The Royal Albert Bridge is a railway bridge which spans the River Tamar between Plymouth, Devon and Saltash, Cornwall. Its unique design consists of two 455 feet lenticular iron trusses 100 feet above the water, with conventional plate-girder approach spans. This gives it a total length of 2,187.5 feet. It carries the Cornish Main Line railway in and out of Cornwall. It is adjacent to the Tamar Bridge which opened in 1962 to carry the A38 road.
The Royal Albert Bridge was designed by Isambard Kingdom Brunel. Construction commenced in 1854 and the completed bridge was opened by Prince Albert on 2 May 1859. It has attracted sightseers since its construction and has appeared in many paintings, photographs, guidebooks, postage stamps and on the UK £2 coin. Anniversary celebrations took place in 1959 and 2009.

The Tamar Bridge is a road bridge at Saltash and Plymouth in southwest England carrying traffic between Cornwall and Devon over the River Tamar. It is adjacent to the Royal Albert Bridge.
When it opened in 1961, the Tamar Bridge was the longest suspension bridge in the United Kingdom. In 2001 it became the world's first suspension bridge to be widened (from three to five lanes) using cantilevers.
Construction of the Tamar Bridge began in July 1959. Before the Tamar Bridge was opened, most travellers between Saltash (on the Cornish side) and the Devon city of Plymouth used ferries. The Tamar Bridge carries approximately 40,000 vehicles every day. It is co-owned by Plymouth City Council and Cornwall Council. A toll of £1.50 per car is charged when driving from Cornwall into Devon if paid in cash. Motorcycles do not have to pay.

Isambard Kingdom Brunel FRS (9 April 1806 – 15 September 1859), was a mechanical and civil engineer who is considered "one of the most ingenious and prolific figures in engineering history", "one of the 19th century engineering giants", and "one of the greatest figures of the Industrial Revolution, He changed the face of the English landscape with his groundbreaking designs and ingenious constructions". Brunel built dockyards, the Great Western Railway, a series of steamships including the first propeller-driven transatlantic steamship, and numerous important bridges and tunnels. His designs revolutionised public transport and modern engineering.
During his career, Brunel achieved many engineering firsts, including assisting in the building of the first tunnel under a navigable river and development of SS Great Britain, the first propeller-driven, ocean-going, iron ship, which, when built in 1843, was the largest ship ever built.
Brunel astonished Britain by proposing to extend the Great Western Railway westward to North America by building steam-powered, iron-hulled ships. He designed and built three ships that revolutionised naval engineering: the SS Great Western (1838), the SS Great Britain (1843), and the SS Great Eastern (1859).

The Tamar (Cornish: Dowr Tamar) is in south west England, it forms most of the border between Devon and Cornwall.
The Tamar's source is 3 miles from the north Cornish coast, but it flows southward and its course runs across the peninsula to the south coast. The total length of the river is 61 miles. At its mouth, the Tamar flows into the Hamoaze before entering Plymouth Sound. Tributaries of the river include the rivers Inny, Ottery, Kensey and Lynher (or St Germans River) on the Cornish side, and the Deer and Tavy on the Devon side.
