A23

Upgrade of the existing dual two-lane route to dual three-lane standard, along with improvements to junctions and local accesses. The work will be carried out within the existing road boundaries. This scheme will leave Sayers Common to Pyecombe as the only remaining two-lane section between Brighton and the M23.

A new single carriageway three-lane road, realigning the A23 away from the main commercial area of Coulsdon, though the new road still passes through the town. It will terminate at a roundabout at each end, and along its length will have a normal traffic lane in each direction plus a special purpose bus, cycle and HGV lane northbound. This was one of the only road schemes approved by anti-car London mayor, Ken Livingston.
