HC Deb 27 March 1995 vol 257 cc506-7W
Mr. Key

To ask the Secretary of State for Transport if he will list the location, length in metres and cost of all road tunnels(a) constructed by his Department in each of the past 10 years and (b) proposed for construction in future with estimated cost. [15681]

Mr. Watts

This is an operational matter for the Highways Agency. I have asked the chief executive to write to my hon. Friend.

Letter from Lawrie Haynes to Mr. Robert Key, dated 27 March 1995: As you know, Mr. John Watts, the Minister for Railways and Roads has asked me to reply to your Parliamentary Question asking the Secretary of State for Transport, if he will list the location, length in metres and cost of all road tunnels (a) constructed by his Department in each of the past 10 years and (b) proposed for construction in future with estimated cost. This is attached. You will understand that any simple cost comparisons, based on tunnel length, could be very misleading given the many differing factors which will apply in each case—tunnel location (urban/rural region), geological and groundwater conditions, total lane width and construction method (bored NATM or cut and cover etc).
