Tokyo, Japan's Bridges: Arakawa High Capital Bridge

March 2012 (35.699 Degrees, 139.857 Degrees) Arakawa High Capital Bridge
The next bridge downstream carries Route 7 of the Metropolitan Expressway. Its called the Arakawa High Capital (or Komatsugawa) Bridge (maybe because that's the name of the town in Edogawa Ward). The bridge is a unique, three span (two tower) cable-stayed bridge with only four cables. The towers are short and the cables are low, so maybe it's more of an extrados bridge. I don't understand why the towers continue so far above the cables. Maybe the top of the towers is for tuned mass dampers? Maybe they were going to have a third set of cables but decided they didn't need it?

The bridge has steel towers, steel girders, and concrete piers.  As I've mentioned several times, I don't like it when the towers don't match the piers.
