THE A350 BEGINS its route at the M4’s junction 17, heading south before it turns right onto the Chippenham Bypass.
The road bypasses the time-warp picturesque village of Lacock, and continues on to the small market town of Melksham, avoiding the town centre. It then bypasses Trowbridge to the east, passing West Ashton and turning at Yarnbrook to head through the market town of Westbury, on the edge of Salisbury Plain.
