Abstract

The New Millennium Bridge, located on the southern coast of Korea, is a multiple span suspension

bridge with two 650m-long main spans. Distinguished from other suspension bridges constructed

for the last decade in Korea, this bridge is the first multi-span suspension bridge. In this paper, two

distinctive features in the stiffening deck erection are introduced: (1) the unbalanced sequence for

lifting the stiffening deck blocks and (2) derailment prevention system of the block lifting device

(also known as lifting gantry).

Keywords: multiple-span, suspension bridge, stiffening deck, lifting gantry.
