US 183
U.S. Highway 183 is a north–south United States Numbered Highway that extends from the coastal plains of Texas through the Great Plains to central South Dakota. The route connects a sequence of regional hubs, rural counties, and transportation corridors, intersecting with multiple federal and state highways and traversing diverse landscapes such as the Gulf Coast plain, the Permian Basin, the Llano Estacado, and the Nebraska Sandhills. Initially commissioned in the 1920s as part of the original United States Numbered Highway System, the route has undergone successive realignments tied to the development of the Interstate Highway System, the expansion of regional economies centered on petroleum, agriculture, and urban growth in metropolitan areas such as Austin, Abilene, and Sioux Falls.
Route description
US 183 begins near Refugio in Refugio County, Texas and proceeds northward through coastal and south Texas counties including Goliad County, Texas and Bee County, Texas. It bypasses and serves towns such as Beeville, Texas, intersects with U.S. Route 77 and U.S. Route 59 corridors, and advances toward the Austin metro. Within the Austin region the highway forms arterial connections with Interstate 35, U.S. 290, and state routes crossing the Travis County, Texas urban grid near Round Rock, Texas and Pflugerville, Texas. North of Austin, US 183 traverses the Texas Hill Country and the Edwards Plateau, linking Lampasas, Texas and Goldthwaite, Texas before reaching the Cross Timbers and western Fort Hood. Entering Abilene, Texas, the highway intersects Interstate 20 and concurrent corridors with U.S. 84 and U.S. 277.
Continuing into Oklahoma, US 183 serves towns including Altus, Oklahoma and meets U.S. 62, U.S. 64, and U.S. 70 while crossing the Red River basin. In Kansas, the highway passes through rural counties and links with arterial routes such as U.S. 56, U.S. 54, and Interstate 70 near Hays, Kansas. Through Nebraska, the alignment moves across the Sandhills with junctions at U.S. 20 and U.S. 183-adjacent state highways, before entering South Dakota and terminating near Presho, South Dakota where it meets U.S. 18 and regional connectors to Pierre, South Dakota and Rapid City, South Dakota.
History
The original 1926 designation placed the route within the early United States Numbered Highway System, linking southern Texas to northern plains travelways. Over decades, federal and state transportation agencies such as the American Association of State Highway and Transportation Officials oversaw rerouting tied to corridor improvements near Austin, Texas, the relocation of termini associated with I-35 construction, and alignment exchanges with U.S. 87 and U.S. 385. The postwar era and the rise of the Interstate Highway System prompted truncations and concurrencies with I-20, I-40-area corridors, and the creation of bypasses around urban centers like Abilene, Texas and Hays, Kansas.
Major historical developments include upgrades to divided highways in parts of the Austin metro during the late 20th century, designation changes reflecting regional economic shifts during the 1970s energy crisis and the North American oil booms, and preservation actions by state departments such as the Texas Department of Transportation and the South Dakota Department of Transportation to maintain continuity. Federal funding initiatives related to NHS and corridor planning influenced realignments and safety improvements, while local municipalities including Travis County, Texas and Lyon County, Kansas engaged in intersection redesigns and access management.
Major intersections
Key junctions along the route include interchanges and crossings with U.S. 77, I-35, U.S. 290, U.S. 84, I-20, U.S. 62, U.S. 56, I-70, U.S. 20, and U.S. 18. Additional notable intersections occur at regional connectors including SH 29, SH 21, 183A auxiliary segments, and state-managed junctions serving Fort Hood, Parker County, Texas, and Lyon County, Kansas population centers.
Business routes and special designations
Several business loops and spur alignments have been created to serve downtown districts and historic main streets in municipalities such as Lampasas, Texas, Hays, Kansas, and McCook, Nebraska. Special designations include scenic or historic signage in parts of the Nebraska Sandhills and commemorative namings enacted by state legislatures honoring local figures and events, coordinated with agencies like the Texas Legislature and the Kansas Department of Transportation. Controlled-access bypasses and tolled auxiliary routes in the Austin metro—notably the toll-managed 183A—provide higher-capacity alternatives to surface alignments and interact with regional toll authorities.
Traffic, maintenance, and future projects
Traffic volumes vary from low-density rural flows in South Dakota and Nebraska to high-demand urban corridors in Travis County, Texas and Williamson County, Texas. Maintenance responsibilities are distributed across state departments including the Texas Department of Transportation, the Oklahoma Department of Transportation, the Kansas Department of Transportation, the Nebraska Department of Transportation, and the South Dakota Department of Transportation. Ongoing and proposed projects range from interchange modernization near Austin–Bergstrom Airport and capacity enhancements around Round Rock, Texas to pavement rehabilitation across the Kansas plains and bridge replacements spanning waterways such as the Red River of the South. Federal and state funding sources include Federal Highway Administration programs and state capital improvement plans, with public-private partnership discussions emerging for corridor upgrades linked to freight movements and regional development plans such as metropolitan planning organization proposals in Austin–Round Rock–San Marcos metropolitan area.
