The Highways Agency website shows Southbound traffic on M5 is bumper-to-bumper as far north as 11A for Gloucester right down to coach fire site near Bristol.
They expect the road to start clearing from 12.30pm, but there are likely to be considerable delays for holidaymakers getting away for the Bank Holiday weekend. The A38 is also reported to be very busy in the area.
No Worcester Warriors players or staff are reported to be injured after their coach caught fire. Their match is rescheduled at Ospreys for 4.30pm.
