Waterloo bridge

First bridge
The first bridge on the site was designed in 1809–10 by John Rennie for the Strand Bridge Company and opened in 1817 as a toll bridge. The granite bridge[2] had nine arches, each of 120 feet (36.6 m) span, separated by double Doric stone columns, and was 2,456 feet (748.6 m) long, including approaches–1,240 feet (378.0 m) between abutments–and 42 feet (12.8 m) wide between the parapets. Before its opening it was known as the Strand Bridge.
During the 1840s the bridge gained a reputation as a popular place for suicide attempts.

Second bridge
In the 1930s London County Council decided to demolish the bridge and replace it with a new structure designed by Sir Giles Gilbert Scott. The engineers were Ernest Buckton and John Cuerel of Rendel Palmer & Tritton. The project was placed on hold due to the Second World War.
Construction of the new Waterloo bridge began in 1942, designed by G. Scott, and lasted only three years, despite the difficulties. There were not enough men, and all the burdens of construction fell on women's shoulders, for which Waterloo is often called the ladies ' bridge. Perhaps partly due to the female energy this time the bridge came out not only beautiful, but also functional. It became another magnificent bridge of London, created for the rapid crossing of the Thames
