of this interchange also involved constructing a new mainline flat-rate toll barrier near the new interchange.[69]

On November 1, 1996, the Northeast Extension was added to the Interstate Highway System as a northern extension of I-476, replacing the PA 9 designation along the road. The addition of the second tube at the Lehigh Tunnel along with new guardrails and line striping was necessary for the toll road to become an Interstate. It was hoped that the Interstate designation would bring economic development and tourism to the areas served by the roadway.[70]This extension resulted in I-476 surpassing the 120-mile (190 km)I-495inMassachusettsas the longest auxiliary Interstate Highway,[71]though it could be contested for this title in the future byI-369inTexas.

In 1990, anelectronic toll collectionsystem was proposed for the Pennsylvania Turnpike, where a motorist would create an account and use an electronic device that would be read from an electronic tollbooth. The motorist would be billed later.[72]The multi-state electronic tolling system, which was to be called E-ZPass, was planned to be implemented by 1998.[73][74]The planned installation date was later pushed back to 2000.[75]On December 2, 2000, E-ZPass debuted along the Northeast Extension of the Pennsylvania Turnpike between Mid-County and Lehigh Valley.[76][77]On December 15, 2001, E-ZPass was extended to include the entire length of the Northeast Extension of the Pennsylvania Turnpike.[78][79]Commercial vehicles were allowed to start using E-ZPass on December 14, 2002.[80]

On November 24, 2004, the day beforeThanksgiving,2,000Teamsters Unionemployees went onstrike,after contract negotiations failed. This was the first strike in the history of the roadway. As this is usually one of the busiest traffic days in the US, to avoid traffic jams, tolls were waived for the rest of the day.[81]Starting on November 25, turnpike management personnel collected flat-rate passenger tolls of $2 and commercial tolls of $15 from cash customers on the ticketed system, while E-ZPass customers were charged the lesser of the actual toll or the same flat rates.[82]The strike ended after seven days when both sides reached an agreement on November 30, 2004. Normal toll collection resumed December 1, 2004.[83]

I-476 North inWhitpain Township

In 2007, the turnpike commission announced plans to widen the Northeast Extension to six lanes between Mid-County and Lansdale.[84]The project divided this stretch of highway into two sections. Work on the southern section began in January 2008 with the replacement of two bridges over the Northeast Extension to accommodate the widened highway. Construction on the actual widening phase commenced in January 2011. Completion was originally planned in 2013; however, construction fell a year behind schedule.[85][86]

Construction on widening the northern section started in May 2014, while work on widening the southern section finished up in October of that year. By this point, the project scope was expanded to include the Lansdale interchange itself, the roadway to a point one mile (1.6 km) north of the interchange, and two new E-ZPass-only ramps at the Lansdale interchange to relieve congestion at the toll plaza. This new northbound exit ramp opened December 4, 2016, and the companion southbound onramp opened a week later.[87]Construction along the northern section was originally planned to finish by the end of 2016 but was delayed until mid-2017.[88]Construction was substantially completed, with all six lanes open, by August 31, 2017.[89]

Once widening was completed from Mid-County to Lansdale, a similar project began on the next segment of highway, from Lansdale to Quakertown. As done on the first project, the Lansdale–Quakertown segment was rebuilt in two sections, with a southern half started in late 2017, widening the road to six lanes with full shoulders.[85]Advance work began in early 2013 with replacement of several bridges in this area north of Lansdale, with work on the actual widening beginning in late 2017.[90]Widening of this section was completed in late 2020.[91]In April 2022, construction began on widening the northern section of the roadway between Lansdale and Quakertown, with completion expected in early 2025.[92]

The turnpike commission has stated its intention of continuing the widening effort past Quakertown all the way north to the Lehigh Valley interchange at milepost 56,[93]although it will take until the late 2020s to get it done.

In 1990, plans were made to build an interchange at PA 903 in Carbon County. A bill authorizing construction of this interchange was signed into law by Governor Casey in July of that year.[94]Plans for this interchange were cancelled by the turnpike commission in 1995.[95]In 2006, plans for an interchange at PA 903 were resurrected, with the proposed interchange to be all-electronic, in that it will only accept E-ZPass.[96]Construction on the $23-million (equivalent to $32 million in 2023[30]) interchange began in the middle of 2008.[97][98]The interchange opened to traffic on June 30, 2015.[99]

On April 28, 2016, plans were announced for a "Scranton Beltway" to use I-476 as a bypass for I-81 around the heavily congested segment through Scranton and its suburbs. The turnpike between the two I-81 interchanges carries an average of 10,000 vehicles per day vs. 70,000 on the parallel segment of I-81. This project will build two high-speed connections between I-476 and I-81: one south of Scranton inDupontand one north of Scranton inSouth Abington Township.Tolls on the connections will be paid with E-ZPass or toll by plate. Construction of this project is expected to cost $160 million.[100]In 2021, design work on the project resumed, with construction expected to begin in 2025.[101]

On February 21, 2018, Howard M. Sexton, a 70-year-old truck driver fromNew Jersey,was killed in the southbound Lehigh Tunnel, when an electrical conduit broke free from the tunnel's ceiling and fell through the windshield of his truck, striking him in the head.[102]In a preliminary report issued on May 1, 2018, theNational Transportation Safety Boardrevealed that a 10-foot-long (3.0 m) section of conduit fell into the path of Sexton's truck after the steel support system for the conduits, which were suspended from the apex of the tunnel arch directly over the travel lanes, failed. The tunnel had last been inspected in 2016, at which time an inspector found evidence of corrosion on several of the steel support straps.[103]

In late 2021, construction began to replace the functionally obsolete Hawk Falls Bridge that carries I-476 over Mud Run in Carbon County. The replacement bridge will be a 720 feet (220 m) long steel bridge that will include shoulders. Construction of the replacement bridge is expected to be completed in the middle part of 2026.[104]

Exit list

edit

The old exit numbers (31 and upward) on the Northeast Extension were a continuation of old exit numbers 1 through 30 on the east–west turnpike. On the east–west turnpike, the interchange with I-476 was old exit 25A because it was between old exits 25 and 26 on the east–west turnpike.
