§ Mr. Rookerasked the Secretary of State for the Environment on what date the experimental short length of surfacing was laid on the Ml near Watford ; and if he will make a statement on the result of the experiment.
§ Mr. CarmichaelThe length on Ml near Watford Gap was laid in September 1973. I should also inform my hon. Friend of a second short length laid on Ml, near Junction 28, in September 1974. It is too early to obtain results from either of these trial lengths.
