A three-span reinforced concrete road bridge faced in Portland stone. Together with Twickenham Bridge, it was built as part of the Chertsey arterial road scheme (A316), designed to relieve traffic pressure on Hammersmith Bridge and in Richmond.
The Chertsey scheme was the subject of a special conference convened in January 1925 by the Ministry of Transport together with the Middlesex and Surrey local authorities.
In 1928, Parliament passed the Act that enabled the construction of Chiswick Bridge to begin. It was opened by the Prince of Wales on the 3rd of July five years later, along with Twickenham Bridge and Hampton Court Bridge — a busy day for the prince.
The bridge's central span measures 45.7m and the other two 38m each. Secondary stresses were avoided by inserting hydraulic jacks in the tops of the arches, which have a bush hammered finish on their exposed surfaces. The Portland stone used for facing the bridge is also used for the balustrade.
The roadway is 12.2m wide, flanked by 4.6m footways. The contract for the bridge included its approaches and roadworks.
Chiswick Bridge's engineer was Alfred Dryland, who held the post of Middlesex County Engineer at the time. However, the designer of the bridge, Sir Herbert Baker, was an architect of some distinction and some have identified Chiswick Bridge as marking a change in the relationship between engineer and architect in bridge design. In the century prior to this, engineers had generally taken the lead.
