HC Deb 06 November 1978 vol 957 cc84-5W
Mr. Pardoe

asked the Secretary of State for Transport what estimate he has made of the damage done to motorways by vehicles of different axle weights.

Mr. Horam

Research is continuing to establish the damaging effects of vehicles of different axle weights and configurations.

Mr. Pardoe

asked the Secretary of State for Transport what is the estimated cost of repairs to motorways and trunk roads, respectively, in the current financial year; and how much of this has been made necessary by cars and how much by heavy lorries.

Mr. Horam

The estimated cost of repairs to motorways and other trunk roads in the current financial year is:

Motorways £24.0 million
Trunk roads £29.4 million

Costs cannot be apportioned between cars and heavy lorries as damage can take several forms and traffic composition varies on different routes.
