One-Way Traffic Control on Marsh Creek Road (MCR)

Contra Costa County Public Works to Install Traffic Control as part of the Marsh Creek Road Bridges Replacement Project

(Updated) August 4, 2023, Clayton and Brentwood, CA – The Contra Costa County Public Works Department will install one-way traffic control on Marsh Creek Road from approximately 1.3 miles northwest of Deer Valley Road near the Clayton Palms Community to approximately 0.6 miles west beginning on Monday, August 14, 2023, through April 2024, barring unforeseen circumstances. 

The traffic control will include installing a temporary traffic signal system to allow one direction of traffic at a time through the Marsh Creek Road Bridges Replacement Project work area for the public’s safety. Message boards and signage will alert drivers about the traffic control. Drivers should expect delays up to 15 minutes.

The project will replace two (2) bridges on Marsh Creek Road with two (2) new concrete bridges. Work will take place on Marsh Creek Road at Bridges 143 and 145. Bridge 143 is located approximately 1.5 miles northwest of Deer Valley Road near the Clayton Palms Community. Bridge 145 is located approximately 3.0 miles east of Deer Valley Road near the road transition to Camino Diablo. Work also includes reconstruction of the bridge approach and construction of drainage facilities. The temporary traffic signal system to allow one direction of traffic will be installed at the Bridge 143 site only.

Funding for this project is provided by the federal Highway Bridge Program and local Gas Tax funds. To learn more about this project, please visit: www.contracosta.ca.gov/MCR-Bridge
