List of unused highways in the United States

From IdeaWazaWiki

An unused highway may reference a highway or highway ramp that was partially or fully constructed but was unused[1][2][3][4][5][6][7][8][9] or later closed.[10][11][12] An unused ramp can be referred to as a stub ramp,[13] stub street,[2][14][15] stub-out,[2] or simply stub.[16][17] The following is a list:

United States

Alabama

Birmingham

  • Between Exits 121 and 123 along Interstate 20/Interstate 59 is an abandoned stretch of mainline interstate along the southbound lanes. These lanes were utilized in 1977 as temporary lanes while the mainlines were being repaired as a result of sinkhole formation.[18] [19]

Gadsden

Tuscaloosa

Centreville

Montgomery

  • Construction has started on a bypass of downtown,[23] east of the city center. The bypass is to be in the southeastern quadrant of the area, intersecting Interstate 85 near mile marker 14 and Interstate 65 near mile marker 163.[24] An aerial view shows there is only a short portion of the bypass graded. Part of the route is signed Alabama State Route 293. [24]

Mobile

Phenix City

Arkansas

Jacksonville

North Little Rock

  • The grading and underpass for the previous left exit/entrance ramp from U.S. Route 67 southbound to Interstate 40 eastbound are still visible. A new ramp was built to connect to and from the right. [30]

Delaware

Wilmington

Dover

Corbit

  • Labeled S Dupont Highway by some maps, obsolete pavement exists as the old alignment of U.S. Route 13. The newer Delaware State Route 1 has taken the place of what was once U.S. 13.[30] The southbound lanes are still in use but the northbound lanes sit unused. [38]

Indiana

Jeffersonville:

Indianapolis:

  • There are grading and stub ramps at the Interstate 70 and 65 interchange (North Split) downtown where Interstate 69 was supposed to have connected, but was cancelled in the 1970s due to community opposition.[33] [40]

Kansas

Lawrence:

  • South Lawrence Trafficway, which was intended to route Kansas State Route 10 around the city rather than through it. The western section was completed in 1996. An overpass was constructed over U.S. Route 59 to continue the route eastward, but all traffic must exit before reaching it. [41]

Topeka

  • The Oakland Expressway was originally intended to extend further than the US 24, but the highway was only completed up to the US 24. The canceled extension left an unused cloverleaf ramp that was to run from the eastbound US 24 to the Oakland Expwy extension. [42]

Kentucky

Hopkinsville:

Louisville:

Newport:

Princeton:

Middlesboro

Louisiana

Shreveport:

  • The northern terminus of Interstate 49 at the Interstate 20 interchange contains numerous stub ramps that indicated a previously designed northern extension. As early as 1999,[43] this idea was scrapped with the adoption of the Future 49/High Priority Corridor 1, a plan to extend I-49 to Kansas City. It was due to high costs in acquiring right of way and community opposition.[44] This plan currently has I-49 routed onto Louisiana State Route 3132 south of the city. Currently, there are talks to turn the current stretch of I-49 from Louisiana 3132 north to its current northern terminus into Interstate 149.[45] [50]

New Orleans:

  • Louisiana State Highway 3139 (Earhart Expressway) in Jefferson Parish features several stub ramps, as it was never fully completed. The northern terminus was planned to be Louisiana State Highway 49 (Williams Boulevard) but it currently only reaches Louisiana State Highway 3154. Two mainline stubs exist at the Louisiana 3154 exit, leaving Louisiana 3139 to utilize the ramps instead. [53] Two more stubs were to be part of a direct connection to Causeway Boulevard. That connection was never completed, leaving the stubs [54] and an abandoned grassy right-of-way. [55] Another stub, this one an off-ramp, exists on southbound side near the eastern end of the limited-access portion. [56] It had a companion on-ramp stub on the northbound side,[47] but it has since been completed. An additional off-ramp stub on the southbound side [57] was to have connected to the proposed Interstate 310/Vieux Carre Riverfront Expressway south of the French Quarter had it continued as a freeway south into Orleans Parish.[48]

Boutte

Maine

Saco

  • Interstate 195 has an interchange with the Maine Turnpike/Interstate 95 at its western terminus. As originally constructed, both ramps were clover ramps, but subsequently, the clover ramp handling traffic exiting the turnpike was replaced between 1988 and 1998,[52] turning the interchange into a trumpet. The grade for the original clover ramp remains. Also, the eastbound ramp from the Turnpike crosses a bridge meant for two lanes, but only has one and shifts over to the left, as can be seen from the link. [59]

Minnesota

Minneapolis

  • Interstate 335, a spur of Interstate 35W, was proposed to connect I-35W with Interstate 94 just north of downtown. The project got as far as right-of-way acquisition and grading for and paving of exit ramps at the east end on I-35W before it got cancelled due to local opposition. The southbound lanes of I-35W contain the vestiges of an entrance ramp from I-335 and a ramp to I-335 from the northbound lanes is visible despite having been demolished. Both are near the Hennepin Avenue bridge. [61] North of this, the other half of the proposed full interchange is also visible. The exit from I-35W south to I-335 west is still graded and a stub of pavement that still exists was to be the ramp from I-335 east to I-35W north. [62] A northbound exit from I-35W to Johnson Street makes a rather long dogleg that would have accommodated this ramp and the redundant Johnson Street exits support an I-335 merge. In the same area, a pavement stub existed in the I-35W median but has since been removed.[54] [63]
  • At the west end of the proposed Interstate 335[54] there is pavement to support a wider ramp on the exit from eastbound Interstate 94 to N 3rd Street. It was to be the ramp to eastbound I-335.[55] [64]

North St. Paul

  • In the late 1950s, what is now Minnesota Highway 5 was proposed to follow a more direct, part-freeway/part-arterial routing between downtown St. Paul and the existing 4-lane segment along MN 5 east of Minnesota Highway 120. The northern MN 5/MN 120 junction includes some ramp grading for what was then planned as a folded diamond interchange, but cancelled along with the rest of the proposed highway sometime in the 1970s.[56] What was to be the eastbound off-ramp loop is now used as an access road to a Minnesota Department of Transportation staging area, as can be seen in aerial image.

Monticello

  • Interstate 94 exit 195 for Wright County Road 75 (westbound only) and the corresponding eastbound on-ramp were closed and replaced in 2006 by exit 194 (Wright County Roads 18 and 39),[57] with ramps from the former exit 195 barricaded but still intact. This Google map image shows the former exit 195 visible in the satellite image with the layout of the current exit 194 drawn in orange: [65]

Mississippi

Pearl

Hattiesburg

  • Right-of-way for a loop ramp and a collector-distributor roadway exists at the interchange of Interstate 59 and U.S. Route 98 at the southern edge of the city. [67] U.S. 98 may one day be extended west from the interchange to bypass the city.

Vicksburg

Missouri

Hillsboro

Kansas City

  • An abandoned on-ramp can be seen at Interstate 70 and East Truman Road. The roadbed is still visible, and a bridge over East Truman Road remains unused. [74]
  • There used to be an on-ramp to westbound Interstate 70 from Norton Avenue. It was removed after 1995,[59] eliminating a left-hand merge. [75]

Lexington

St. Louis

  • A proposed Missouri State Route 755 was to start at Interstate 44 at its interchange with Interstate 55 and connect to Interstate 70, interchanging with Interstate 64/U.S. Route 40. The freeway would have looped to the west of downtown.[60] Indications of the cancelled freeway can be seen in this old satellite image, showing a pavement stub on the Lafayette Avenue exit ramp that has since been removed. There is also blocked off lane on eastbound I-44 that would have been a ramp to northbound Missouri 755.[61] [77] It was to follow Grattan Street, but since the freeway's cancellation, it and Grattan have mostly been replaced by Truman Parkway. Ramp stubs can also be seen around the exits for 20th, Chestnut, and Market Streets from I-64. [78]. A sufficiently large right of way is present there as well.
  • Due to the building of new Busch Stadium, the 8th Street on-ramp to eastbound Interstate 64 was demolished,[62] leaving a ramp stub on the interstate. It is not viewable from the air due to the elevated freeway design downtown, but can be seen while driving. It was a left-entry ramp. The old ramp design can still be seen on a Microsoft Research maps satellite image. [79]
  • Spring Avenue once had a viaduct over a rail yard that connected Forest Park Avenue with Gratiot Street. The viaduct was closed and partially demolished sometime after 1991 (and perhaps even after 1998 based on this satellite image). The south end is barricaded by a mound of gravel and the vegetation is overgrown. The north end is blocked by a fence, followed by semi trailers and jersey barriers. Between Interstate 64 and where Scott Avenue would intersect Spring, the viaduct has been demolished and Spring exists as an at-grade street[63] off of Market Street. The remaining elevated roadway has been demolished. [80]
  • The MacArthur Bridge formerly carried traffic across the Mississippi River starting 1917, carrying U.S. Route 66 and U.S. Route 460 at times. Due to deterioration, the bridge was closed to automobile traffic in 1981, though trains still use the bridge today. Some of the connections were demolished, including the approach in Illinois [81], though an unused bridge frame [82] and wide supports [83] still stand. Remnants of approaches are used as a parking lot on the west side [84] or are just shut off from traffic by jersey barriers [85]. Pavement still exists on the bridge, though only up to the Illinois side. [86]

Sunset Hills

  • The Interstate 270/Interstate 44 interchange used to be a full cloverleaf with collector/distributor ramps. [87] Two of the loops were replaced with flyovers; the eastbound I-44 ramp to northbound I-270 and the westbound I-44 ramp to southbound I-270. [88] Grading for the demolished loop ramps is still visible from above.

Nebraska

Omaha

  • At the intersection of Interstate 480 and U.S. Route 75 downtown, there are several bridges and ramps that would have connected to the West Expressway, but the West Expressway project was canceled. The interchange is currently under construction and unnecessary bridges and ramps will be removed.[64] [89]

Dawes County

  • An undivided portion of U.S. Route 385 in western Nebraska has a parallel path for approximately 4 miles ({{rnd/cTemplate:Rnd/b|6.4|(1−0)|1}} km) which is graded, with some bridges constructed, but otherwise unpaved. (Old highway alignment that parallels current alignment.)[90]

Oklahoma

  • In Tulsa, a section of Interstate 44 was bypassed when the Creek Turnpike was constructed, and I-44 was routed through a new interchange with the northern terminus of the Creek Tpk.[65] The existing pavement is no longer used, and a city street (Pine Street) still crosses the abandoned highway on a bridge. [91] I-44's interchange with Oklahoma State Route 66 also shows signs of the former routing of I-44. There are pavement stubs and grading that indicated a different configuration. [92][93]

Providence

  • There is a stub off ramp from Interstate 195 westbound where Exit 1 used to be. It used to carry traffic into the heart of the financial/court district, as this 2002 picture shows. As of Nov. 2008, there were still signs posted for it. It is currently being used occasionally for staging of construction vehicles working on the new I-195/Interstate 95 connection realignment project. [100]

South Carolina

Charleston

Columbia

South Dakota

Rapid City

  • There used to be an Exit 66 on Interstate 90 east of Rapid City for Box Elder and the Ellsworth Air Force Base. This exit was closed October 1, 2003 and the pavement ripped up. A new exit (Exit 67) opened a few months earlier that supplanted Exit 66. This exit is for Liberty Boulevard, which leads right to the gates of the Ellsworth A.F.B. Local officials feared the potential closing of the base and successfully lobbied the state and federal government to construct a new interchange. The exit change will also help keep commercial development away from the runways.[76][77] While the pavement is gone, you can see grading outlining the old ramps. [103] Old configuration

Tennessee

Maryville, Tennessee

  • At the end of the Highway 140 (Pellissippi Parkway) where the parkway meets Highway 33 (Old Knoxville Highway) there are two stubs that end just before the intersection.[104]

Knoxville:

  • At the southern end of the James White Parkway (Tennessee State Route 71). The parkway is planned[78] to extend to connect to Chapman Highway (U.S. Route 441) somewhere in the vicinity of Gov. John Sevier Highway, but construction has been stalled for several years now, and the parkway now terminates at Sevierville Pike. All traffic enters or leaves the parkway north of Sevierville Pike, but the bridge over the parkway has been completed, and the mainline extends under the bridge, terminating abruptly. [105]
  • Just east of the Interstate 40/Interstate 275 interchange along the westbound lanes are a three stub ramps. The first was intended to be an expansion of the mainlanes through downtown and the second two were to be an ramps to and from West Magnolia Avenue. [106]. Both will be eliminated in 2008 as part of the SmartFix reconstruction of I-40 through downtown Knoxville.[79]

Memphis:

  • Three pavement stubs exist as a result of a cancelled freeway on the north side of the city. One stub exists just after the Hernando DeSoto Bridge off the elevated ramp from eastbound Interstate 40 to Riverside Drive/Front Street. The ramp may not be visible to drivers, as jersey barriers block it off; however, the unfinished ramp is visible from ground level. [107] On the Jackson Avenue to westbound I-40 on-ramp is another ramp stub. [108] This, along with the above ramp stub, was to connect to a proposed freeway that ran north from this interchange along Mud Island to the Tennessee State Route 300 and U.S. Route 51 (Thomas Street) interchange, where there is also ramp stub.[80] [109] This is also the site where future Interstate 69 will enter Memphis.[81]
  • A stub ramp exists at the Interstate 40/Interstate 240 interchange in East Memphis. [111] It will eventually allow for a two-lane flyover for I-40 westbound to continue through the interchange, relieving the current one-lane ramp of the increased traffic in the region. A corresponding flyover in the eastbound direction will also be built (this will be the fourth level of the interchange) and replace the existing one-lane ramp.[83] In addition, grading remains as the remnant from a loop ramp from westbound I-40 to westbound I-240 which was destroyed after a two-lane flyover replaced it.
  • At the intersection of Interstate 55 and U.S. Highway 51 / Elvis Presley Boulevard, a loop ramp has been eliminated. The ramp ran from northbound I-55 to southbound U.S. 51 and was eliminated during the widening of I-55 in 2001 due to weaving conflicts with an on-ramp from Brooks Road immediately before the loop. [112]

Vermont

In Burlington:

  • At the west end of Interstate 189 at U.S. Route 7, there are some ramp stubs and about a half mile of an unused highway west of that interchange. There are plans for this to be part of a boulevard into downtown Burlington.[86][118]

Bennington:

Essex Junction:

  • On both the north and south ends of Vermont State Route 289, there are stubs that indicate an extension of the highway. Original plans had it intersect with Interstate 89 near Williston to the south, and with Interstate 89 near Colchester to the north, to complete an auxiliary highway. [120] 289 also appears to have an unfinished jughandle that is partially paved and graded and leads to what appears to be a soccer field. [121]

Milwaukee:

  • The proposed Stadium Freeway was to have a southern terminus at Interstate 894/Interstate 43 in southern Milwaukee. While the freeway was never built south of National Ave, a graded ramp exists just east of W. Loomis Rd. The ramp was to come from I-894/43 eastbound going north. It was a complete interchange, but one ramp was demolished[87] (it appears it was a flyover as the top level) and there is a hint of a left-exit ramp just west of the proposed interchange. Other ramps exist at this unusually wide interchange and lead to and from a Park & Ride and the left on-ramp from the Park & Ride heading east hints at a planned major interchange. Seen here. [124]
  • The Stadium Freeway (signed U.S. Route 41 in this section) was not completed to its planned northern terminus either. It currently ends at Lisbon Road with a wide median and pavement stubs. [125] It was to meet the proposed and planned Park Freeway West in this area and travel northwest for about a mile and head north, intersecting the Bay and Fond du Lac Freeway on its proposed alignment to Interstate 43 (North-South Freeway) in Ozaukee County, where it would end. The extension north of Lisbon Rd. was cancelled in 1974.[87]
  • Because a part of the Lake Freeway was canceled after it was planned,[88] extra pavement that was built in anticipation of the northerly continuation, named the "Downtown Loop Closure," sits unused. In one form it is a ramp stub that was to carry the northbound lanes and in another it is a wide bridge that carries less traffic (than originally intended) from Lincoln Memorial Drive to southbound Interstate 794.[87] [126]

Elkhorn:

  • U.S. Route 12 abruptly ends at Wisconsin State Highway 67 just north of the city. Northbound lanes must exit and the mainline continues for about 50 yards. Southbound lanes actually utilize an underpass that was built to carry U.S. 12 northwest toward Whitewater. More unused pavement exists as a never completed on-ramp from southbound U.S. 12 to Wisconsin 67 and an on-ramp (broken up by the operational "flyunder" ramp) from Wisconsin 67 to northbound U.S. 12. Grading is evident on the west side of the interchange. The unbuilt expressway was to be part of a Madison to Chicago route that was limited by Illinois' participation.[89] [127]

Genoa City:

  • The southern terminus of the interstate quality U.S. Route 12 ends just east of the city. Southbound lanes exit onto a ramp with an interchange with Wisconsin State Highway 120. Northbound lanes merge onto a stub just before a Welcome to Wisconsin rest area. U.S. 12 was to be a part of a fully controlled access freeway from Madison to Chicago, with a connection to the Illinois Tollway System at the state line.[89] There is grading south of the interchange as well.
