What This Sign Means
Informs drivers of the total length of a work zone, telling them how many miles of road work to expect ahead.
California Temporary Traffic Control Use
Used at the start of longer California work zones, especially on highways and corridors, to set driver expectations for an extended work area.
Common TCP Context
- Beginning of long-duration or corridor work zones
- Highway and expressway projects spanning miles
- Paired with END ROAD WORK at the downstream end
California Size Requirements
Typical minimum: 48" × 24".
Sizes are CA MUTCD minimums and vary by roadway classification and speed. Verify against the CA MUTCD 2026 (CA MUTCD Part 6, Chapter 6F (Temporary Traffic Control)), Caltrans sign specifications, and the reviewing agency.
Common Placement on a TCP
Where it sits: Beginning of the work zone (advance/upstream).
CA MUTCD reference: CA MUTCD Part 6, Chapter 6F (Temporary Traffic Control).
Los Angeles Area Usage Notes
In Los Angeles, this sign must conform to CA MUTCD 2026. Work in City of LA right-of-way is reviewed by StreetsLA and the Bureau of Engineering (BOE); state highways in LA County are permitted and reviewed by Caltrans District 7; county roads are permitted by LA County DPW. Sizes, retroreflectivity, and placement must meet CA MUTCD minimums — local agencies may require larger signs based on roadway class, speed, pedestrian volume, and proximity to schools or transit.
Common Plan Review Comments
- Stated work-zone length does not match the actual work limits.
- END ROAD WORK missing or placed before the termination area.
- Wrong size specified for the facility.
- Sheeting / retroreflectivity class not noted.
Plan Review Notes
Confirm the stated distance matches the actual work limits and that END ROAD WORK closes the zone. Public Ready reviews work-zone limits signing.
