Road Closure Signs
Regulatory closure signs — road closed, road closed ahead, and road closed to thru traffic — used at and ahead of a California closure.
Road closure signs notify and regulate traffic at a full or partial roadway closure. The regulatory ROAD CLOSED (R11-2) sign is posted at the closure point — typically on a Type III barricade across the roadway — while STREET CLOSED — LOCAL TRAFFIC ONLY (R11-3a) covers closures that keep local access, and the warning sign W20-3 (ROAD CLOSED AHEAD) gives advance notice so drivers can turn or follow a detour.

What is the difference between ROAD CLOSED and ROAD CLOSED TO THRU TRAFFIC?
ROAD CLOSED (R11-2) closes the road to all traffic at the closure point. ROAD CLOSED TO THRU TRAFFIC (R11-4) closes the road to through movement but still allows local access to properties within the closure.
What sign goes on the barricade at a full closure?
The regulatory ROAD CLOSED (R11-2) sign is commonly mounted on a Type III barricade across the roadway at the closure point, with advance warning and detour signing upstream.
Do road closures in Los Angeles require special coordination?
Often, yes. Full closures may require LADOT coordination for signal timing, LA County Metro coordination if transit is affected, and public notice under local ordinance. State highway closures are reviewed by Caltrans District 7.
Is a detour always required for a closure?
A closure should provide a way for affected traffic to continue — either a signed detour for through traffic or clear local-access provisions. The right approach depends on the closure type and the reviewing agency's requirements.
