U.S. Route 35 (US 35) is a major north–south and east–west corridor in the eastern and midwestern United States, serving as a vital connector between the Ohio River Valley and the Great Lakes region. Stretching approximately 412 miles, the highway begins in northern West Virginia and traverses through Ohio before terminating near Michigan. Uniquely, US 35 runs in a diagonal fashion and is one of the few U.S. highways to lack any directional suffix, despite serving both east–west and north–south functions in various segments.
Starting in Scott Depot, West Virginia, US 35 travels northwest, crossing the Ohio River via the Silver Memorial Bridge into Gallia County, Ohio. In Ohio, the route becomes an expressway for most of its length, passing through cities such as Jackson, Chillicothe, and Dayton. US 35 intersects with several major routes, including US 23, US 50, and Interstates 71, 75, and 675, making it a strategic route for both freight and passenger travel. The Ohio segment, in particular, has undergone numerous upgrades to improve safety and capacity, with many rural segments now functioning as four-lane divided highways.
US 35 concludes at an interchange with Interstate 90 and State Route 931 near La Porte, Indiana, just south of Lake Michigan. While not as nationally prominent as other U.S. highways, US 35 plays a crucial regional role by linking industrial, rural, and metropolitan areas. Its improvements over the years have made it a faster and more reliable alternative to older local roads, especially for cross-state travel between West Virginia and Indiana.
