This is the first undersea tunnel in the East built in 1932 after 1 year and 4 months. It is 483 meters long, 5 meters wide and 3.5 meters high. The breakwaters set on both sides of the sea are concrete breakwaters. It used to be the main link road connecting Tongyeong and Mireukdo, but with the opening of Chungmu Bridge and Tongyeong Bridge, it is almost no longer used.
