When temporary works occur on the highway the needs of visually impaired and disabled people must be kept in mind. Protection of visually impaired people will require the road works to be guarded on those sides accessible to the public.
Barriers must be used to delineate the works and warn pedestrians of their
presence. Barriers are also used to protect pedestrians if the works require
them to be diverted into a hazardous situation.
Pedestrian barriers should be red and white with vertical posts coloured red.
Base supports should not protrude more than 300mm into the path of pedestrians
and any vertical edge should not be more than 25mm high. They should also be
reflectorised or illuminated internally or externally during the hours of darkness.
The lower barrier must be no less than 150mm from the ground and the top barrier
should be between 1000mm and 1200mm from the ground. The bottom barrier must
be sturdy enough to act as a tapping rail for visually impaired people. It will
also prevent guide dogs from walking beneath the top barrier.
Barriers alongside deep excavations should be more substantial, able to withstand
crowd pressure, and at least 300mm clear of the edge of the excavation. They
should meet BS 6399: Part 1 1984, Design Loads for Buildings.
Where the footway is diverted into the carriageway it will be necessary to
provide a safety zone between the outer pedestrian barrier and the live traffic.
The outer edge of the safety zone should be delineated by traffic cones or cylinders.
The inner edge of the safety zone should be delineated by a lightweight barrier.
Temporary signs on the footway should not obstruct vehicles or pedestrians.
The absolute minimum footway width remaining adjacent to the sign should be
900mm. However, it is preferable for the sign to be completely clear of the
footway.
On any section of the road, works should be phased so that only one footway
is disrupted at any one time.
Where a temporary footway is provided, its surface must be of an adequate standard.
Fine grained compact material, Tarmac or well secured timber planking are acceptable
- unbedded flagstones or loose hard-core are not. Ramps must be provided where
a temporary footway is diverted across the kerb, including bellmouths at street
ends (see 6.2 Ramps). A temporary alternative
facility must be provided to replace any ramped access that may be broken up
or obstructed.
