About Sangyo Bridge
Twin beam bridges, each carrying two lanes of traffic, were opened on November 28, 1967, to serve an upcoming industrial area for Pohang. A four-lane tied arch bridge was constructed from 1977-78 1 2 and a companion six-lane deck beam bridge was completed in 1995. 2
The 1977-78 and 1995 structures received pier reinforcement and pavement rehabilitation in late 2015 at the cost of 1.7 billion ₩. 1 2
A cycle-track and pedestrian bridge were later constructed adjacent to the 1995 structure.
