Large vehicles prohibited on Mockingbird Canyon Road while storm damage is repaired
Update: The box culvert structure has been stabilized, and the 7 ton commercial vehicle weight restriction has been lifted. Repair work will continue at this location with possible temporary closures or flagging.
Trucks, school buses and other commercial vehicles that exceed seven tons will be prohibited for two to four weeks on a section of Mockingbird Canyon Road, near the City of Riverside, because of damage caused by recent storms.
Emergency construction crews yesterday (3/15) began repairing an undermined box culvert beneath the road, approximately seven-tenths of mile south of Van Buren Boulevard. Commercial vehicles weighing more than seven tons will be prohibited during the repairs. Other traffic may continue to use the road but motorists might consider the following alternate routes because of potential delays:
From Van Buren Boulevard, head south on Washington Street and turn right on Harley John Road.
From El Sobrante Road, turn left on Cajalco Road and then left on Harley John Road and transition to Washington Street, and proceed to Van Buren Boulevard.
Safety crews with flags will be directing traffic between 6 a.m. and 6 p.m. on weekdays and weekends. While the project is expected to last two to four weeks depending on the weather, traffic could be restricted further or prohibited entirely if another storm causes concern about more damage.
Riverside County engineers are continually monitoring the culvert to make sure the road is safe for vehicle traffic. In the event the culvert is deemed unsafe for vehicular traffic, the road will be immediately closed for public safety. If the road is closed, we will immediately notify emergency responders, service providers and the media of the closure duration.
