Construction of the Transporter Bridge
The construction of the Transporter Bridge, located in Middlesbrough, England, started on the 22nd of July 1910. The bridge was designed by the Cleveland Bridge and Engineering Company in collaboration with the Sir William Arrol & Co., which was responsible for building the steelwork. The construction took three years to complete, with official opening taking place on the 17th of October 1911.
- The bridge had two towers, each 225 feet in height.
- The main span was 580 feet long, and the total length of the bridge was 851 feet.
- The gondola was 160 feet long and 60 feet wide, weighing a total of 198 tons.
The construction of the bridge was a significant feat, mainly due to the challenging nature of the terrain. The area was marshy, and the foundation required special treatment, which was achieved by the use of 2,000 concrete piles driven into the ground. The bridge’s design was based on the French Transporter Bridge in Rouen, but with significant modifications to adapt it to the Middlesbrough terrain.
One of the most challenging aspects of the construction involved the assembly of the steelwork, which was done by a specially designed floating crane, known as the ‘Titan.’ The Titan was the most substantial floating crane at the time, capable of lifting 200 tons, and was used to lift the steelwork into position onto the towers.
