Suspended Deck Through Truss

View Exhibit map

Suspended deck through truss bridges (sometimes listed as an arch-truss) look very similar to a trussed through arch bridge, but they are not true arch bridges because they are continuous in design. By definition, an arch bridge cannot be continuous. As such, these bridges are essentially truss bridges with long, vertical suspenders that hold the deck below in place. Most examples of this kind contain a central main span that looks like a through arch, with a truss that transitions to a deck truss span on either side of the piers for the central span. Bridges added to this category must be continuous: simply-spanning examples are arch bridges and should not be listed here.
