The bridge connects Mapo District on the north side of the river to Yeongdeungpo District on the south side of the river.

[citation needed] Due to increasing traffic, construction for an expansion started in 1979[citation needed] and the new eight lane bridge was completed in February 1982.

[1] The old bridge's upper structure has a width of 18 m (59 ft), length 1,053 m (3,455 ft), and is composed of steel plate girders and concrete box girders.

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.
