Hindhead tunnel effects

Damian Hinds (East Hampshire, Conservative)
To ask the Secretary of State for Transport pursuant to the answers of 12 July 2010, Official Report, column 467W, on A3, and 6 September 2010, Official Report, column 176W, on A3: Hampshire, what assessment she has made of (a) traffic levels and (b) noise on the A3 between Liphook and Petersfield (i) before and (ii) following the opening of the Hindhead Tunnel; what measurements of traffic levels have been made since the opening of the tunnel; and how the measurements compare to the pre-opening projection of traffic increase.
Michael Penning (Parliamentary Under Secretary of State (Roads and Motoring), Transport; Hemel Hempstead, Conservative)
As indicated in the answer given on 6 September 2010Hansard, column 178W, the section of the A3 between Liphook and Petersfield is outside the area of scope for the A3 Hindhead project. Noise assessments were not made prior to scheme start because the increase in traffic flows are forecast to be less than 10%. Changes in traffic flows of less than 10% will generate noise increases of less than 1dB(A)—the limit to which change in traffic noise can be detected by the human ear.
