List of future Interstate Highways

In the United States, future Interstate Highways include proposals to establish new mainline (one- and two-digit) routes to the Interstate Highway System. Included in this article are auxiliary Interstate Highways (designated by three-digit numbers) in varying stages of planning and construction, and the planned expansion of existing primary Interstate Highways.

Congressionally designated future Interstates

edit

Several Congressional High Priority Corridors have been designated as future parts of the Interstate Highway System by the Intermodal Surface Transportation Efficiency Act (ISTEA) in 1991 and amendments to Section 1105. By law, they will become interstates when built to Interstate standards and connected to other interstates.[2][3]

California State Route 99

edit
This section is an excerpt from California State Route 99 § Future.[edit]

Caltrans' long-range plans recommend that SR 99 be upgraded to Interstate Highway standards between its southern end and Sacramento, which would require upgrading some substandard sections. Caltrans once suggested the route could be designated as either I-7 or I-9, in accordance with the Interstate Highway System's numbering standards (being just east of and parallel to I-5).[4]

Proposed routes for the Interstate Highway would have it go from the split with I-5 at Wheeler Ridge (Wheeler Ridge Interchange) north through Bakersfield and Fresno to Stockton, where the route would turn west via the SR 4 freeway to a terminus at I-5 in the central part of that city. An alternate proposed terminus is located at the I-5/US 50/Capital City Freeway junction in Sacramento, where the future Interstate, after continuing north from Stockton along SR 99, will turn west along the Capital City Freeway, already an Interstate Highway (unsigned I-305), to connect with I-5, which extends north toward Redding. This also serves as a connector to the existing northern portion of SR 99. The future Interstate's prospects for development to appropriate standards are tied to the Caltrans "Route 99 Corridor Enhancement Master Plan"; this document posits that when and if Interstate status is conferred, the route will be designated I-7 or I-9.[5] The route is to remain roughly parallel to I-5, serving major cities in California I-5 does not, including Fresno and Bakersfield.

In August 2005, with the passage of that year's SAFETEA-LU federal transportation legislation, SR 99 from Wheeler Ridge to Stockton and beyond to Sacramento was designated as High Priority Corridor 54, the California Farm-to-Market Corridor; this legislation also designated that corridor as a future segment of the Interstate Highway System.[6]

Interstate 42 (Oklahoma–Arkansas)

edit

Future Interstate 42
LocationNoble County, OK to Springdale, AR
Length190 mi (310 km)

On May 20, 2021, Senator Jim Inhofe, of Oklahoma, introduced legislation to designate the portion of US 412 between I-35 in Noble County and I-49 in Springdale, Arkansas as Future Interstate 42 (I-42).[7][8] The bill, titled the "Future Interstate in Oklahoma and Arkansas Act" (S. 1766), was cosponsored by senators John Boozman and Tom Cotton, both of Arkansas. The senators' stated reasons for seeking an Interstate designation along US 412 included encouraging economic development, expanding opportunities for employment in the region, making travel safer and shipping easier, attracting new businesses, and better connecting rural and urban communities. Other supporters of the measure include Mayor G. T. Bynum of Tulsa, and the heads of both ODOT and the Arkansas Department of Transportation (ArDOT).[9] The language of the bill was later included in the Infrastructure Investment and Jobs Act (H.R. 3684). Interstate 42 (I-42) was the proposed designation but was withdrawn.[10] ArDOT and ODOT later resubmitted the application to the Spring 2024 meeting; AASHTO approved the route as Interstate 42, conditional on it being upgraded to Interstate standards.[11]

Future Auxiliary Interstate Highways

edit

Interstate 195 (Washington D.C.)

edit
Future Interstate 195
LocationWashington
Length2.41 mi (3.88 km)

The current Interstate 695 will be eliminated and be replaced with an extension of Interstate 395. The original Interstate 395 through the 3rd Street Tunnel will be renumbered as Interstate 195.[12]

Interstate 214

edit
Future Interstate 214
LocationBryan–College Station

Interstate 214 is proposed to be a beltway around Bryan-College Station in Texas.[13]

Interstate 222

edit
Future Interstate 222 marker
Future Interstate 222
LocationGraysville to Brookside
Length2.26 mi (3.64 km)

Interstate 222 is a future auxiliary Interstate Highway that will be a connector between I-22 and the proposed I-422 near Birmingham, Alabama. There will be no exits other than its termini. The highway has been proposed because an interchange directly between I-22 and I-422 cannot be built due to environmental issues.[14]

Interstate 274 (North Carolina)

edit
Future Interstate 274
LocationWinston-Salem
Length16.83 mi (27.09 km)

Interstate 274 is the future designation for the western half of the beltway, currently designated as NC 452. When completed, it will connect US 158, near Clemmons, North Carolina, to Future I-74/Future I-285/US 52, in Bethania. I-274 first appeared on North Carolina Department of Transportation (NCDOT) planning maps in the early 2000s but was later disused for over a decade since. On May 20, 2019, the American Association of State Highway and Transportation Officials (AASHTO) approved a request to establish Future I-274. Justification given by NCDOT was that the 16.83-mile (27.09 km) section would satisfy a great need to alleviate congestion in Winston-Salem and connect the western portion of the urbanized area.[15]

Interstate 343

edit
Future Interstate 343
LocationBroken Arrow To Webbers Falls
Length53.1 mi (85.5 km)

Interstate 343 is a proposed designation for the existing Muskogee Turnpike, the current designated number is Oklahoma State Highway 351.[16]

Interstate 365

edit
Future Interstate 365 marker
Future Interstate 365
LocationPark City to Somerset
Length88.376 mi (142.227 km)

Interstate 365 is a proposed redesignation of the Cumberland Parkway once it is upgraded to Interstate standards. On August 5, 2021, Congress released a new infrastructure bill that proposed to designate the whole length of the Cumberland Expressway as a Future Interstate, with the designation of I-365.[17] The designation would need approval from AASHTO, the FHWA, and upgrades of several interchanges and other improvements before the designation could be implemented.

Interstate 369 (Kentucky)

edit

Interstate 369 is planned to follow the entire Audubon Parkway with the western terminus to Interstate 69 being called Interstate 69 Spur.[18]

Interstate 422

edit

Locationsouth of Bessemer to Argo
Length52.5 mi (84.5 km)

Interstate 422 is a proposed beltway in Birmingham. Interstate 422 will not directly connect to I-22 so therefore a new connector known as Interstate 222 is proposed. It is also called Corridor X-1. A timeline for construction to begin has not been established.[19]

Interstate 490 (Illinois)

edit
Future Interstate 490 marker
Future Interstate 490

Length6.00 mi (9.66 km)

Interstate 490, also known as the O'Hare West Bypass and Western O'Hare Beltway, is a six-mile (9.7 km) electronic toll highway and a beltway that is currently under construction near Chicago, Illinois; it will run along the west side of O'Hare International Airport. The tollway will connect I-294 (Tri-State Tollway) to a western access point to the airport. From there, it will continue northward to an extension of Illinois Route 390 (IL 390, formerly known as the Elgin-O'Hare Expressway) and I-90 (Jane Addams Memorial Tollway). It is proposed to be finished by 2027.[20]

Interstate 569
