Drivers leaving the South West have been caught in more than three hours of queues caused by emergency repairs to a bridge.
Three lanes of the M5 northbound are closed after a faulty bridge join was discovered on the Avonmouth Bridge, near junction 18, at about 07:00 BST.
Queues are currently stretching 14 miles (22km) back to junction 21 for Weston-super-Mare.
A National Highways spokesperson has said the lanes are expected to remain closed for several hours.
