The Burnside Bridge has an unmatched lineage. Its moving parts were designed by Joseph Strauss, who also engineered the Golden Gate Bridge. And its overall design came from the "dean of American bridge engineers" (although he was from Czechoslovakia), Gustav Lindenthal, who was commissioner of bridges in New York City. Among his many spans, he designed the Hell Gate (the world's highest arch bridge) and the Manhattan Bridge.
The Burnside's most recognizable features are its two cantilevered control turrets and their decorated roofs and bottoms. It crosses the narrowest part of the river downtown. Two huge concrete counterweights (1,700 tons each) in the main piers allow it to open up, swinging two 133-foot sections vertically. Since all that weight rests atop wooden pilings down below, don't expect the Burnside to be around forever.
