From Kingsbridge, the A379 passes through the villages of Aveton Gifford, where it crosses the River Avon, and Modbury, shortly after which it crosses the River Erme. The villages of Yealmpton, on the River Yealm, and Brixton follow. The road then runs into the suburbs of Plymouth, bypassing Plymstock before crossing the estuary of the River Plym on the Laira Bridge. The A379 ends on the west side of the Plym, joining the A374 just over east of Plymouth city centre.
