The Yanghwa Bridge (양화대교) is located in Seoul, South Korea and carries NR 6 over the Han River between the Mapo-gu District and Yeongdeungpo-gu District.
The first crossing at that location was the Second Han River Bridge that was constructed from June 1962 to January 25, 1965 by Hyundai Engineering and Construction at a cost of 512,420,000 won.(2) It was a major thoroughfare from Seoul to the western coast. But as Seoul began to rise in population, and the western coast became increasingly urban, construction began on a second span in January 1979 which was completed on February 2, 1982 at a cost of 14.9 billion won.
The Yanghwa Bridge was reinforced and repaired in 1996 and reopened on April 1, 2002 at a cost of 101.8 billion won.(2)
Construction began in February 2010 on a project to rebuild the center main span of the Yanghwa Bridge to allow for larger ships to navigate the Han River as part of a canalization project.(1) The construction project involves the construction of a tied arch center span that will allow 5,000 ton-class ships to navigate 112 meters between the piers, up from 25 to 50 meters. The project is expected to cost 582 billion won.
