HC Deb 21 March 1977 vol 928 c372W
Mr. Fitch

asked the Secretary of State for Transport what estimate he has made of the benefits of new road building to industry and commerce.

Mr. William Rodgers

It has been estimated that the savings in working time alone provide a return on investment of about 8 per cent-10 per cent. in real terms for a typical trunk road scheme. This is in addition to savings in nonworking time and accidents, and represents a direct increase in productivity for industry and commerce.
