HC Deb 28 June 1965 vol 715 c1W
7. Dr. Bennett

asked the Minister of Land and Natural Resources what steps he is taking, in view of the new motorways now being completed, to ensure that Ordnance Survey maps on sale to the public are kept up to date in this respect; and when the appropriate sheets will be on sale which will show the whereabouts of the new Chiswick-Slough section of the M.4.

Mr. Willey

The Ordnance Survey is aiming to issue each year a new edition of the 10 mile Route Planning Map containing up to date information about new motorways including those under construction. Similar information is incorporated on the one-inch and quarter-inch sheets as soon as reprints or new editions can be justified.

The Chiswick-Slough section of the M.4 already appears on the South sheet of the 1965 edition of the Route Planning Map. It will be shown on the new edition of one-inch sheet 170 to be published later this year, and on a new edition of the quarter-inch sheet 17 to be published during 1966.
