Progress report

Detailed design for the work at this junction has been completed. In agreement with our partners at Surrey County Council, the start of improvement work at junction 8 of the M25 at Reigate will take place April 2021. This is to minimise disruption and better coordinate with our nearby work to upgrade the M23 to a smart motorway.

See the 'General information' document in the section below for answers to some frequently asked questions.

What's next?

Work will start April 2021.

Works will include:

  • upgrading the traffic signal installation 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
  • adding an extra lane on the north circulatory section of the roundabout
  • widening lanes on the east and west bridge section of the roundabout
  • improving road signs and markings
  • widening and realignment on the A217 southbound to two lanes that merge prior to Wray Lane

Why we need this scheme

Junction improvement to ease congestion and manage the increasing volume of traffic on the M25.

The M25 junction 8 was opened for traffic in 1986. The junction sits atop Reigate Hill at the intersection of the M25 with the A217 and serves destinations 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.

Aims

  • upgrading the traffic signal installation 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
  • adding an extra lane on the north circulatory section of the roundabout
  • widening lanes on the east and west bridge section of the roundabout
  • improving road signs and markings
  • widening and realignment on the A217 southbound to two lanes that merge prior to Wray Lane
