M2 J5 Improvements

Scheme outline

Improvements to M2 junction 5 (Stockbury) which is a major interchange with the A249. At present the junction suffers regular congestion, particularly on the A249 southbound and the exit from the M2 westbound, and has an extremely poor safety record. It forms a break in the otherwise free-flowing A249 between Maidstone and Sheppey. Planned developments in the area will put further pressure on the junction.

Highways England initially proposed improvements to the sliproads and roundabout, but a more ambitious design was selected as the preferred route. A flyover will be built to carry the A249 over the roundabout, and some local roads will be diverted around the outside of the junction. Some left turns at the roundabout will be made free-flowing.

The M2 and its sliproads will not be modified, except where the sliproads interface with the upgraded roundabout junction.
