Cornwall borders the county of Devon at the River Tamar. Major roads between Cornwall and the rest of Great Britain are the A38 which crosses the Tamar at Plymouth via the Tamar Bridge and the town of Saltash, the A39 road (Atlantic Highway) from Barnstaple, passing through North Cornwall to end in Falmouth, and the A30 which crosses the border south of Launceston, crosses Bodmin Moor and connects Bodmin and Truro. Torpoint Ferry links Plymouth with Torpoint on the opposite side of the Hamoaze. A rail bridge, the Royal Albert Bridge built by Isambard Kingdom Brunel (1859), provides the only other land transport link. The city of Plymouth, a large urban centre in south west Devon, is an important location for services such as hospitals, department stores, road and rail transport, and cultural venues, particularly for people living in east Cornwall.
