HC Deb 20 April 1989 vol 151 cc266-7W
Sir Richard Body

To ask the Secretary of State for Transport what assessment he has made of whether the junction of the A 17 road with the A151 is adequately illuminated at night.

Mr. Peter Bottomley

We considered the provision of lighting carefully during preparation of the A17 New Washway road scheme. Lighting is both expensive and intrusive and can be justified only where it is expected to make a significant contribution to road safety. The provision of lighting to the west of Boston road roundabout, including the A151 link road junction, could not be justified.

We do not normally light isolated junctions in rural areas except as part of a larger system. Isolated clusters of lights can be dangerous because switching from darkness to light and back in quick succession can disorientate drivers on the main road. The proper way to warn drivers of a junction is by adequate signing. This has been done.
