THREE lanes of the M5 have became blocked this afternoon (Fri) following an accident.

All but one lane of the southbound carriageway between junction 19 for Portishead and junction 20 for Clevedon became blocked due to the sheer volume of traffic backing up near the site of the incident, which involved three cars and happened at 2.15pm.

All three of the affected lanes have been reopened but drivers are warned to still expect delays.
