A350 road
The A350 is a north-south primary route in southern England, that runs from the M4 motorway in Wiltshire to Poole in Dorset.
Route
Starting at junction 17 of the M4 motorway north of Chippenham, the first three miles are a dual carriageway to the northern outskirts of Chippenham, where a partly light-controlled roundabout splits traffic between the bypass section and the road into the town centre. The Chippenham bypass is punctuated by six more roundabouts, the last being at the Lackham College. In so doing it crosses the A420 to Bristol and the A4 for Bath to the West and Calne to the East.
It then goes past the small village of Lacock before reaching Melksham four miles later. The road then follows the Semington bypass, opened in 2004, to Westbury, crossing the A361 between Trowbridge and Devizes. This section of the road has two light-controlled junctions to connect the road to outlying areas of Trowbridge before reaching the Yarnbrook roundabout. This section is approximately 5 miles long.
