View original description
Constructed over a 16-month period from 1931 to 1932, the undersea tunnel in Tongyeong is Asia’s first submarine tunnel. For its construction, the sea water was blocked at both ends, the tunnel was dug underground, and was paved with concrete. The Korean word “Yongmundalyang” engraved at the entrance of this 483-meter long, 5-meter wide tunnel means “the entrance of an undersea tunnel that connects island to land.”
