The Tamar Bridge is a major road bridge over the River Tamar between Saltash, Cornwall and Plymouth, Devon in southwest England. It is 335m long, running adjacent to the Royal Albert Bridge, and part of the A38, a main road between the two counties.
During the 20th century, there was increasing demand to replace or supplement the Saltash and Torpoint ferries, which could not cope with the rise in motor traffic. After the Government refused to prioritise the project in the 1950s, it was self-financed by Plymouth City Council and Cornwall County Council. Construction was undertaken by the Cleveland Bridge & Engineering Company and began in 1959. It was unofficially opened in October 1961, with a formal presentation by Queen Elizabeth The Queen Mother in April 1962. A reconstruction of the bridge began in 1999 after it was found to be unable to support a European Union requirement for goods vehicle weights. The work involved building two new parallel decks while the original construction was completely rebuilt. The project was completed in late 2001 and formally opened by Princess Anne in April 2002. The extra decks have remained in use, increasing the bridge's capacity.
The bridge is tolled for eastbound travel, with a discount available via an electronic payment scheme. It has become a significant landmark in Plymouth, Saltash and the surrounding area, and used on several occasions for protests or to highlight the work of charities and fundraisers.
