Contra Costa County Public Works Pinehurst Road Culvert and Sinkhole Repair Project
(Updated) September 28, 2021, Canyon, CA - Construction of the Pinehurst Road Sinkhole and Culvert Repair Project began on Monday, August 30, 2021. The project is located approximately 2.5 miles northwest of Canyon Road, at the first hairpin turn. Work includes replacing a portion of drainage pipe under Pinehurst Road, as well as improvements to aid in fish passage upstream. Work will also include temporary water diversion and dewatering, stabilizing the embankment using rock slope protection, roadway excavation and reconstruction, establishing a roadside ditch, traffic control and roadway striping and signing. Restrictions are in place to minimize impacts during commute hours. Drivers should expect delays.
The replacement pipe installation and road reconstruction is underway. Due to unforeseen circumstances, the road must remain fully closed through Friday, October 1, 2021 - only emergency vehicles will be allowed access through the work zone during this closure. Other site work will continue after the full closure ends, with intermittent two-way, flagged traffic control for performing the remaining work. Message boards providing notice of the upcoming road closure will be placed near the project site prior to road closure. Road users should expect 10-15 minute delays near the project site due to the need to use alternate routes.
The full-time closure of Pinehurst Road has been extended through Friday, October 1, 2021 with a planned re-opening by Saturday, October 2, 2021. NO PUBLIC TRAFFIC WILL BE ALLOWED THROUGH THE WORK ZONE during this closure. The project is scheduled to be completed by Sunday, October 31, 2021.
Funding for this project is provided by Gas Tax (SB1) funds and Emergency Relief (Federal Highway Administration) Funds. For more information on this project visit: http://www.cccounty.us/pwprojects
