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

Several Congressional High Priority Corridors have been designated as future parts of the Interstate Highway System by the Intermodal Surface Transportation Efficiency Act and amendments. By law, they will become interstates when built to Interstate standards and connected to other interstates.

Interstate 3

Interstate 3 is the proposed designation of an Interstate Highway Corridor under development in the Southeastern United States. It is planned to run from Savannah, Georgia, to Knoxville, Tennessee. Its number does not follow standard numbering conventions; under established numbering conventions, I-3 would normally run west of I-5 along the Pacific Coast. The unnumbered Interstate was established by the Safe, Accountable, Flexible, Efficient Transportation Equity Act: A Legacy for Users (SAFETEA-LU) legislation that also provided for Interstate 14. The "Interstate 3" designation has not been officially accepted by American Association of State Highway and Transportation Officials (AASHTO) or the Federal Highway Administration (FHWA), but is being used by the Georgia Department of Transportation and others to identify the highway. The number comes from the 3rd Infantry Division, which is based in Georgia. The exact route has not been finalized.

Interstate 7 or 9

Interstate 7 or 9 has been proposed by Caltrans for State Route 99 in central California. It would go from the split with I-5 at Wheeler Ridge ( Wheeler Ridge Interchange) north through Bakersfield and Fresno to Stockton, where the proposed route(s) turns 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(s), after continuing north from Stockton along Route 99, can turn west along the Capital City Freeway, already an Interstate route (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 Highway 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. 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 System.

Interstate 42 (Oklahoma–Arkansas)

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). The bill, titled the "Future Interstate in Oklahoma and Arkansas Act" (), 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). The language of the bill was later included in the Infrastructure Investment and Jobs Act (). Interstate 42 (I-42) was the proposed designation but was withdrawn. 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.

Interstate 67

Interstate 67 has been a proposed number for at least three highways.

I-67 was originally the designation given to a never-built highway connecting Kalamazoo, Michigan, to the east side of Elkhart, Indiana, as part of the original Interstate numbering plan in 1957. A planning map shows a freeway along this routing intersecting the Indiana Toll Road just west of the State Road 19 interchange. The Michigan State Highway Department officially requested switching the I-67 designation to a route from Benton Harbor to Grand Rapids in 1958, and in the process proposed the northerly extension of the original I-69 from the I-80/I-90/Indiana Toll Road to Lansing. The I-67 designation was denied by the American Association of State Highway and Transportation Officials which then assigned I-196 to the Benton Harbor to Grand Rapids route, west of the I-96 junction near Grand Rapids.

Indiana has proposed using the I-67 designation for the freeway upgrade of US 31 currently under construction between Indianapolis and South Bend, possibly continuing northward via the US 31 freeway to Benton Harbor, Michigan, and going northward from there along existing I-196 to Grand Rapids. The Indiana Senate unanimously passed a resolution calling for federal funding for this proposal and the I-67 designation in 2003. Meanwhile, Indiana expedited the upgrading of three major sections on US 31 between Indianapolis and South Bend including the Kokomo Bypass. This was done using funds received through the 2006 Major Moves deal. Such a proposal would put I-67 in the proper place in the grid (it is the only number available for that route).

A third, much shorter, proposal in 2011 by the I-67 Development Corporation from the Owensboro, Kentucky, area involves continuing the proposed I-67 in Indiana along a route parallel to US 231 from Crane, Indiana, to Bowling Green, Kentucky. Much of the proposed route already exists and is close to Interstate grade. Only the northern third from Dale, Indiana, to Crane remains unfinished. It would use the Natcher Bridge to cross the Ohio River, Kentucky's I-165 and Indiana's Lincoln Parkway, an expressway facility that would need to be fully upgraded to Interstate standards. It would go around the cities of Jasper and Huntingburg in Indiana as well as Owensboro, Hartford, and Morgantown, Kentucky, and end at Bowling Green. It could also be linked to the first proposal by overlapping I-67 with the currently under construction I-69 from Indianapolis to Crane.

Future Auxiliary Interstate Highways

Interstate 169 (Tennessee)

Interstate 169 is proposed to run along Tennessee State Route 22 from Union City to Martin.

Interstate 195 (Washington D.C.)

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.

Interstate 214

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

Interstate 222

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.

Interstate 274 (North Carolina)

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 section would satisfy a great need to alleviate congestion in Winston-Salem and connect the western portion of the urbanized area.

Interstate 310 (Mississippi)

Interstate 310 is a proposed Interstate in Mississippi. Construction was supposed to begin in 2008 but never occurred. Much of the land clearing was done.

Interstate 365

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. 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)

Interstate 369 is planned to follow the entire Audubon Parkway with the Western terminus to Interstate 69 being called Interstate 69 Spur.

Interstate 380 (Ohio)

Interstate 380 is proposed to start from the southern terminus of Ohio SR 8 at Akron to the intersection of I-271. The project has not been approved yet.

Interstate 422

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.

Interstate 490 (Illinois)

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.

Interstate 569

In April 2019, the Western Kentucky Parkway was originally proposed as Interstate 369 before being changed Interstate 569 in December 2019 as the Audubon Parkway was proposed to be Interstate 369.

Interstate 685 (Alabama)

Interstate 685 is planned to follow a portion of Interstate 85 when I-85 gets altered on the Montgomery Outer Loop.

Interstate 685 (North Carolina)

Interstate 685 is a proposed Interstate planned to run along current US 421. It will be upgraded to Interstate highway standards from Interstate 40 in Greensboro to Interstate 95 in Dunn.

Interstate 795 (Florida)

Florida State Road 9B is planned to be redesignated Interstate 795 (I-795) when the designation is approved by the Federal Highway Administration (FHWA) and the American Association of State Highway and Transportation Officials (AASHTO).

Interstate 905

Interstate 905 in California is proposed to replace California State Route 905, which connects San Diego to the Mexican border.
