A.5Warning of a road closure ahead#
Advanced warning of a road closure ahead should be provided. Warning signs (see Figure A.5.1 and A.5.2) may be installed at the start of the road section and may be some distance from actual closure point. They should be installed at decision points, where areas exist to turn around the longest vehicles using that stretch of road or where alternative routes are available. Special arrangements for local traffic to access their properties may need to be considered and the signs adjusted accordingly. Where local traffic is provided access, the ROAD CLOSED signs should be located where the road is closed to all traffic and the ROAD CLOSED AHEAD sign used at the point where only locals should be permitted to travel past.
Where speed limits on approach to a road closure are greater than 60km/h, a 60km/h temporary speed limit must be implemented 300 to 500m in advance of the closure point. A PREPARE TO STOP message may be used 300 to 500m in advance of the closure point.
