§ Sir Clive Bossomasked the Secretary of State for the Environment, in assessing the cost of installing crash barriers on a motorway in use, what allowance is made for the adverse effect on the cost of the vehicle operation as a result of shutting off one lane.
§ Mr. Michael HeseltineNone. As far as possible, work on motorways in use is carried out during off peak periods in short sections with long gaps in between. Any adverse effect on the cost of vehicle operation is considered to be negligible.
