By the early 20th century the bridge was proving inadequate for the increasing traffic, particularly with the introduction of motorised transport, and a speed limit was enforced. With the remaining investment income from tolls insufficient to pay for major reconstruction, on 31 March 1931 the bridge was taken into the joint public ownership of Surrey and Middlesex councils, and proposals were made to widen it. The plans were strongly opposed on aesthetic grounds, and the decision was taken to build instead a new bridge a short distance downstream to relieve traffic pressure.
