US 33

US 33 is a United States Numbered Highway that runs diagonally from northwest to southeast across the Midwestern and Mid-Atlantic regions, connecting urban centers, rural counties, and Appalachian corridors. It links the industrial and transportation hubs of Elkhart and Fort Wayne with the collegiate and manufacturing centers of Columbus and the state capitals and historic cities of Charleston and Richmond. The route serves freight corridors, commuter links, and scenic passages through the Allegheny Mountains, interacting with numerous Interstate Highways, U.S. Highways, and state routes.

Route description

US 33 begins near Elkhart and proceeds southeast through northern Indiana to Fort Wayne, intersecting with I-69, US 20, and US 24 before crossing into Ohio. In Ohio, the highway traverses the agricultural and industrial landscapes of Van Wert County, Allen County and reaches the Columbus metropolitan area where it converges with I-270, US 23, and US 40 (National Road)|US 40. East of Columbus US 33 follows a southeastward corridor through the Hocking Hills region, passing near Lancaster and Logan, then ascends into the Appalachian Plateau and crosses the Ohio River into Huntington and Charleston where it intersects I-64, I-77, and US 119. In Virginia, the route continues through the Shenandoah watershed and the Allegheny Highlands, providing access to Shenandoah National Park, Luray, and the Blue Ridge Parkway vicinity before terminating in Richmond near junctions with I-95 and US 60.

History

The designation was created during the 1926 establishment of the United States Numbered Highway System alongside contemporaries such as US 1, US 30, and US 40. Early routing reflected industrial corridors tied to Pennsylvania Railroad and Baltimore and Ohio Railroad rights-of-way, and the highway fostered connections between manufacturing centers influenced by companies like Studebaker and Delco Electronics. During the New Deal era, federal programs including the Civilian Conservation Corps and Works Progress Administration contributed to bridge and roadside improvements along segments that paralleled projects funded by the Tennessee Valley Authority and other regional initiatives. Postwar growth and the construction of the Interstate Highway System—notably I-70 and I-71—led to realignments as US 33 was upgraded, bypassed, or truncated in places near Cleveland and Pittsburgh corridors. Environmental reviews during the National Environmental Policy Act era affected Appalachian upgrades, intersecting with conservation efforts by organizations such as The Nature Conservancy and federal land management by the National Park Service.

Major intersections

US 33 intersects numerous principal routes and interstates serving regional and national networks, including I-80 via connecting ramps, I-69 at Fort Wayne, I-75 via nearby links in the Toledo–Dayton–Columbus triangle, I-270 around Columbus, US 23 in central Ohio, I-64 and I-77 in West Virginia, and I-95 in Richmond. Other significant junctions include crossings with US 20, US 24, US 35, US 22, US 119, and state routes that connect to county seats such as Lancaster, Logan, Athens, and Huntington.

Future plans and upgrades

State departments of transportation—Indiana Department of Transportation, Ohio Department of Transportation, West Virginia Department of Transportation, and Virginia Department of Transportation—have planned multimodal improvements, corridor studies, and safety projects along the route. Initiatives include interchange modernizations influenced by designs used on I-270 and roundabout installations similar to projects in Lancaster County. Appalachian corridor upgrades coordinate with federal funding programs from the U.S. Department of Transportation and economic development grants administered by entities like the Appalachian Regional Commission. Environmental permitting for mountain segments requires consultation with the U.S. Forest Service and National Park Service when projects approach protected landscapes near Shenandoah National Park and the Monongahela National Forest.

Auxiliary routes and business loops

Multiple business routes and bypasses have been designated to maintain local access and reduce through-traffic in urban cores, including business loops through Columbus suburbs, bypasses around Lancaster and Logan, and truck routes near Charleston. These auxiliary designations coordinate with local jurisdictions such as county governments in Delaware County and Fairfax County and follow patterns established by auxiliary systems like I-270 Spur and historic business routes of US 23 Business. Maintenance and signage adhere to standards promulgated by the American Association of State Highway and Transportation Officials.
