Live updates as M4 crash closes lane near Cardiff causing long delays

A lane of the M4 is closed following a crash where a van has gone off the road. Police are at the scene on the motorway westbound between J33 Capel Llanilltern and J34 Miskin.

J33 is the exit for Cardiff via Culverhouse Cross, and traffic has begun to build up on the A4232 towards the on-slip. The crash has caused queueing traffic in the area, with Traffic Wales warning of "heavy congestion" westbound.

The incident was first reported at 12.23pm. A statement by Traffic Wales reads: "M4 Westbound J33 Capel Llanilltern - J34 Miskin. Lane 1 closed. Heavy congestion in the area."

Many people will be travelling to Cardiff to watch the Six Nations game on Saturday afternoon, although the game itself is in England. Roadworks originally planned for J26 from Saturday morning, which Traffic Wales said would cause delays, have since been postponed until Sunday.
