Junction Type
3-level stacked roundabout
Roads Joined
M25, A3

The Wisley Interchange is junction 10 of the M25, with the A3. It is a 3-level stack roundabout, with added left turn lanes.

This junction can sometimes be a bit of a pain. Were it not for the A245 junction the A3 has just up the road, (which hinders how far the sliproads can go) you wonder why they didn't spruce it up like the M25's better (and emptier) junction with the M23. The other problem is that the A3 drops from 3 Lanes to 2 over the M25, losing and then regaining a lane each way, which can be exceedingly annoying during the rush hour.

Another strange idea is that the A3 Southbound access slip takes ages to join the A3 carriageway. Instead, we have a mini exit for Effingham. All a bit weird...

2016 Upgrade Plan

In 2016, Highways England announced a plan for a comprehensive upgrade to the Wisley Interchange. A Public Consulation was announced in December 2016, containing two possible options:

  • Option 9 - Two Semi-direct connectors from the A3 to the M25, and additional free-flow left turns
  • Option 14 - Enlargement of the existing 3-level-stack roundabout to accommodate more traffic using extra lanes. Free flow left turns are also provided.

An addition option was rejected before consultation, but was still shown in the document:

  • Option 16 - Cyclic interchange providing free-flow movements in every direction
