Mawon 2nd Bridge post-tensioned using Technology
South Korea's Jungbu Inland Expressway connecting Yeoju in Kyoungkido and Kumi in Kyoungsakbukdo will be completed in 2004. The 151.9 km long four-lane expressway is expected to contribute to the growth of the inland provinces, minimize traffic congestion and reduce travel time. Mawon 2 nd ILM (Incremental Launching Method) Bridge is an important element in the Jungbu Inland Expressway.
The bridge is located in Munkyoung, Kyoungsangbukdo. It is 490.8 m long, 12.6 m wide and consists of two structures, each with two lanes. Eight 50 m long spans form the bridge's main section and two 45 m long spans form the end sections. The segments used to construct the spans are 25 m long. This project was constructed on a turnkey basis by main contractor Taeyoung and Jeil Engineering Co.Construction of each segment required 9 days on average and included the following worksteps:
Re-bar Installation (with DSI Anchorage)
Sheathing Pipe Installation
Stressing (with DSI Equipment)
