The Uinta Basin Rail project is a proposed 100-mile (160 km) rail line to connect the shale oil rich Uinta Basin region of eastern Utah to the national rail network. Numerous proposals have been made, some as far back as 1902, that are still under consideration. The current effort is a public-private partnership between a coalition of 7 counties in Utah, the Rio Grande Pacific Corporation and Drexel Hamilton Infrastructure Partners. The railroad is also backed by the Ute Tribe who hold a 5% stake in the project. If the rail line is built it will be the first major greenfield rail line built in the United States since the line to the Powder River Basin was built in the 1970s. The Surface Transportation Board approved construction of the line in December 2021.
