§ Mr. Bossomasked the Minister of Transport (1) what investigations have been conducted to assess the advantages, especially the reduction of the risks of accidents at night, which would result from lighting the length of the M.4 motorway between the end of the elevated section and London Airport;
(2) whether lighting will be provided on the length of the M.4 motorway between the end of the elevated section and London Airport;
(3) how much it would cost to provide lighting on the length of the M.4 motorway between the end of the elevated section and London Airport.
§ Mr. Tom FraserConsideration is being given to the provision of lighting on the length of the M.4 motorway between the viaduct section and London Airport. One of the factors involved in this consideration is the possible reduction of accidents at night. The approximate capital cost is estimated to be £125,000.
§ Mr. Bossomasked the Minister of Transport whether remotely-controlled illuminated warning signs will be provided on the M.4 motorway to reduce the risk of accidents in fog.
§ Mr. Tom FraserRemotely-controlled warning signs which can be used to direct traffic from the elevated section of the M.4 in case of fog have already been installed. But I need to await the outcome of the experiment on the M.5 before deciding whether to extend this system to other motorways.
