[1][3] In 1907 the bridge was widened again with a further track, on the western side, for the London, Brighton and South Coast Railway.

[1][4] In 1963–1967, the structure of the bridge was completely renewed and modernized, leaving only the cores of the original piers.

At the same time, a tenth track was added in a space formerly used for gas mains.

To minimize disruption to traffic, each track was renewed separately, and put back into service before the next one was closed.

[5][6] It was said to be the busiest railway bridge in the world with 1000 trains crossing per day in 1968.
