The Project
This scheme forms a part of the Highways Agency's existing strategic roads programme. The M25 is one of the busiest routes in England, the upgrades to this part of the motorway are vital in tackling congestion and improving the journey time and reliability to the road user.
In July 2003 the Highways Agency were asked to develop a phased programme for widening the remaining 3 lane sections of the M25 to dual 4 lanes over the next decade.
This section of the M25 includes motorway connections from the Dartford Crossing and the M20.
The Highways Agency announced in April 2004 that it would develop proposals for widening the M25 between Junctions 1b and 3.
The proposals included:
- Widening the M25 to 4 lanes between the south facing slip roads of Junction 2 and the north facing (M20) slip roads of Junction 3.
- Widening the southbound M25 to 3 lanes from Junction 1B to south of Junction 2.
- No land take from outside the current limits of the M25.
- Low noise road surfacing and/or noise fencing to shield properties and to reduce traffic noise.
- Improved drainage pollution measures to trap spillage from the highway and prevent contamination of water courses.
Start of Works
Work began on widening junctions 1b to 3 of the M25 on 11th June 2007 and was completed on 22 July 2008 with communications and signalling work continuing until early 2010.
