Tokyo, Japan's Bridges: Clover Bridge (クローバー橋) across the Onagigawa (2)

March 2012 (35.685 Degrees, 139.821 Degrees) Clover Bridge
A last look at the Clover Bridge. From this view we can clearly see one of the four abutments with unusual interior shear keys to resist lateral movement (from collisions or from earthquakes).

Collision protection systems have become more sophisticated, but a heavy barge travelling at 10 knots has too much momentum to be stopped by any energy dissipation system.

This area of Tokyo is full of art museums and historical artifacts. The Japanese are careful to preserve the past. After the 1995 Kobe Earthquake, the city left damaged lampposts and damaged bridge columns in place with placards to remind people of what had happened.
