Two shores of Tokyo Bay were linked Monday by the world’s longest stretch of undersea highway.
In a nationally televised ceremony, officials celebrated the completion of drilling work on the “Aqualine” expressway.
The new highway - which isn’t yet open to traffic - spans nine miles, roughly two-thirds of it below Tokyo Bay. The remainder is a three-mile bridge.
The highway, which is estimated to cost $12 billion, is scheduled to open in December.
