closed

Limits: Thousand Palms Canyon Rd, between Ramon Rd/Washington St and Dillon Rd Length: 4.71 miles The Riverside County Transportation Department proposes to widen and resurface Thousand Palms Canyon Rd, between Ramon Rd/Washington St and Dillon Rd, in the Thousand Palms area of Riverside County. Thousand Palms Canyon Rd is a 2-lane collector that travels in the North-South directions. Existing pavement width is approximately 22’ wide with 11’ through lanes and a 1’ paved shoulder. There is graded dirt shoulder of varying width along both sides of the road bounded by dirt berms. There is a half-mile segment of Thousand Palms Canyon Rd adjacent to the Coachella Valley Nature Preserve that is 32’ wide, with 12’ through lanes and 4’ paved shoulders, with graded shoulders bounded by dirt berms. The area in the immediate vicinity is undeveloped. The project scope includes pavement widening and resurfacing, constructing pavement transitions, constructing Safety Edge pavement end condition, installing rumble strips, widening paved shoulders, grading dirt shoulders, grading dirt berms, installing and removing signs, and applying traffic striping and thermoplastic pavement markings. The new pavement width will be 34’ wide, with two 12’ through lanes and 5’ paved shoulders. A new right-turn pocket will be constructed at the Coachella Valley Preserve entrance. A new left-turn pocket and driveway will be constructed approximately one half-mile north of the nature preserve.
