"US 1" redirects here. For other uses, seeUS 1 (disambiguation).

U.S. Route 1orU.S. Highway 1(US 1) is a major north–southUnited States Numbered Highwaythat serves theEast Coast of the United States.It runs 2,370 miles (3,810 km) fromKey West,Florida,north toFort Kent, Maine,at theCanadian border,making it the longest north–south road in the United States.[2]US 1 is generally paralleled byInterstate 95(I-95), though US 1 is significantly farther west and inland betweenJacksonville, Florida,andPetersburg, Virginia,while I-95 is closer to the coastline. In contrast, US 1 in Maine is much closer to the coast than I-95, which runs farther inland than US 1. The route connects most of the major cities of theEast Coastfrom theSoutheastern United StatestoNew England,includingMiami,Jacksonville,Augusta,Raleigh,Richmond,Washington, D.C.,Baltimore,Philadelphia,Newark,New York City,New Haven,Providence,Boston,andPortland.

While US 1 is generally the easternmost of the main north–south U.S. Routes, parts of several others occupy corridors closer to the ocean. When the road system was laid out in the 1920s, US 1 was mostly assigned to the existingAtlantic Highway,which followed theAtlantic Seaboard Fall Linebetween thePiedmontand theAtlantic Plainnorth ofAugusta, Georgia.[3]At the time, the highways farther east were of lower quality and did not serve the major population centers.[4]FromHenderson, North Carolina,toPetersburg, Virginia,it is paralleled byI-85.Construction of the Interstate Highway System gradually changed the use and character of US 1, and I-95 became the major north–south East Coast highway by the late 1960s.

US 1 travels along the east coast ofFlorida,beginning at 490 Whitehead Street inKey West[5]and passing throughMiami,Hollywood,Fort Lauderdale,Boca Raton,West Palm Beach,Jupiter,Fort Pierce,Melbourne,Cocoa,Titusville,Daytona Beach,Palm Coast,St. Augustine,andJacksonville.The southernmost piece through the chain islands of theFlorida Keys,about 100 miles (160 km) long, is the two-laneOverseas Highway,originally built in the late 1930s after railroad tycoonHenry Flagler'sFlorida East Coast Railway'sOverseas Railroad,which was built between 1905 and 1912 on stone pillars, was ruined by the1935 Labor Day hurricane.The rest of US 1 in Florida is generally a four-lanedivided highway,despite the existence of the newerI-95not far away. Famous vacation scenic routeState Road A1Ais a continuous oceanfront alternate to US 1 that runs along the beaches of theAtlantic Ocean,cut only by assorted unbridged inlets and theKennedy Space CenteratCape Canaveral.North of Jacksonville, US 1 turns northwest towardAugusta, Georgia;US 17becomes the coastal route intoVirginia,whereUS 13takes over.[6]In Florida until the 1990s, US 1 used high-contrast markers (white text on a red background).[7]

Georgia

edit
Main article:U.S. Route 1 in Georgia

The part of US 1 inGeorgia,as it shifts from the coastal alignment in Florida to the Atlantic Seaboard Fall Line alignment in South Carolina, is generally very rural, passing through marshes and formerplantationsbetween the towns and cities ofFolkston,Waycross,Alma,Baxley,Lyons,Swainsboro,andAugusta.TheGeorgia Department of Transportationhas an ongoing plan to widen all of US 1 to four lanes with bypasses, which is more than 50 percent complete.

The Carolinas

edit
Main articles:U.S. Route 1 in South CarolinaandU.S. Route 1 in North Carolina

InSouth Carolina,US 1 generally serves mostly rural areas as it falls west ofI-95while the coastal areas are served by routes east of it. Starting in South Carolina, US 1 is paralleled byI-20along theAtlantic Seaboard Fall LinethroughAiken,Lexington,andColumbiatoCamdenandLugoff.US 1 functions as a local two-lane road with occasional boulevard stretches. After Camden, US 1 continues northeast away from any Interstate towardBethune,Patrick,McBee,andCherawwith no bypasses or four-lane sections except around Cheraw through theUS 52andSouth Carolina Highway 9(SC 9) concurrencies. After SC 9, it continues northward into North Carolina as a two -lane highway. TheSouth Carolina Department of Transportation(SCDOT) has no plans to widen or bypass any US 1 alignments northeast of Camden to the North Carolina line.

Between the South Carolina line and theUS 74bypass, US 1 is a two-lane road but sees a considerable amount of truck and tourist traffic of people cutting through from the US 74/US 220andI-73/I-74corridor attempting to reach points south and east. US 1 goes through downtownRockingham,with a bypass in the future plans. North of theNorth Carolina Highway 177(NC 177) junction, it becomes four lanes or greater, becoming asuperstreetwith limited access and then becoming a limited access freeway. US 1 becomes a major artery for the state as it moves north of Rockingham. AfterRichmond County,it goes intoMoore Countywith two expressway bypasses inSouthern Pines,Vass,andCameron.US 1 continues with theJefferson Davis Highwaylabel throughLee CountyandSanford,and on toCaryandRaleigh.US 1 runs concurrently withUS 64through most of Cary, where the freeway recently underwent a major renovation and improvements that added lanes in both directions.[8]North of Raleigh, US 1 (known as Capital Boulevard in northern Wake County) crossesI-540and then again becomes a four-lane divided arterial toI-85nearHenderson.TheNorth Carolina Department of Transportation(NCDOT) has begun a corridor study for this section of US 1.[9]Moreover, NCDOT is planning to finish four-laning US 1 in Richmond County past NC 177 with a Rockingham bypass to the east. There are no plans from SCDOT to widen US 1 from the state line. From Henderson into Virginia, US 1 runs parallel with I-85 as a two-lane local road until the state line, where Virginia hosts a continuous third center lane for alternate passing towardUS 58beforeSouth Hill.

Mid-Atlantic

Main articles:U.S. Route 1 in Virginia,U.S. Route 1 in the District of Columbia,U.S. Route 1 in Maryland,U.S. Route 1 in Pennsylvania,U.S. Route 1 in New Jersey,andU.S. Route 1 in New York

In theMid-Atlantic,US 1 generally serves some of themost populated areas of the east coast.ThroughVirginia,US 1 is paralleled by Interstates: the remainder ofI-85toPetersburg,I-95throughRichmondandFredericksburgtoAlexandria,andI-395intoArlington.In much of Virginia, US 1 was called theJefferson Davis Highwayby state law, although there are exceptions. South of Petersburg, it is known as Boydton Plank Road. Through some ofFairfax Countyand Alexandria, it is called the Richmond Highway.[10]In February 2021, Virginia renamed all remaining portions of the Jefferson Davis Highway in the state to Emancipation Highway beginning on January 1, 2022.[11][12]

US 1 crosses thePotomac Riverwith I-395 on the14th Street bridgesand splits to follow mainly14th StreetandRhode Island Avenuethrough theDistrict of Columbia.US 1 is at the minimum of three lanes (with alternate passing) from the North Carolina state line to Petersburg with occasional four-lane divided sections. North of Petersburg is a four-lane undivided roadway at the minimum to the DC line. The route of US 1 from Petersburg to the state line is parallel with theAtlantic Seaboard Fall Line.From Petersburg onward, it is parallel with I-95. After exiting DC intoMaryland,US 1 follows the Baltimore–Washington Boulevard, the first of several modern highways built along theWashington–Baltimore combined statistical areacorridor; I-95 is the newest, after theBaltimore–Washington Parkway.US 1 runs through theUniversity of Maryland, College Park,campus inCollege Park, Maryland.The route bypassesDowntown BaltimoreonNorth Avenueand exits the city to the northeast on Belair Road, gradually leaving the I-95 corridor, which passes throughWilmington, Delaware,for a straighter path towardPhiladelphia.Around and beyondBel Air,US 1 is a two-lane road, crossing theSusquehanna Riverover the top of theConowingo Dambefore entering Pennsylvania. (Routed further north, US 1 bypasses the state ofDelaware,unlike I-95.)[6]

The two-lane US 1 becomes a four-laneexpressway,officially known as the John H. Ware III Memorial Highway, afterthe Pennsylvania representative,just after crossing intoPennsylvania.This bypass extends aroundOxfordandKennett Square,merging into the four-lane dividedBaltimore Pikejust beyond the latter. AtMedia,US 1 again becomes a freeway—the Media Bypass—ending just beyondI-476.After several name changes, the road becomesCity Avenue,the western city limits ofPhiladelphia,at the end of which a shortoverlapwith theSchuylkill Expressway(I-76) leads to theRoosevelt Expresswayand then the 12-laneRoosevelt Boulevardpartly overlappingUS 13.US 1 again becomes a freeway after leaving the city, bypassingPenndelandMorrisvilleand crossing theDelaware RiverintoNew Jerseyon theTrenton–Morrisville Toll Bridge.[6]

After crossing intoNew Jerseyin Mercer County, US 1 continues on theTrenton Freewaythrough the state capital ofTrentonandLawrence Townshipas a four-lane freeway. As the freeway ends, the four-lanedivided highwayupgrades to six lanes north ofI-295passing through thePenns Necksection ofWest Windsor.Through Penns Neck is a series of traffic signals. TheNew Jersey Department of Transportation(NJDOT) is looking to revamp the highway through this area by replacing traffic signals with grade separations. The highway entersMiddlesex CountythroughPlainsboro TownshipandSouth Brunswick,where the highest point resides.[13]By Forrestal Village, the highway downgrades from six to four lanes until after Finnegans Lane inNorth Brunswick.Northward, it continues throughNew Brunswickas a short limited-access highway until theCounty Route 529(CR 529)/Plainfield Avenue traffic signal inEdison.Through Edison andWoodbridge Township,US 1 has a mix of boulevard and limited-access segments and continues to do so after theUS 9juncture in theAvenelsection of Woodbridge. TheUS 1/9concurrencycontinues through the rest of the state. The six-lane divided highway remains throughRahwayinUnion CountyandElizabeth,until it reachesNewark Liberty International Airport,where it becomes a dual carriageway freeway around downtownNewarkinEssex Countywith a 2–2–2–2 configuration. The historicPulaski Skywaytakes US 1/9 intoJersey City,and the route exits the freeway at theTonnele Circleto head north intoBergen County.US 1/9 turns ontoUS 46as a limited-access highway, and the three routes run northeast to theGeorge Washington Bridge Plaza,where they merge into I-95. US 46 ends in the middle of the bridge, which crosses theHudson RiverintoNew York,andUS 9exits just beyond ontoBroadwayinManhattan,but US 1 stays with I-95 onto theCross Bronx Expressway,exiting inthe Bronxonto Webster Avenue. Two turns take US 1 viaFordham Roadto Boston Road, which it follows northeast out of the city, becoming Boston Post Road inWestchester County,never straying far from I-95. From the Bronx to the state line, it is a local road with two lanes in each direction, except inRyewhere it has a single lane in each direction. As it entersGreenwich, Connecticut,it continues as a two-lane local road.

New England

edit
Main articles:U.S. Route 1 in Connecticut,U.S. Route 1 in Rhode Island,U.S. Route 1 in Massachusetts,U.S. Route 1 in New Hampshire,andU.S. Route 1 in Maine

InNew England,US 1 generally serves large cities in a side street capacity. InConnecticut,US 1 serves the shore ofLong Island Soundparallel toI-95.BeyondNew Haven,the highway travels east–west, and some signs in the state indicate this rather than the standard north–south. While I-95 inRhode Islandtakes a diagonal path toProvidence,US 1 continues east along the coast throughWesterlytoWakefield-Peacedale,where it turns north and followsNarragansett Bay.Most of this part is a four-lanelimited-access highway,providing access toRoute 138towardNewport.AfterRoute 4splits as a mostly-freewayconnection to I-95, US 1 becomes a lower-speed surface road, passing throughWarwick,Providence, andPawtucket.The route parallels I-95 again through Providence and Pawtucket and intoMassachusetts,traveling towardBostonas a four-lane road. When it reachesDedham,US 1 turns east and becomes a freeway through metropolitan Boston,concurrentwith I-95 andI-93east toBraintreeand north throughDowntown Boston.TheTobin BridgeandNortheast Expresswaytake US 1 out of Boston, after which it again parallels I-95 as a high-speed surface road throughNewburyportto the New Hampshire state line.[6]

The short portion of US 1 inNew Hampshirefollows the historic Lafayette Road, staying close to I-95, passing throughPortsmouthbefore crossing thePiscataqua RiveronMemorial Bridge,which was demolished and replaced during 2012–2013, leaving a temporary gap in US 1. During construction, drivers had to detour to one of two other nearby bridges carryingUS 1 Bypassor I-95. WithinMaine,US 1 begins as a parallel route to I-95 near theAtlantic Ocean.AtPortland,I-95 splits off to the north, andI-295heads northeast paralleling US 1 toBrunswick.There US 1 turns east as a mostly two-lane road along the coast toCalais;much of this portion is advertised as the "Coastal Route" on signs. North from Calais, US 1 follows theCanadian border,crossing I-95 in Houlton and eventually turning west and southwest to its "north" end at theClair–Fort Kent BridgeinFort Kent.The shortRoute 161extends north on theNew Brunswick(Canada) side of the bridge toRoute 120,a secondary east–west route fromEdmundston,New Brunswick,west toQuebec Route 289towardSaint-Alexandre-de-Kamouraska,Quebec.[6]

History

edit
The beginning of US 1 as of March 1951

The direct predecessor to US 1 was the Atlantic Highway, anauto trailestablished in 1911 as the Quebec–Miami International Highway. In 1915, it was renamed the Atlantic Highway,[14]and the northern terminus was changed toCalais, Maine.[15]Due to the overlapping of auto trail designations, portions of the route had other names that remain in common use, such as theBoston Post RoadbetweenBostonandNew York City,theLincoln Highwaybetween New York andPhiladelphia,the Baltimore Pike between Philadelphia andBaltimore,and theDixie Highwayin and south of easternGeorgia.North ofAugusta, Georgia,the highway generally followed theAtlantic Seaboard Fall Line,rather than a more easterly route through theswampsof theAtlantic Plain.[16]Brickell Avenueis the name given to the two-mile (3.2 km) stretch of US 1 inMiami, Florida,just south of theMiami Riveruntil theRickenbacker Causeway.

When theNew England road marking systemwas established in 1922, the Atlantic Highway withinNew Englandwas signed asRoute 1,with aRoute 24continuing north toMadawaska;[17]New Yorkextended the number toNew York Cityin 1924 with its ownRoute 1.[18]Other states adopted their own systems of numbering; by 1926 all states butMarylandhad signed the Atlantic Highway as various routes, usually changing numbers at the state line. In 1925, theJoint Board on Interstate Highwayscreated a preliminary list of interstate routes to be marked by the states,[19]including US 1 along the Atlantic. This highway began atFort Kent, Maine,and followed the existing Route 24 toHoulton,as well asRoute 15toBangor,beyond which it generally followed the Atlantic Highway to Miami.[20]In all states butGeorgiathat had numbered theirstate highways,Route 1 followed only one or two numbers across the state.[21]The only significant deviation from the Atlantic Highway was betweenAugusta, Georgia,andJacksonville, Florida,where Route 1 was assigned to a more inland route, rather than following the Atlantic Highway viaSavannah.[4]

One of the many changes made to the system before the final numbering was adopted in 1926 involved US 1 in Maine. The 1925 plan had assigned US 1 to the shorter inland route (Route 15) between Houlton and Bangor, whileUS 2followed the longer coastal route via Calais. In the system as adopted in 1926, US 2 instead took the inland route, while US 1 followed the coast, absorbing all of the former Route 24 and Route 1 in New England.[22][23]Many local and regional relocations, often onto parallelsuperhighways,were made in the early days of US 1; this included the four-lane dividedRoute 25inNew Jersey,completed in 1932 with the opening of thePulaski Skyway,[24]and a bypass of Bangor involving theWaldo–Hancock Bridge,opened in 1931.[25]TheOverseas Highwayfrom Miami toKey Westwas completed in 1938 and soon became a southern extension of US 1.[26]

With the construction of theInterstate Highway Systemin and after the 1950s, much of US 1 from Houlton to Miami was bypassed byI-95.Between Houlton andBrunswick, Maine,I-95 took a shorter inland route, much of it paralleling US 2 on the alignment proposed for US 1 in 1925. BetweenPhiladelphiaandBaltimore,I-95 leaves US 1 to pass throughWilmington.Most notably, I-95 and US 1 follow different corridors betweenPetersburg, Virginia,andJacksonville, Florida;while US 1 followed the Atlantic Seaboard Fall Line west of the coastal plain, I-95 takes a more direct route through the plain and its swamps. Although some of this part of US 1 was followed by other Interstates—I-85between Petersburg andHenderson, North Carolina,andI-20betweenCamden, South Carolina,andAugusta, Georgia—the rest remains an independent route with four lanes in many places. By the late 1970s, most of I-95 had been completed, replacing US 1 as the main corridor of the east coast and relegating most of it to local road status.[27]

US 1 has six three-digit auxiliary routes. In numerical order, these are:

US 101,despite its number, is not an auxiliary route, but rather considered a primary U.S. Route in its own right as major highway west of the formerUS 99on the west coast of the U.S. (In the numbering scheme, its first "digit" is "10".)
