The Tamar Bridge on the A38 forms the major of two crossings of the River Tamar between Plymouth and Cornwall (the other being the Torpoint Ferry on the A374). The suspension bridge was built to carry a three-lane tidal flow road (reversible middle lane) and opened in 1961 with toll booths located on the Plymouth side. In 1999-2001 it was widened by the addition of two cantilevered lanes, one on each side of the existing deck – the first suspension bridge in the world to be widened by such a method.
The present five lanes (counting from north to south) carry:
eastbound local traffic from Saltash
eastbound through traffic from Cornwall
east or westbound through traffic (tidal flow)
westbound traffic to Saltash and Cornwall
a footpath and cycleway.
Tolls are collected for all vehicles when travelling Cornwall to Devon only; pedestrians and cyclists are free.
