Incheon Bridge
The Incheon Bridge (also called the Incheon Grand Bridge) is a newly-constructed bridge in South Korea. At its opening in October 2009, it became the second connection between Yeongjong Island and the mainland of Incheon. The Incheon Bridge is South Korea's longest spanning cable-stayed bridge. In comparison, the Incheon Bridge is the world's seventh longest cable-stayed bridge as of October 2010. The main purpose of the bridge is to provide direct access between Songdo and Incheon International Airport, reducing travel time between them by up to one hour. The sea crossing bridge section, whose concessionaire is Incheon Bridge Corporation, is funded by the private sector. Korea Expressway Corporation and the Korean Ministry of Land, Transport and Maritime Affairs (MLTM) managed the project.

The main design and build contractor was Samsung C&T Corporation. Additional contractors that contributed to the construction of the bridge were Halcrow, Dasan Consultants, and Arup. Total costs exceeded $1.4 billion (~1.25 trillion KRW) to build. The 21.38 kilometres (13.3 mi) long highway project consisted of government-built sections at three ends and a 12.34 kilometres (7.7 mi) section in the middle built with private capital, the bridge section is 18,384 metres (60,315 ft) 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 230.5 metres (756.2 ft) high, vertical clearance of 74 m (243 ft), and five spans: a centre span of 800 m (2,625 ft) flanked on either side by spans of 260 m (853 ft) and 80 m (262 ft). Adjacent to the center section are approach spans consisting of a series of 150 m (492 ft) balanced cantilever spans. Lower level viaducts consisting of 50 m (164 ft) spans connect to land at each end of the bridge.

Because the bridge is situated in a known seismically-active region, a seismic design of the substructure was adopted.

Unfortunately, several complaints have been submitted regarding the absence of an off-ramp prior to the bridge. As a result, hundreds of commuters have accidentally had to take the bridge, pay the toll of 5,500 South Korean Won, get back on the bridge and pay the toll a second time. Investigations are ongoing regarding the intentional absence of off-ramps during construction to increase toll revenues. The CEO of the Korea Expressway Corporation refuses to comment on the issue.
