1. When roads are temporarily closed to public access, barricades or gates must be used that are highly visible in day or night conditions. At a minimum, barriers must be coated with reflective paint or be applied with highly reflective tape on both sides, and be signed as "ROAD CLOSED".
2. Affected roads must also be posted with appropriate warning signs a minimum of 100 ft (30.5 m) before the barrier per W20-3, DNG-11, W RN-24, or other appropriate signs from the MUTCD or USACE Sign Standards Manual. Size and placement of signs depends on viewing distance and speed limit of roadway.
