Sambo Engineering, in consortium with Hyundai Construction, was chosen to perform the alternative design for additional construction of the Lot 13-4 of the Gyeongbu High-Speed Railway, based on the strength of the submitted bid design.
The original project planning met with substantial public opposition. Priority in the alternative design was to respond to this opposition. Additionally, the alternative design needed to satisfy the requirements of protecting the ecology of the surrounding wetlands, cultural artifacts. The importance of minimizing disruption to these during construction has increased.

The project section was located in the Yangsan area of Gyeongsangnam Province, and had a 4.825km of track, in addition to the total length of 13.28km of the Wonhyo Tunnel.
