Drivers heading in and out of Bristol were caught up in long tailbacks on the M4 motorway after a multiple crash this morning.

Three lorries - including one carrying concrete blocks - collided at about 6am at junction 18 of the motorway, which is the junction for the A46 for Chipping Sodbury and Bath.

Both directions of the motorway were closed.

Officers said the lorry carrying the concrete blocks ended up on its side lying across the motorway, scattering its load across all lanes.

Traffic travelling both directions along the motorway were diverted off the motorway via the slip roads at junction 18 to allow the police and highways agency to clear the motorway of the concrete blocks.

However, because the peak period of people travelling to work is approaching police are advising people to avoid the area and find an alternative route into work.

The westbound section of the motorway is particularly busy.

Recovery vehicles have been called to the scene.
