Thank goodness for BridgeHunter-1972 comments. I assumed this bridge was a trunnion bridge until I read the comments. It is a lift bridge! The span is pushed up from below. The photos below from a rehabilitation in 2012 provide insight. "The rehabilitation process included removal of the approach decks, the lift span structural steel, hydraulics, and machinery. The design included new lift span structural steel, new steel grating, new concrete approach decks, new traffic impact gate arms, new hydraulics, and rehabilitated machinery. Other design features include new railings, walkways, bike plates, concrete stain, navigational bumpers underneath the bridge, new system controls, and lighting. New asphalt roadway approaches to North Water Street and North Palmer were also constructed." [
