Police closed the M4 between two junctions following a serious crash involving an overturned lorry in the westbound direction. Officers alerted of the crash at around 5am on Thursday morning.
They said junction 37 (Pyle) and junction 38 (Margam) will be closed in both directions for some time to allow emergency services access to the road.
It appears to be an Amazon prime branded vehicle which has been involved in the crash.
Chaos continues in the area, with congestion felt to junction 36 (Bridgend[1] / Sarn service area) and routes through Pyle as traffic diverts.
