The Incheon Bridge (Hangul인천대교; RRIncheon-daegyo) is a reinforced concrete 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, it is the world's seventh longest cable-stayed bridge as of October 2010. The bridge provides direct access between Songdo and Incheon International Airport, reducing travel time between them by up to one hour.

The section of the bridge crossing the sea, 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 JV (Daelim, Daewoo, GS, Hanjin, Hanwha, Kumho). Total costs were ₩2.45 trillion, including federally funded approach roads. The 21.38-kilometre-long (13.3 mi) 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.
