Constructed by engineer James Meadows Rendel. He'd already had success with a chain ferry crossing the river Dart and used the same method to bridge the Tamar. Rendel laid iron chains on the Tamar riverbed - steam powered boats used these to pull themselves across.
The chains then sank to the bottom to allow other ships and boats up and down the river. Engineers vertically sank a This rested on the bedrock with the top just above water level. Workers used the cylinder to build a This column formed the bridge's mid-stream support pier. The wrought iron spans for the bridge were built on shore, then floated out into the river for assembly.
Was then the longest suspension bridge built in the UK. Engineers constructed 2 concrete towers to support the bridge, each 67m high. Support cables were hoisted over these. They then attached hangers — steel suspender cables — to the support cables.
Directors had the words 'IK Brunel, engineer, ' added in large metal letters to either end of the structure. A traditional Cornish tale says that the Devil would never cross the Tamar in case he was turned into a filling in a Cornish pasty. The 'Alliterative Morte Arthure', a poem telling the story of King Arthur and dating from around , has a scene set on the Tamar. Arthur is fatally wounded on the river bank in a swordfight with his arch-enemy Mordred.
The job you end up with in civil engineering is likely to link back to what you studied at school, college or university. Here you can see your options at any age. Tamar crossings Year: , , Connected communities The purpose of the ferry and bridges make it easier for people to connect. Economy boosted Trade, commerce boosted by easier routes to market. Solved the problem How do you cross a wide and important river?
These Joint Authorities formed a special partnership in to lobby national government to fund a fixed crossing of the Tamar, but in the face of government inaction, decided in to go forward with the scheme themselves as a local enterprise financed from tolls. Parliamentary powers were needed for compulsory purchase of land, construction of towers in navigable waters, closure of existing roads and them to subsequently charge tolls.
The Tamar Bridge Act gained Royal Assent on 27th July and provided these powers and the detailed design could then commence. The Act also created the Tamar Bridge and Torpoint Ferry Joint Committee, which was charged with the subsequent operation, maintenance and improvement of both the planned Tamar Bridge and the existing chain ferry operation at Torpoint. Mott Hay and Anderson designed what was to be the first significant post-war suspension bridge, and the longest ever in the UK.
Guidebooks that came out that year were lavish with their praise "For novelty and ingenuity of construction this bridge stands unrivalled in the world.
It was joined in by the Tamar Bridge , built to accommodate the influx of cars, hitherto forced to travel between Devon and Cornwall by means of a small ferry. The Tamar Bridge was the first major suspension bridge to be built after the war, and for a time the longest suspension bridge in England. In the bridge was strengthened and widened two lanes were added for local traffic and pedestrians , and became the first bridge to remain open to traffic while the work was carried out, using an innovative system of cantilevers.
The project won several awards and the attention of international figures such as Bill Moreau , Chief Engineer for the New York State Bridge Authority, who visited Cornwall in order to see if the technique could be adapted for use in the States.
