The A35 between the Football Ground Roundabout at Dorchester and the Monkeys Jump Roundabout at Poundbury was closed in both directions.
This was due to a trailer full of hay overturning on a verge between the two roundabouts.
Police received a call at 9.12am today to reports of the incident.
The road has been re-opened following recovery and clean-up work.
