Tsunoshima bridge, Japan.
The 780m long Tsunoshima Bridge was the longest toll-free bridge in Japan. Since then a longer bridge has been built in Okinawa.
Tsunoshima is just off the coast of north eastern Yamaguchi Prefecture. A little over 4 square kilometers in size, and with a coastline of 17 kilometers, less than 1000 people live there, but the bridge cost a staggering 15,000,000,000 yen, which works out at about 150,000 USD per inhabitant.
Tsunoshima means “Horn Island” and refers to the shape of island like a pair of cow horns. Cattle have been raised here since the eighth century.
