A serious multi-car crash that closed the M23 between Gatwick Airport and the M25 has caused gridlock across the east of the county.

The crash has left one person with potentially serious injuries and led to a large diesel spillage.

One lane of the motorway is now open to allow trapped traffic to pass but the motorway remains closed northbound due to the need to repair the road surface.

Police are advising motorists to avoid the M23 and this has caused traffic to build up on alternative routes.

Google Maps' traffic watch has a live traffic scale, from green to dark red, with green suggesting fast traffic, and dark red meaning it's very slow.

There is congestion on a number of routes around the M23


There is severe congestion southbound on the A22 from the M25/B2235 roundabout. Google maps' traffic watch shows the road as dark red, meaning traffic is at its most severe.

Traffic eases off just north of South Godstone, but expect severe delays for much of the afternoon as the M23 incident is dealt with.

The A217 is very slow southbound from Reigate all the way to Horley. Google maps' traffic watch is once again showing dark red lines all along the route, so stay away if possible.


The traffic on the A23 is less severe, but still worth avoiding if you can. From the London Road/A2011 roundabout westbound all the way to Southgate there is intermittent bad traffic, particularly around the Crawley Avenue Roundabout.

The A25 eastbound between Godstone and Bletchingley is severely congested, with a dark red line all along that route, which is 1.7 miles long.

The A25 is mostly clear around Reigate, but has a number of spots of severe traffic to avoid. The A25/Reigate High Street Junction is showing severe delays and very slow moving traffic.
