§ Sir Clive Bossomasked the Minister of Transport if he will provide details of the electronic warning systems that have been erected on motorways during the past six months, and also provide the future electronic warnings programme which is planned on all motorways.
§ Mr. MarshThe first of the remotely controlled signal systems for motorways was brought into use on a three mile section of the M4 (on the Severn Bridge) last June. The second on the Metropolitan section of the M4 between Chiswick and Langley is now being installed and should be in service early next year.
The contract for the system for the West Riding motorways is about to be let and I shall shortly invite tenders for the system for the M6 in Lancashire.
Design of the systems for the southern end of M1 and the Midland Link motorways is in hand and I hope to complete 37W the programme of 1,000 miles of warning systems by the mid 1970s.
The signals shown to drivers by these systems are generally as described in the announcement made on 16th November, 1966.
