M4 crash causes long queues - live updates

There are long delays on the M4 between Cardiff and Newport after a crash. Two lanes of the eastbound carriageway are closed due to an accident between J29 A48(M) to J28 A48 (Tredegar Park).

Traffic cameras show heavy congestion in the area with miles of gridlocked queues. All three lanes of the carriageway are bumper to bumper while the incident is ongoing.

The queues are trailing back to the east of Cardiff and the A48 also appears to be affected as traffic backs up.
