Interstate 395(I-395) is anauxiliary Interstate Highwayin the U.S. states of Connecticut and Massachusetts; it is maintained by theConnecticut Department of Transportation(CTDOT) and theMassachusetts Department of Transportation(MassDOT). Spanning nearly 67 miles (108 km) on a south–north axis, it is the onlyspur routeofI-95in Connecticut. The 36-mile (58 km) section between its splits from I-95 inEast LymeandSR 695inPlainfieldis a component highway of theConnecticut Turnpike.Within that state, the highway is named theAmerican Ex-Prisoner of War Memorial Highwayfrom Plainfield toThompson.

The highway was first established as part of the Connecticut Turnpike in 1958, while the Connecticut Route 52 designation was applied to the portion north of the turnpike in 1967. Connecticut Route 52 was intended to become a southern extension ofI-290,although the current designation of I-395 was ultimately assigned in 1983.

I-395 begins at theEast Lyme–Waterfordtown line as the Connecticut Turnpike leavesI-95as the latter route turns more easterly towardNew London.It is a relatively rural Interstate for most of its length. It passes through Waterford intoMontvillewhere it meetsRoute 2Aat exit 9. Eastbound Route 2A provides access to theMohegan Suncasino, while westbound Route 2Aruns concurrentlywith I-395 intoNorwichand ends at exit 13, where it terminates as it joins its parent route,Route 2.After passing Route 2, I-395 bends to the east, and continues intoLisbon,Griswold,andPlainfield,where it bends more northerly and parallelsRoute 12for most of the rest of its length. At the Plainfleld–Killinglytown line, the Connecticut Turnpike splits to the east asSR 695,providing access toU.S. Route 6(US 6) at theRhode Islandstate line. I-395 continues north and meets US 6 in Killingly. After crossing intoPutnam,it has an interchange withUS 44.It then passes throughThompsonbefore crossing theMassachusettsstate line intoWebster.

Massachusetts

After passing through Webster andOxford,it entersAuburnwhere it has an interchange withUS 20,which provides access to theRoute 146expressway. The I-395 designation for the highway ends as it meetsI-90(Massachusetts Turnpike) at exits 11A and 11B and becomesI-290as it heads towardWorcester,although the mileage for I-395 runs in parallel with its I-290 counterpart until it reachesI-495inMarlborough.It should also be noted that I-395 does not connect directly connect to the Mass Pike, but instead requiresRoute 12southbound for access at exit 12 (formerly exit 7), with traffic passing through at least onetraffic lightcrossing.

Service plazas

In Connecticut, there are three service plazas (a legacy of the turnpike) that provide 24-hour gas stations, convenience stores, plus aSubwayandDunkin' Donuts.

• Montville (milepost 8): It is southbound only between exits 9 and 6.
• Plainfield (milepost 35): It is northbound and southbound between exits 32 and 35.

The Connecticut State Police Troop E barracks occupies the former service plaza on the northbound side at Montville.

History

I-95 at the I-395 split inEast Lyme/Waterfordtown line.

The highway that is now I-395 from its southern terminus withI-95in East Lyme to exit 35 in Plainfield opened on January 2, 1958, as part of the 129-mile (208 km)Connecticut TurnpikefromGreenwichat the New York state line toKillinglyat the Rhode Island state line. In 1964, work began on a freeway extension beyond the turnpike in Plainfield north towardWorcester,connecting to theMassachusetts Turnpike(I-90). This new freeway, as well as the existing section of the Connecticut Turnpike from East Lyme to Plainfield, would be designated as Connecticut Route 52. The section between Plainfield andUS 44nearPutnamopened in 1967, and the section from US 44 to the Massachusetts state line opened in 1969. Massachusetts completed its section of the freeway in 1977.

In 1983, in response to the cancelation of the proposedI-84extension fromHartfordtoProvidence,CTDOTwished to supplement the state's loss of Interstate mileage by applying an Interstate designation to Connecticut Route 52. Initially,I-290was to be extended from its southern terminus inAuburn, Massachusetts.However, in 1983, it was decided to instead apply the I-395 designation to the freeway south of I-90.

In May 2013, CTDOT announced that a project that would begin in early 2014 that included renumbering exits along its section of I-395, andConnecticut Route 2Afrom the then-currentsequential numbering systemto adistance-based schemeto conform with federal exit numbering standards. During the transition, old exit numbers were posted atop the new exit numbers through 2017 to lessen any confusion.The renumbering began on June 24, 2015, and ended in January 2016; the project included renumbering one sign in Massachusetts announcing the first southbound Connecticut exit.

Exit list

Exit numbers were changed from sequential to distance-based numbering in Connecticut between July and December 2015. Along with Connecticut Route 2A, these are Connecticut's initial distance-based exit numbers.MassDOT also planned to switch exit numbers on all of its Interstates, including I-395, to distance-based numbering in 2016. But the contract to change exit numbers which was to be awarded in December 2015 was indefinitely postponed in the middle of 2016. It was not until November 18, 2019, that MassDOT confirmed that beginning in late summer 2020 the exit renumbering project will begin. On July 29, 2021, MassDOT announced that the exit renumbering on I-395 and I-290 will start on August 8, and it will last for two weeks.
