M25 junction 8: junction improvement
Improving junction 8 of the M25 to ease congestion and manage the increasing volume of traffic on the M25.
The scheme will include upgrading the traffic signals throughout the junction, adding an extra lane on the A217 northbound approach, widening into the existing verge and extending the anti-clockwise exit slip road.
Works will also add an extra lane on the north circulatory section of the roundabout, widen lanes on the east and west bridge section of the roundabout as well as widen and realign the A217 southbound to two lanes that merge prior to Wray Lane.
The junction is at Reigate Hill, at the intersection of the M25 with the A217. It serves routes towards both London and the south-coast. The signal-controlled junction is now operating above its design capacity which leads to traffic queues during peak hours, especially on the A217 and M25 eastbound off-slip.
The improvements will reduce congestion and improve journey time reliability in and around the junction.
