The bridge was built by contractor Daelim Industrial Co. Ltd for client Iksan Regional Construction & Management Administration.

A 1,300 ton floating crane was used to install the caisson foundations, which was cheaper and did not interfere with shipping at the site.

Cast-in-place concrete piles were chosen for PY2 because the shallow depth of just 3.9m restricted access by the floating crane.

Construction of the pylon legs was carried out using automatic climbing system formwork, in lifts varying from 3m to 4m height.

When the climbing form reached a height of 72.9m, the concrete edge girder was installed by the form traveller supported by permanent stays was chosen – this self-launching system is designed for in situ casting of the segment using the free cantilever method.

The approach viaduct is 280m long, with 8 spans of 35m in length consisting of post-tension beams and cast-in-situ slabs.
