Arrowhead Trail
(Arrow Highway - U.S. Highway 91)Early roads from Los Angeles to Las Vegas did not follow the Union Pacific through the desert because of the hazards of heavy sand and unpredictable water levels in the Afton Canyon area. Instead, the road, graded by the state in 1922, skipped to the north, roughly following the Old Spanish Trail, a wagon road contemporary of the Mojave Road. In 1925, the county realigned the route through Baker. Paved in 1932, the name of the road was changed; originally known as the Arrowhead Trail, the highway was designated U.S. 91. Traffic to and from Las Vegas was substantial after World War II, because of the development of Las Vegas as a resort destination. Constructed very close to the alignment of U.S. 91, Interstate 15 was finished through the area by 1964. Almost all of the small service stations supported by U.S. 91 were destroyed by I-15; those that exist today were built after the freeway was completed through the area.
