That's an unusual design. I don't recall seeing other bridges that gradually transition from a through truss to a deck truss. I wonder why they did it.

Actually, it is the 1999 bridge that replaced the Helen Keller drawbridge. Steamboat Bill supplemented the drawbridge and carried northbound U.S. 31/eastbound U.S. 72A traffic until the newest bridge was built; it now is the southbound/westbound crossing.
