In 1963 it was proposed to replace the bridge with a modern development containing seven floors of shops, office space, hotel rooms and leisure facilities supported above the river, but the plans were abandoned because of costs. With the exception of alterations to the road layout and the balustrade, the design and appearance of the current bridge has remained almost unchanged since 1907. The bridge today is an important part of London's road system and carries the A202 road and Cycle Superhighway 5 (CS5) across the Thames.
