M25 Berry Lane Viaduct

Construction Works

The Highways Agency has carried out construction works on the Berry Lane Viaduct to allow widening of the M25 to 4 lanes in each direction.

Site clearance included thinning out young trees adjacent to the viaduct. Mature trees at the edge of the working area were retained where it was safe to do so. Re-planting took place at the viaduct abutments.
