Joshua Tree National Park, in cooperation with the Central Federal Lands Highway Division of the Federal Highway Administration, will begin construction of approximately 10 miles of Park Route 11 (Pinto Basin Road) on Monday, February 10, 2014. The primary objective of the project is to improve safety conditions for the Pinto Basin Road. 

The proposed action would include widening, realigning, and modifying the existing 20- to 22-foot-wide paved road to a 24-foot- wide road, with a design speed of 35 or 45 miles per hour. It would also redesign and realign the road to improve sight distances and safety at the Porcupine Wash area and the site south of the Cottonwood Visitor Center. The construction will result in travel delays of up to thirty minutes. The proposed action is part of a phased effort to rehabilitate many of the park’s primary roadways in accordance with the 1995 Joshua Tree National Park General Management Plan.

Any questions regarding this project can be directed to, Kirk Diamond, Chief of Maintenance, Joshua Tree National Park, 760-367-5680, or Roads Supervisor, Jeremie Johnston at 760-367-5683.
