The section of the A38 between the A382 junction and Ashburton was built on a new alignment parallel to the old road, and was opened in 1974. Trago Mills, a locally well known retailer, is passed by the road. The Ashburton bypass, much like the Kennford bypass, uses the alignment of a much older 1930s single carriageway bypass, which was subsequently upgraded to dual carriageway by 1974. At the town of Buckfastleigh, the route once again bypasses on a new alignment, although due to the challenging topography of the area, the road crosses part of the town on a viaduct. The road occupies part of the alignment of the former Totnes to Ashburton railway line. From Buckfastleigh to the A385 junction, the current road follows the route of original single carriageway, with the majority of this section being upgraded between 1973 and 1974, although a small section at Dean Prior was upgraded between 1966 and 1967. This section is of a poor quality when compared to the majority of the route between Exeter and Plymouth, containing several side turnings with short exit/entry slips, and properties which back onto the road.
