asked the Minister of Transport how many proposals have been put forward by local authorities for building underpasses at busy traffic junctions instead of roundabouts or other crossings at the same level.
I have not received any proposals by local authorities for dealing in this way with existing traffic junctions, although I understand underpasses are contemplated in connection with some schemes of future road or bridge construction. I have plans for four underpasses at junctions on trunk roads.
Does the right hon. Gentleman agree that this form of traffic junction is about the best for ensuring the least possible amount of congestion, and will he do everything possible to encourage local authorities to adopt it?
The fact that I have indicated that we have four schemes under consideration on trunk roads shows our interest in this type of underpass, but every case must be considered on its merits. A very important aspect at present is that of cost.
