UPDATED 8.41am: The queuing eastbound traffic currently stretches from before junction 29 (A48M) to east of junction 23 (M48, Chepstow).

UPDATED 8.08am: The inside lane of the exit slip road at junction 24 (Coldra) remains closed while mergency services deal with the crash there.

Traffic remains very heavy on the M4 eastbound, from shortly before junction 29 (A48M), to east of junction 23 (M48, Chepstow) due to the two incidents this morning.

UPDATED 7.33am: There is a queue of more than half a mile too, on the M48 west, at the junction with the M4, due to Chepstow area traffic needing to join the M4 at junction 23a if they wish to go east.

This is due to the Severn Bridge being closed due to high winds, and is adding to the congestion due to the crash.

UPDATED 7.29am: There is a two-mile tailback eastbound on the A4810 towards junction 23a of the M4 (Magor services).
