HC Deb 26 April 1972 vol 835 c281W
45. Mr. Raphael Tuck

asked the Secretary of State for the Environment why he proposes to extend the existing four-lane carriageway on the M1 between Watford and Hemel Hempstead into an eight-lane carriageway, instead of making it a six-lane carriageway and thus uniform with those parts of the M1 south of Watford and north of Hemel Hempstead.

Mr. Speed

This stretch of the M1 is heavily overloaded. Traffic information indicates that dual four-lane capacity should be provided now to give a satisfactory economic life.
