<p>Although four suspension bridges have already been built in Korea, constructing the Yi Sun-sin Bridge is a great challenge not only because its main span length of 1545m is almost three times as long as the previous longest suspension bridge in Korea, but also because it is the first suspension bridge for which Korean engineers solely carried out all of the construction tasks, creating their own equipment and devices for the cable erection process as well. In this paper, several unique features pertaining to the cable erection procedures are introduced instead of the details of ordinary cable erection procedures, which are not very different from those of other long-span suspension bridges. An improved spinning wheel, a wire supply method for the spinning of extra- strands, and a band-hanger installation method are described.</p>

<p>This paper presents analysis and construction method of the Sorok (self-anchored suspension) bridge that is currently under construction in the Sorok Island, CheonllaNamdo, Korea and expected to be completed in 2008. To find the optimum initial equilibrium condition of self- anchored suspension bridge, the force of main cable and hanger are developed together with minimizing vertical camber of stiffening girder. Erection stage analyses are carried out for both hanger-pulling method and girder jack-down method to find out the more effective one which ensure the erection stability and cost efficiency. Hanger-pulling method is adopted as the erection scheme of suspension system as a result of the study. Various measurement results at site show that analysis results are well matched up with bridge deformation and girder profile during construction and at ist final stage and have a good correspondence with the original design profile</p>

<p>The Yi Sun-sin Bridge connects the cities Yeosu and Gwangyang in Korea. The link provides easy access between Yeosu and the Gwangyang Industrial Complex. It is a suspension bridge with the main span of 1545m carrying four traffic lanes. This paper gives a description of the deck erection method adopted for this bridge. Emphasis has been put on the erection of a girder using a winch- driven lifting gantry.</p>
