Namhang Bridge, Road bridge in South Korea.

Namhang Bridge (Namhangdaegyo) is a sea crossing of 1,941 m and 18.5–38.6 m in width, with two lanes in each direction, linking Amnam-dong in Seo-gu to Yeongseon-dong in Yeongdo-gu, Busan. It forms part of Busan Metropolitan Route 66. A 3 m wide walkway runs along the inner-harbour side, and the bridge carries landscape lighting on the theme "a gateway to the new century".

Construction began in October 1997 but was suspended from November 1999 to May 2002; the bridge finally opened on 9 July 2008 after about ten years and 355 billion won. It replaced the ageing Yeongdo Bridge as a crossing and cut the Seo-gu–Yeongdo trip from 7 km and 30 minutes to 2 km and 3 minutes.

The name Namhangdaegyo means "Great Bridge of the South Port", from nam (south), hang (harbour) and daegyo (large bridge). The bridge crosses the South Port between Yeongdo-gu and Seo-gu. Its deck lighting, themed "a gateway opening a new century", illuminates the night sea of the South Port.

Namhang Bridge is a motor-vehicle road, but a 3 m wide promenade on the inner-harbour side lets pedestrians and cyclists cross in both directions. Motorcycles other than emergency vehicles such as police and fire units are not allowed. The bridge carries Busan Metropolitan Route 66, and a future Cheonma Tunnel link is planned to connect it with Eulsukdo Bridge.

The bridge carries Busan Metropolitan Route 66 and is planned to link to Cheonma Tunnel, which would connect it with Eulsukdo Bridge; the crossing would then be widened from four to six lanes. Its 3 m promenade along the inner harbour lets pedestrians and cyclists cross, while motorcycles other than emergency vehicles are barred.
