The A345 between Blandford Forum and Dorchester is closed due to a collapsed manhole cover. 

The road is closed between Tesco Roundabout and Thornicombe.

Temporary lights are being set up around the manhole cover to reopen the road as soon as possible. 

There are currently severe traffic delays between Blandford St Mary and Littleton Drove, Thornicombe. 

It is expected the road will be open by midday.
