Namhangdaegyo (남항대교) is a girder bridge in Busan.

It spans Yeongdo-gu and Seo-gu and is 1.8 km long in total with four lanes of traffic (two in each direction).

The bridge was constructed as part of the Southern Busan Thoroughfare (부산남부순환로) initiative.

It has significantly reduced time between Yeongdo Island and western Busan.

Initially, a trip from Seo-gu to Yeongdo-gu (or vice versa) was 7 km long and would take 30 minutes.
