It starts on the A362 Warminster Road in Frome. It heads east, climbing up Styles Hill and crossing the A361 without a junction (access is via the A362). It then crosses from Somerset into Wiltshire and passes through Chapmanslade before reaching the A36 at Black Dog Hill. The junction is grade-separated, despite the fact the A36 is only S2, with that road using a new cutting down the hill. The northbound slip roads use the old line of the A36 south from here whilst the southbound slip roads are of newer construction on the far side of the bridge.
Continuing east, we cross Chalcot Park and go under the Bath to Salisbury railway line before meeting the B3099 at the eastern end of Dilton Marsh. We then navigate our way through the new housing estates that surround Westbury. The new roads in this area are being built with the long-proposed Westbury bypass in mind, but whether they will ever be linked up is quite another matter. Several roundabouts later, the road ends at a T-junction on the A350.
