§ Mr. Peter Bruinvels
asked the Secretary of State for Transport why it will take three years to install improved emergency warning signals with automatic incident detection on the M25 motorway.
§ Mrs. Chalker
Automatic incident detection is being provided on the M25 initially within, and on the approaches to, the Holmesdale and Bell common tunnels. Thereafter, it is proposed to extend the facility to the approaches to the Dartford tunnel.
The signal installation programme is currently being reviewed.
