A354 road

The A354 is a primary route in England which runs from Salisbury in Wiltshire to Easton on the Isle of Portland in Dorset, a total distance of 51 miles . From Salisbury the road crosses Cranborne Chase. At Woodyates the road follows the route of Ackling Dyke, a Roman Road for a short distance. The A354 briefly merges with the A350 at the Blandford Forum bypass before crossing the Dorset Downs and merging with the A35 at the Puddletown bypass. 7 miles to the west it splits from the Dorchester bypass and runs south. The road now bypasses Upwey and Broadwey on a new section of road which has some two lane sections going north and one lane continuously going south towards Weymouth. After the old and new sections meet at Manor Roundabout the road follows down Weymouth Way alongside Radipole Lake. The final stretch runs across a short bridge over Chesil beach onto Portland.
