It's often difficult for people caught up in traffic jams on the motorway to understand why the road has to be closed for what appears to be a long time.
We work hard to minimise disruption on the road network but as the timeline below shows, it's important for us and the family of the injured person(s) to understand exactly what happened.
At around 4am on 29th October 2013, two articulated lorries and a van collided between junctions 13 and 14 of the M5 near to Michaelwood services in South Gloucestershire. Sadly, one man had died in the collision. The southbound carriageway of the motorway was closed until approximately 11.30am when one of the lanes was re-opened.
