Problems with overhead power cables have forced Highways England to shut the M5 between J22 and J23
The M5 has been closed in both directions between junction 22 Burnham-on-Sea and junction 23 Bridgwater because of problems with overhead power lines.
Motorists are being diverted via the A38, but severe congestion is expected in the area, with many people travelling to the coast or the Glastonbury Festival. Drivers are advised to find another route if possible, and - in the hot weather - to carry plenty of water in case their journey is delayed.
Highways England say they are working with Western Power and will reopen the M5 as soon as it is safely possible.
Further incident information is available from the Highways England website and the regional Twitter feed @HighwaysSWEST
