context_page_description: Chiswick Bridge is a reinforced concrete deck arch bridge over the River Thames in west London. One of three bridges opened in 1933 as part of an ambitious scheme to relieve traffic congestion west of London, it carries the A316 road between Chiswick on the north bank of the Thames and Mortlake on the south bank.
  Built on the site of a former ferry, the bridge is 606 feet long and faced with 3,400 tons of Portland stone. At the time of its opening its 150-foot central span was the longest concrete span over the Thames. The bridge is possibly best known today for its proximity to the end of The Championship Course, the stretch of the Thames used for the Boat Race and other rowing races.
context_section_description: The new bridge was designed in reinforced concrete by architect Sir Herbert Baker and engineer Alfred Dryland, with additional input from Considère Constructions, at the time Britain's leading specialist in reinforced concrete construction.
  The bridge has concrete foundations supporting a five-arch cellular reinforced concrete superstructure. The deck is supported by a concealed lattice of columns and beams rising from the arched superstructure. The structure is faced with 3,400 tons of Portland stone, except for underneath the arches. The bridge is 606 feet (185 m) long, and carries two 15-foot (4.6 m) wide walkways, and a 40-foot (12 m) wide road. At the time it was built, the 150-foot (46 m) central span was the longest concrete span over the Thames.
  Unusually for a Thames bridge, only three of Chiswick Bridge's five spans cross the river; the shorter spans at each end of the bridge cross the former towpaths. To allow sufficient clearance for shipping without steep inclines, the approach roads to the bridge are elevated from some distance back from the river.
  The bridge was built by the Cleveland Bridge & Engineering Company at a cost of £208,284 (about £14,896,000 in 2020). Additional costs such as building the approach roads and purchasing land brought the total cost of the bridge to £227,600 (about £16,277,000 in 2020). The Ministry of Transport paid 75% of the cost, with Surrey and Middlesex county councils paying the remainder.
  The bridge was generally well received. Country Life praised the design as "reflecting in its general design the eighteenth century Palladian tradition of Lord Burlington's famous villa at Chiswick".
