In 2014, the Palm Springs Desert Sun newspaper reported that a dozen marines from the Marine Corps Air Ground Combat Center Twentynine Palms have been killed in accidents on Highway 62 since 2007 (out of a total of 33 vehicle-related deaths among personnel at the base); the paper attributed the problem in part to the base's unusually remote location, leaving personnel few options for entertainment.[3]
SR 62 is part of the California Freeway and Expressway System,[4] and west of the military base is part of the National Highway System,[5] a network of highways that are considered essential to the country's economy, defense, and mobility by the Federal Highway Administration.[6] SR 62 is eligible for the State Scenic Highway System,[7] and is recognized by Caltrans as a scenic highway for 9 miles (14 km) from its western terminus at I-10 to the Riverside–San Bernardino county line,[8] meaning that it is a substantial section of highway passing through a "memorable landscape" with no "visual intrusions", where the potential designation has gained popular favor with the community.[9] SR 62 is designated as a Blue Star Memorial Highway from Interstate 10 to Adobe Road in Twentynine Palms. SR 62 is known as the Twentynine Palms Highway from I-10 to SR 177.[10]
History
The routing west of Twentynine Palms was added to the state highway system in phases, with the part from White Water to Morongo Valley added in 1935, and from Morongo Valley to Yucca Valley in 1959; both were designated as Route 187.[11][12] From Yucca Valley to Twentynine Palms, Route 218 was added in 1961.[13] In the 1964 state highway renumbering, SR 62 was designated from I-10 into the town of Twentynine Palms.[14] The portion from Twentynine Palms to Arizona was added to SR 62 in 1970.[15]
Major intersections
Except where prefixed with a letter, postmiles were measured on the road as it was in 1964, based on the alignment that existed at the time, and do not necessarily reflect current mileage. R reflects a realignment in the route since then, M indicates a second realignment, L refers to an overlap due to a correction or change, and T indicates postmiles classified as temporary (for a full list of prefixes, see California postmile § Official postmile definitions).[1] Segments that remain unconstructed or have been relinquished to local control may be omitted. The numbers reset at county lines; the start and end postmiles in each county are given in the county column.
