Incheon Bridge Size report

Incheon Bridge is the second-longest bridge in South Korea. Construction of the bridge started in July 2005, with a total investment of 1.4 billion U.S. dollars. It took more than four years to complete and open to traffic on October 16, 2009. Large capital investment and long periods are enough to show the grand scale of this bridge.
