The Clifton Suspension Bridge
Bristol, England

The bridge was built in 1864 by Isambard Kingdom Brunel. the bridge is located in Bristol, England over the Avon Gorge. It is named the Clifton Suspension Bridge. It was named the Clifton Suspension Bridge because the area it was built is or was called Clifton. In 1822 there were bridge plans proposed for Clifton and then again six years later.
In 1828, the Bristol Chamber of Commerce was putting pressure on the Society of Merchant Venturers to build a bridge and have a steamship service to Ireland. This was seen by Bristol as an economical venture for the city to make money and benefit from becoming a profitable trade location.
In 1829, the Society of Merchant Venturers set up a committee of commissioners. They prepared an Act of Parliament to change William Vick’s Will which stipulated a toll free stone bridge. William Vick was a wealthy wine merchant originally from Minchinhampton, England. In his will he left £1000 to the Society of Merchant Venturers. He wanted them to invest the money until it reached £10,000, at that time he requested they build a toll free stone bridge across the Avon Gorge from Clifton to Leigh Down. Vick believed that it would be a great public utility for the area.
in 1829, the amount of money had grown to £8000. October 1, 1829 the Commissioners announced a competition for an iron suspension bridge at Clifton Down. They gave competitors just seven weeks to put in their entries. they were to build the highest and longest suspension bridge in the world. According to the visitor’s center at the bridge, there was no list found recorded of the entries but there have been various sources claiming 22 entries were submitted.
Many people submitted designs, ranging from all stone bridges that estimated up to £93,000 to fancy bridges that seemed to be time consuming to build and not very practical.
An amazing four entries were submitted by a young man named Isambard Kingdom Brunel. He was 23 years old and did not have much experience with suspension bridges only the two short span bridges that he worked with his father on in Reunion Island in the Indian Ocean.
Many of the designs were rejected due to cost and appearance. Five designs were left to choose from. They decided to ask Thomas Telford the Father of Civil Engineering, as well as, the first President of the Institution of Civil Engineers. In his experience, he was cautious about designs larger than 600 feet/184 meters due to his bridge in Menai being damaged from storms. He dismissed Brunels designs stating that ‘although they were pretty and ingenious, they would certainly tumble down in a high wind.’
Mr. Telford decided that none of the designs were suitable for adoption. There were two designs that he felt were practical so he recommended that they should share the prize money but that they would not be appointed because the amount of alterations would make the schemes a new design. This would save the committee any embarrassment.
So, they were left with the option to invite Mr. Telford to produce a suitable design. He was able to design it in three weeks time. It was a short span suspension bridge with two masonry towers with a span of 110 meters/360 feet.
In October of 1830 the committee held a new competition as there were many arguments about the design and the financing of the bridge. Local citizens were complaining that there was no budget in place, as well as the practicality of the designs to make the gorge still have a nice appearance. In October of 1830 the competition was given a deadline of December 18th. In this competition Thomas Telford entered as an equal competitor with everyone else. For this competition, there were thirteen recorded entries. The judges for the competition were more from a scientific and mathematical background.
In this competition the winners were: 1st Smith and Hawkes, 2nd Isambard Brunel, 3rd Capt. S Brown, and 4th James M.Rendel. There was debate between Brunel and Davies Gilbert in regard to his design. Gilbert required Brunel to make several changes to his design which made his bridge limited to 214 meters/ 703 feet. Two days later Brunels design was declared the winner.
To find out more about how the bridge was built and what went on during the building process, I suggest you go visit Bristol and see this beautiful bridge. The finished product was completed on 8 December 1864. The bridge is 414 meters/1352 feet long and 9.5 meters/31 feet wide. It is also 75 meters/245 feet above the high water level.
What I thought was cool about the bridge was the view from the sides, you could see almost all of Bristol. Also the Gorge was very cool, it had cool looking mountains on both sides and a muddy river. We took many pictures of it and I will try to share them with you.
