HC Deb 19 March 1976 vol 907 c662W
Mr. Edge

asked the Secretary of State for the Environment whether, in view of the predicted traffic levels at the southern end of the A5(D), he intends to proceed with the construction of a grade-separated interchange at the junction with the H10.

Mr. Marks

Yes. The predicted volumes of crossing and turning traffic at the peak hours in 1995 make a two-level junction necessary. The A5(D) is already elevated to cross the Grand Union Canal and B488 Simpson Road. It is not possible to lower it to ground level before reaching grid road H10 and it would cause too much disruption of traffic to build a bridge under the A5(D) once it was open. It is, therefore, sensible to provide the bridge and junction during the construction of the road.
