 across the pedestrian access to the crossing and a "CROSSING NOT IN USE" sign to diagram 7016 to warn pedestrians must be provided. See Section D325 and Part 2: Operations, Section O3.13 and O3.14.

In cases where it is proposed to place barriers across crossing areas, consideration must be given to the provision of nearby drop kerb arrangements so as not to create problems for physically impaired users, pedestrians with pushchairs etc.

If double white lines are to be obliterated because of road works and cannot be replaced quickly, a temporary order restricting overtaking should be made and temporary "no overtaking" signs to diagram 632 erected. See Chapter 3 of the Traffic Signs Manual for advice on siting these signs.

It is important to remove any lengths of road markings which are in conflict with temporary traffic requirements, for example, when vehicles would otherwise have to pass over raised rib lines at changeover and crossover positions or chevron markings atjunctions, or when two or more parallel lanes of traffic are changing lanes. However, raised rib and other lane markings may be left in-situ, where they match with the temporary lane markings.

There should be no need to remove or cover the lane markings at a changeover position when only one lane is being switched. However, edge of carriageway markings are generally raised rib lines and so should be removed. For works for which relaxations apply, following a risk assessment, the hard shoulder/lane 1 raised rib marking may be retained at the changeover.

Where positive traffic control is necessary at road works, the following signs may be used:

Manually operated “STOP” and “GO” signs to diagrams 7023 and 7024. See Section D5.8 for guidance on the length/flow characteristics of this type of control. It should not be operated over distances greater than 500m. These signs are not to be used at night unless the signs are directly illuminated. When a frame is used to support the sign this should be circular, not octagonal, as both signs are mounted on a circular substrate.

As with fixed signs, illumination shall be uniform across the sign face and shall be steady. Partial illumination of sign faces is not permitted, nor is intermittent illumination. 85
