Waterloo Bridge. Showing above the bridge (left to right) are St Pauls Cathedral, Tower 42 and the Swiss Re building (the "Gherkin")
The first bridge on the site was designed by John Rennie and opened in 1817 as a toll bridge. Before its opening it was known as 'Strand Bridge'. It was nationalised in 1878 and given to the Metropolitan Board of Works, who removed the toll from it. Serious problems were found in its construction and the new owners reinforced it.
By the 1920s the problems had increased. London County Council decided to demolish it and replace it with a new structure designed by Sir Giles Gilbert Scott. The new span was partially opened in 1942 and completed in 1945. It was the only Thames bridge to have been damaged by German bombers during World War II.
