There's queueing traffic and the exit slip road is closed due to an overturned lorry on the M5 Distributer Northbound between J16 A38 (Aztec West) and J15 M4 (Almondsbury Interchange). Congestion on the M5 is back to J18a M49.
The distributor road runs parallel to the main carriageway acting as a filter to join the M4 East. Traffic can still join the M4 West. The main carriageway of the M5 remains open.
Diversion - For traffic heading to M4 East: come off the M5 North at Junction 18 and use the M49. Any traffic further up will continue up to M5 J14 to turn round to head M5 South.
