The Incheon Bridge, bridge currently under construction, will become the second connection between Incheon and Yeongjong Island, in South Korea. It will be finished in 2009. The Incheon Bridge will be 18,2 km long, of which the most difficult part will be cable-stayed bridge portion over the main sea route to Incheon port. The Incheon bridge’s budget is estimated to over $2.5 billion.
The foundations will be drilled cast in place piles and the bridge pylons will be Y-shaped concrete structures. The main bridge span is designed for the safe passage of shipping under the bridge. The approach bridges will be constructed using the pre-cast concrete segmental method including the girders and pier caps, while the viaduct bridges will be constructed by the full span precast launching method. Load-testing for the 3m drilled shafts for piling were completed to a standard of 210,000kN in February 2005.
The 33.4m-wide bridge will support three lanes in each direction across the span and will include manual and electronic toll booths on the island side.
