§ 68. Mr. Swinglerasked the Minister of Transport if he will specify the parts of the M.6 motorway where changes have been made in the carriageway sub-base materials at an extra cost of £900,000.
§ Mr. MarplesAfter the original specifications for the Lancashire and Staffordshire sections of the M.6 were prepared, the standard carriageway specification for motorways was improved in order to reduce deterioration under heavy traffic. These improvements were adopted in Lancashire and Staffordshire over a total length of 37 miles at an extra cost of about £693,000. In Cheshire a change of material to facilitate construction work has increased costs by about £200,000.
