The city of Busan has approved the implementation plan for the Seunghak Tunnel private investment project and has published the topographical map, marking the beginning of the project. This Seunghak Tunnel is planned as a four-lane expressway with a total length of 7.69km, connecting the Eomgung Bridge in Eomgung-dong, Sasang-gu, to Chungjang-daero in Jung-gu.
The construction period is scheduled for 60 months from the start date, and If the city of Busan can commence construction in 2025, it aims to open in 2030. This project is expected to contribute to alleviating traffic congestion in Busan and promoting regional development.
The total project cost is 500 billion won (based on fixed prices), with a total investment amounting to approximately 622.5 billion won. Operations will be carried out for 30 years after opening.
