Yanghwa Bridge

Tangshan Railway Bridge

The Yanghwa Bridge (양화대교) carries National Route 6 over the Han River between the Mapo-gu District and Yeongdeungpo-gu District in Seoul, South Korea.

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.
