U.S. 14

U.S. 14

U.S. 14 runs from the East Entrance of Yellowstone National Park in Wyoming east to U.S. 41 (Lake Shore Drive) in Chicago, Illinois. Within South Dakota, U.S. 14 runs in tandem with I-90 through Spearfish, Sturgis, Rapid City and Wall. The route separates from the freeway at Exit 112 for Philip, the capital city of Pierre, Highmore, Miller, Huron, De Smet and Brookings. There is an Alternate U.S. 14 between Spearfish and Sturgis via Spearfish Canyon, Lead and Deadwood. A 5.1 mile Bypass route for U.S. 14 is also posted around Brookings and the campus of South Dakota State University (SDSU).

U.S. 14 was not one of the original 1926 Wyoming U.S. Routes. The highway was designated to end at U.S. 16 in Wall, South Dakota, at that time. The route was extended in 1936 via Rapid City, Spearfish and Sturgis to enter Wyoming. U.S. 16 was rerouted through Custer and Newcastle, while the old U.S. 16 became the new U.S. 14. From 1936 today, U.S. 14 has roughly maintained the same course between Burgess Junction, Wyoming and Wall, South Dakota, with exceptions of old alignments bypassed by construction of Interstate 90 in the 1960s and 1970s. Noteworthy is the old U.S. 14 loop through Rapid City, which is now served by Business Loop I-90.
