The Seneca style is a beautiful curved shape that adds to the efficiency of the bridge. The trusses each have a continuous arched top chord, a single diagonal member in each truss panel, and a vertical member at each interior bottom chord panel point. The bottom (tension) chord of each truss consists of two equal-sized members with adequate section properties to provide redundancy. The Seneca style offers many benefits, thus making it a preferred bridge. This bridge has an all-bolted construction option, which allows for easy on-site erection. It also has upper bracing that supports for longer length spans of up to 300′. Further, there are galvanized or self weathering finishes available. Lastly, the Seneca bridge guarantees a life span of 100+ years. Download Full Specs View 3D Seneca Bridge Model Download 3D PDF Must have Adobe Acrobat. Click here to download.
