Hamana Bridge

The Hamana Bridge spans 631.8 meters across Lake Hamana's entrance to the Pacific Ocean with a central span of 240 meters.

Upon its completion in 1976, the Hamana Bridge held the world record for the longest plate girder bridge span until newer structures surpassed it.

The bridge connects communities around Lake Hamana, Japan's tenth largest lake, which transformed from a bay into a brackish lake after the 1498 earthquake.

The speed limit on this automobile-only bridge is 80 kilometers per hour, with pedestrians and bicycles prohibited from crossing.

The bridge remains unlit at night to protect the local shirasu fishing industry and preserve the nesting habits of loggerhead sea turtles.
