Tuolumne County, CA…The California Department of Transportation (Caltrans) is preparing to begin construction to replace 162 feet of culvert on State Route 49 between Sonora and Tuttletown. The project is scheduled to begin the week of August 26, 2024, and end in late September. It will require one-way traffic control between Flume Road and Mt. Brow Road with expected 5-10 minute delays. Residents in the area can expect intermittent construction noise.

To reduce the number of working days and impact on traffic, crews will work 24-hour shifts during the first week of construction. Daytime work will begin the week of September 2 and occur Mondays through Thursdays from 6:00 a.m. until 6:00 p.m. and Fridays from 6:00 a.m. until 4:00.

Flaggers and changeable message signs will alert motorists to the closures and a pilot car will be used to guide motorists safely through the work zone.

Culverts are drainage systems underneath California’s Highway System that channel stormwater to prevent roadbed erosion and reduce the risk of flooding.  This estimated $221,890 project is being performed by Moyle Paving, Inc. of Jamestown, CA.

Schedules are subject to change depending on traffic incidents, weather, equipment and materials availability, and other construction-related issues.
