Clayton Road signing/signal changes combat cut-through traffic

At the request of local residents, the City of Concord plans to put measures in place to reduce the number of non-resident vehicles traveling from Clayton Road through neighborhoods located near Treat Boulevard during the weekday morning commute period, 6:30 to 9 a.m. Monday through Friday.

Beginning Monday, March 6, new signage posted on Clayton Road will prohibit westbound left turns and/or eastbound right turns at the following intersections during morning commute hours: La Vista Avenue, Cape Cod Way, Bel Air Drive and Marclair Drive.

At several signalized intersections, the amount of green time allocated for the westbound left turn/U-turn movements would be reduced during the same hours and advisory signs will be installed notifying motorists of the limited left turn green time. The reason for limiting the left turn/U-turn green time is to discourage high volumes of cut-through traffic from turning onto residential side streets, but allow time for low volumes of local residents to access the neighborhood at these intersections. These intersections include Farm Bureau Road, West Street, and Rosal Lane/Mendocino Drive.

Drivers are cautioned not to trust GPS-based geographical navigation apps and abide by the new signage at the intersections, as the changes will not immediately be available on the apps.

The City thanks residents for their cooperation in implementing this new program, and anticipates safer neighborhoods due to less cut-through traffic. For more information, contact Ray Kuzbari, Transportation Manager at (925) 671-3129 or via email at
