Any of several successive structures spanning the River Thames.
The Old London Bridge of nursery-rhyme fame was built by Peter of Colechurch between 1176 and 1209, replacing an earlier timber bridge. Because of obstructions encountered in building the cofferdams, the arch spans varied from 15 to 34 ft (4.610.4 m); the uneven construction resulted in frequent need for repair, but the bridge survived more than 600 years. Its roadway was loaded with a jumble of houses and shops, many projecting out over the river. It was demolished and replaced in the 1820s by New London Bridge, designed and built by John Rennie, Sr. (17611821), and his son John Rennie, Jr. (17941874). In the 1960s it was again replaced; the old masonry facing was dismantled and reerected at Lake Havasu City, Ariz., as a tourist attraction.
