HC Deb 24 February 1972 vol 831 cc357-8W
Sir C. Bossom

asked the Secretary of State for the Environment what are the criteria applied to decide whether new roundabouts should be provided at road junctions on trunk and principal roads; and in what circumstances it is considered appropriate to provide flyovers or underpasses.

Mr. Michael Heseltine

The type of junction to be adopted is determined by overall consideration of traffic flow, safety, land use, cost and environmental aspects. Advice on this complex matter is given in the H.M.S.O. publications "Layout of Roads in Rural Areas" and "Roads in Urban Areas".

Sir C. Bossom

asked the Secretary of State for the Environment in how many cases plans for improvement of road junctions on trunk and principal roads provide for the construction of new roundabouts and for the construction of flyovers and underpasses.

Mr. Michael Heseltine

This information is not readily available and it would be very costly and time consuming to assemble.
