Route description
[edit]
SR 177 begins atI-10nearDesert Centerand briefly travels north, intersecting withCR R2.At this intersection, SR 177 turns northeast and travels across theMojave Desert,through theChuckwalla Valley.It passes near theDesert Center Airportand comes nearPalen Lake,a dry lake. The highway passes along the southeastern boundary ofJoshua Tree National Parkbefore turning due north and crossing the desert for several miles. SR 177 briefly turns northeast again before intersecting withSR 62and defaulting onto SR 62 eastbound.[3]
The route is two lanes wide for its entire length.[4]SR 177 is not part of theNational Highway System,[5]a network of highways that are considered essential to the country's economy, defense, and mobility by theFederal Highway Administration.[6]In 2013, SR 177 had anannual average daily traffic(AADT) of 1,200 at the northern terminus with SR 62, and 3,700 at the southern terminus with I-10, the latter of which was the highest AADT for the highway.[7]
History
[edit]TheMetropolitan Water Districtbuilt a road from Desert Center that ran north before turning east toEarpalong with portions of theColorado River Aqueductfrom February 20 to August 4 in 1933. This was part of a road system that was built in order to support the construction of the aqueduct by connecting the camps that construction workers resided in during the project. This road cost $389,600 (about $7 million in 2023 dollars)[8]to construct; the roads in the system were paved.[9]SR 177 was added to the state highway system in 1972 by theCalifornia State Legislature.[10]As of 1998, Caltrans had no plans to expand the highway, considering it to be "maintain only" through 2015.[4]
Major intersections
[edit]Except where prefixed with a letter,postmileswere measured on the road as it was when the route was established, 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 ().[1]Segments that remain unconstructed or have been relinquished to local control may be omitted. The entire route is inRiverside County.
