Delays after five-vehicle M4 crash at Briton Ferry
Two lanes have re-opened on the M4 after a crash involving five vehicles.
Emergency services were called to the Briton Ferry Bridge between junction 42 for Fabian Way and junction 41 for Baglan at about 07:25 BST.
Police directed traffic on the hard shoulder to pass the crash but some traffic also used the A48 Old Briton Ferry Bridge.
Traffic Wales said the old bridge was heavily congested and the M4 traffic went back to junction 44 (Llansamlet).
