This large scale lift bridge is the modern replacement of the Burlington Swing Bridge, and is the third generation bridge at this location.
The bridge consists of a massive vertical lift span crossing the main navigation channel. This span was installed in 2011, and the remaining trusses were installed in 2012. These trusses are simple Warren through Trusses with riveted connections, and 10 panels a piece.
On the east side, 6 of these Warren Trusses approach the main vertical lift span. On the west end, a pair of deck girder spans serve as the approaches.
The bridge sits on concrete pile piers. The author has ranked it as minimally significant. If it did not cross a major river, it would be listed as no significance.
The bridge that this structure replaced could be considered a highly significant. As an 1890s Whipple Through Truss, constructed by George S. Morison; it was one of the last of his works left when demolished.
The photo above is a view from Polk Street. More photos of this structure will be coming soon.
