Royal Albert Bridge Totally Explained

Everything about The Royal Albert Bridge totally explained

The Royal Albert Bridge (sometimes called the Brunel Bridge or Saltash Bridge) spans the River Tamar in the U.K. between Plymouth, on the Devon bank, and Saltash on the Cornish bank. It carries the Cornish Main Line in and out of Cornwall.
A short distance to the north of Brunel's bridge, the Tamar is crossed by the Tamar Bridge carrying the A38, one of the two trunk roads connecting Cornwall to Devon.

Construction

The bridge was designed in 1855 by Isambard Kingdom Brunel for the Cornwall Railway Company after Parliament rejected his original plan for a train ferry across the Hamoaze. The bridge consists of two main spans of 455 feet (139 m), 100 feet (30 m) above mean high spring tide, plus seventeen much shorter approach spans. Opened by Prince Albert on 2 May 1859, it was completed in the year of the great engineer's death.
The structure was the third in a series of three notable wrought iron bridges built in the period, and was influenced by the preceding two, both by Robert Stephenson. The two central sections of the bridge are novel adaptations of the design employed for the High Level Bridge across the River Tyne in Newcastle Upon Tyne. These two spans are lenticular trusses with the top chord of each truss comprising a heavy tubular arch in compression, while the bottom chord comprises a pair of catenary shaped members. Each of the trusses is simply supported and therefore no horizontal thrust is exerted on the piers. Between these two chords are supporting cross bracing members and suspension members which trail beneath the bottom chord to carry the railway deck which is a continuous plate beam.
The method of construction was similar to the Britannia Bridge across the Menai Strait in north Wales, in that the spans were constructed on land, then floated into position and raised. Unlike the Britannia, however, the central piers were built up in height three feet (1 m) at a time, and the spans raised that distance, until the design height was achieved. (For the Britannia, the piers were built to full height, and then the span hoisted to design height.) The difficulty of its construction rates it as one of Brunel's great railway achievements.

Inscription

The words I.K. BRUNEL, ENGINEER, 1859 appear in large type on either end of the bridge, added as a tribute after his death. In 1921, new access platforms were added that obscured the lettering. In 2006, Network Rail relocated the platforms, allowing the name to be seen again.

Mentions in popular culture

John Betjeman wrote in the Sunday Times "The Book of the Great Western" (1970): ť :The general grey slate and back gardens of Plymouth, as seen from the Great Western made the surprise of Saltash Bridge all the more exciting. Up and down stream, grey battleships were moored in the Tamar and its reaches. Hundreds of feet below, the pathetic steam ferry to Saltash from the Devon bank tried to compete with Brunel's mighty bridge.

The Royal Albert Bridge is crossed and marveled at by major characters in the alternate history novel, Stars & Stripes Forever, by Harry Harrison. It is referred to as "The Amazing Bridge Across the Tamar River " and is pictured in an accurate woodcut-style drawing by Angela Tomlinson. Details of its design and construction are briefly discussed.
The bridge is depicted in several paintings by mariner and painter Alfred Wallis.
It is mentioned in the Show of Hands song "Cousin Jack".
