STREET CLOSED Sign Requirements

1. When a STREET CLOSED Sign Is Used

Indicates that a street is closed to traffic, used to legally close a local street for work or an event.

• Permitted local-street closures
• Placed at the closure with advance closure signing
• Used with barricades (Type III) across the street

2. How and Where It Applies

In the field, R11-2a Street Closed is typically positioned at the at the closure point (activity area), typically on a barricade. Common deployments include permitted local-street closures; placed at the closure with advance closure signing; used with barricades (Type III) across the street. Always confirm its size, retroreflective sheeting, spacing, and placement against the CA MUTCD 2026 and the reviewing agency before finalizing the traffic control plan.

3. Placement and Application Notes

Position R11-2a at the closure point (activity area), typically on a barricade.

• Place the sign where drivers have a clear, unobstructed view on approach.
• Mount at the standard height and setback from the edge of the traveled way.
• Do not mount with other signs on the same post unless space constraints require it.

4. Standard Sizes and Visibility Considerations

Typical minimum: 48" × 30".

• Choose size based on roadway speed, sight distance, and mounting location.
• Maintain high retroreflectivity for maximum night and adverse-weather visibility.

5. California Notes

Used at the point of a permitted local-street closure in California, in place of ROAD CLOSED where STREET is the appropriate legend, with an authorizing encroachment permit.

6. Common Field or Planning Mistakes

• Closure limits on the plan do not match the approved permit exactly.
• Closure not backed by advance warning and a signed detour.
• Local-access provisions unclear (especially for ROAD CLOSED TO THRU TRAFFIC).
• Barricade type (e.g., Type III) not specified.
