Twickenham Bridge crosses the River Thames in southwest London, England. Built in 1933 as part of the newly constructed "Chertsey Arterial Road", the bridge connects the Old Deer Park district of Richmond (historically Surrey) on the south bank of the river to St. Margarets (historically Middlesex) on the north bank, both within the London Borough of Richmond upon Thames. Twickenham Bridge gets its name from the fact that it is on the road to the town of Twickenham (also in the same London borough), which is approximately 3 km upstream from Twickenham Bridge, past Richmond Bridge.
