SpaanSpan ™ A Precast Concrete Through-Girder Bridge System Improves under-clearance Low Profile Structure Increases Under - Clearance Minimizes approach work Post-Tensioned Edge Girders Can accommodate skews Variable deck widths possible Precast Drop-in Deck Panels Greater internal redundancy Safety barrier protects edge beams on the Hook Road Bridge in Rochester, NY. High resistance to impact SpaanSpan™ bridges are jointless and post-tensioned in transverse and longitudinal directions. Combining the strong performance of post-tensioning with quality precast concrete promises low, long-term maintenance costs.
