A main Weymouth to Bridport route has been shut.

Police have closed a section of the Coast Road from Freshwater Holiday Park to the Crown Roundabout.

The cause of the sudden closure is believed to be a crash.

One motorist described seeing police and ambulance in attendance of an incident.

The road has since re-opened.

According to traffic monitoring site Inrix, there was queuing traffic at the Crown Roundabout and others described 'grid lock' traffic on alternate routes  including Shipton Lane.

More to follow.
