Construction
The main design and build contractor was Samsung C&T Corporation JV (Daelim, Daewoo, GS, Hanjin, Hanwha, Kumho). Total costs were {{KRW|2.45 trillion}},{{citation | url =weblink | title = Longest Bridge in Korea Opens to Traffic Monday | publisher = Wall Street Journal | author = Evan Ramstad | date = October 19, 2009 | accessdate = August 13, 2014 }} including federally funded approach roads. The {{convert|21.38|km|mi|adj=mid|-long|1}} highway project consisted of government-built sections at three ends and a {{convert|12.34|km|mi|1}} section in the middle built with private capital.The bridge section is {{convert|18.38|km|mi|1|abbr=on}} long. The bridge has a cable stayed section over the main sea route to Incheon port. This was the most difficult part to construct, with a main tower {{convert|230.5|m|ft|1|abbr=on}} high, vertical clearance of {{convert|74|m|ft|0|abbr=on}}, and five spans: a centre span of {{convert|800|m|ft|0|abbr=on}} flanked on either side by spans of {{convert|260|m|ft|0|abbr=on}} and {{convert|80|m|ft|0|abbr=on}}. Adjacent to the center section are approach spans consisting of a series of {{convert|150|m|ft|0|abbr=on}} balanced cantilever spans. Lower-level viaducts consisting of {{convert|50|m|ft|0|abbr=on}} spans connect to land at each end of the bridge. An arch span is located on the Incheon side of the bridge, which consists of two red-colored identical arches on each side of the bridge deck.Design
Because the bridge is situated in a known seismically active region, a seismic design of the substructure was adopted.WEB,weblink Incheon bridge, arup.com, 2011-01-02, At 12.3 km long, with a main cable stayed span of 800m, the new Incheon Bridge is one of the five longest of its type in the world. Its 33.4m wide steel/concrete composite deck carries six lanes of traffic 74 m above the main shipping route in and out of Incheon port and links Incheon International Airport on Yeongjong Island to the international business district of New Songdo City and the metropolitan districts of South Korea's capital, Seoul. The cable stayed section of the crossing is 1,480 m long, made up of five spans measuring 80 m, 260 m, 800 m, 260 m and 80 m respectively: height of the inverted-Y main towers is 230.5 m. A 1.8 km approach span and 8.7 km viaduct complete the crossing, both constructed with precast prestressed concrete box girder decks. Foundations are drilled piles 3 m in diameter.WEB,weblink Home, In order to accommodate movement between the bridge decks, the Incheondaegyo was equipped with expansion joints weighing up to 50 tons per joint.Notable incidents
On May 20, 2010, twelve passengers were killed in a bus crash at the bridge.In popular media
- Rough Cut: The bridge, under construction, was used as a backdrop for a fight sequence and appeared in promotional images for the film
