ROAD WORK NEXT XX MILES Sign Requirements
This guide summarizes the MUTCD requirements and practical application guidance for the G20-1 ROAD WORK NEXT XX MILES sign. Use this resource to understand when it is required, how to place it correctly, and how to maintain clear visibility for safe operations.
When It Is Used
Beginning of long-duration or corridor work zones
Where It Applies
Beginning of the work zone (advance/upstream).
Placement Basics
Mount at the standard height and setback for the roadway with clear sight lines.
Visibility / Reflectivity
High reflectivity and clear sight lines are essential day and night.
1. When a ROAD WORK NEXT XX MILES Sign Is Used
Informs drivers of the total length of a work zone, telling them how many miles of road work to expect ahead.
- Beginning of long-duration or corridor work zones
- Highway and expressway projects spanning miles
- Paired with END ROAD WORK at the downstream end
2. How and Where It Applies
In the field, G20-1 Road Work Next XX Miles is typically positioned at the beginning of the work zone (advance/upstream). Common deployments include beginning of long-duration or corridor work zones; highway and expressway projects spanning miles; paired with END ROAD WORK at the downstream end. 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 G20-1 beginning of the work zone (advance/upstream).
- 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" × 24".
- 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 start of longer California work zones, especially on highways and corridors, to set driver expectations for an extended work area.
Go to California Notes6. Common Field or Planning Mistakes
- 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.
