The Yanghwa Bridge ({{Korean|hangul=양화대교}}), formerly known as the Second Hangang Bridge ({{Korean|hangul=제2한강교|labels=no|lit=Second Han River Bridge}}), is an eight lane bridge spanning the Han River in Seoul, South Korea. The bridge connects Mapo District on the north side of the river to Yeongdeungpo District on the south side of the river.{{Citation |last=변 |first=근주 |title=양화대교 (楊花大橋) |work=Encyclopedia of Korean Culture |url=https://encykorea.aks.ac.kr/Article/E0035875 |access-date=2024-07-14 |publisher=Academy of Korean Studies |language=ko}} The bridge is buttressed by the eastern end of the island of Seonyudo, home to Seonyudo Park.{{Cn|date=July 2024}}

The bridge is a combination of two bridges: the old bridge, originally called the "Second Han River Bridge", completed in 1965; and the new bridge, completed in 1982. The old bridge was the first bridge built by Korean technology after independence in 1945 and served as the gateway from Seoul to the west coast.{{Cn|date=July 2024}} Due to increasing traffic, construction for an expansion started in 1979{{Cn|date=July 2024}} and the new eight lane bridge was completed in February 1982.

The old bridge's upper structure has a width of {{Convert|18|m|ft|abbr=on}}, length {{Convert|1,053|m|ft|abbr=on}}, and is composed of steel plate girders and concrete box girders. The new bridge has a width of {{Convert|16.2|m|ft|abbr=on}}, length {{Convert|1,053|m|ft|abbr=on}} and is a steel plate girder bridge. The lower structure has an open caisson well foundation.

The bridge went through repairs and renovations in 1996 and reopened in April 2002 with additional ramps. As of February 2010, the bridge is once again going through renovations by widening the space between bridge posts to allow 5000t ships to pass.{{in lang|ko}} [http://www.hani.co.kr/arti/society/society_general/425983.html Renovations on Yanghwa Bridge starts], The Hankyoreh 2010-06-16.

Yanghwa Bridge also has a song named after it called "양화대교 Yanghwa Bridge" by R&B/soul singer Zion.T in 2014.
