The Haengju Bridge (Korean: 행주대교) crosses the Han River in South Korea and connects the city of Goyang and the Gangseo District, Seoul.

[1] The bridge was first completed in 1978,[2] but the bridge was very narrow and could not handle the increased traffic as the neighboring cities of Ilsan and Bucheon experienced housing booms.

Repairs took three more years, and the bridge opened in 1995.

[3] Construction on a third bridge began in the space between the first and the second in 1996 and finished in December 2000.

Currently, the second bridge handles southward traffic and the third bridge handles northward traffic.
