Martinez, CA – Contra Costa County Public Works is addressing road shoulder embankment failures due to previous years of winter storms. Some failures have occurred along Alhambra Valley Road, Bear Creek Road, Marsh Creek Road, Happy Valley Road, Carquinez Scenic Drive, among others.
Marsh Creek Road is closed in both directions, between the Clayton City limits and Morgan Territory Road due to rock and mud slides. We anticipate re-opening the road by early afternoon. Please take alternative routes to avoid this area.
Temporary measures have been implemented to keep the motoring public safe while the roads remain open to traffic. In some cases, temporary concrete barriers have been placed, along with temporary stop signs, to reduce the road to a single lane at the location of the road failure.
Public Works is actively designing a permanent fix to these road failures as well as securing funds to seek environmental clearances and construct the necessary fixes. In some cases, federal and state emergency funds are sought to recover from winter storms declared as disaster areas (as was declared in 2017).
Public Works appreciates the public’s patience as these permanent repairs are planned for and constructed. In the meantime, we will continue to monitor the effectiveness of these temporary measures and asks the public to adhere to the temporary traffic control measures.
