The A381 road is a non-trunk 'A'-class road in Devon, England which serves as an important link between the towns of Teignmouth, Kingsteignton, Newton Abbot, Totnes and Salcombe and many villages in between, with the busiest section having 6 lanes and carrying an average of over 40,000 vehicles per day. The route overlaps with other A-roads for several sections of its length. It is a faster route from Teignmouth to Salcombe than the A379 which meets it at both ends. It is under the control of Devon County Council as highway authority.

The A379 is a road in the English county of Devon. It links points on the edges of that county's two principal cities, Exeter and Plymouth, by an indirect and largely coastal route. The A38 provides a faster and more direct inland route between Exeter and Plymouth, whilst the A380 provides a similarly faster route between Exeter and the Torbay area. However the A379 serves many small coastal communities and ports along the coast. The indented nature of the South Devon coast means that the road is usually out of sight of the sea, but the many rivers and estuaries are crossed by bridges and, in one case, a cable ferry.
