HC Deb 28 July 1983 vol 46 c553W
Mr. Robert Hughes

asked the Secretary of State for Transport if he will consider introducing measures to alert road users well in advance, in terms of distance, of motorway roadwork delays so that users can re-schedule or re-route their journeys.

Mr. Tom King

At motorway repair sites where exceptional delays are possible and alternative high standard routes are available, appropriate warning is given well in advance. At other sites, where there is not much delay, it is better for drivers to stay on the motorway. The signing of alternative routes could well involve longer journey times.
