Excavation work has been completed on Korea's longest undersea tunnel.
The Boryeong Undersea Tunnel runs between Daecheon port in Boryeong, Chungchungnam-do Province and Wonsan-do Island.
The six-point-nine kilometer tunnel will be the 5th longest undersea tunnel in the world.
The project includes the undersea tunnel, which is expected to open by the end of 2021, and a bridge connecting two islands which is set to open later this year.
It will cut travel time between Boryeong and Taean from the current 90 minutes to just 10 minutes by car.
