Composite Advantage (Dayton, OH, US) says its FiberSPAN’s FRP cantilever sidewalk system is gaining momentum among bridge owners as it offers a lightweight corrosion resistant option for sharing the road with pedestrians.

“Even if a vehicle bridge has a sidewalk, it’s typically just 3 ft. to 4 ft. wide, which is too narrow to support the volume of bicycle and pedestrian traffic communities are seeing today,” said Scott Reeve, president of Composite Advantage. “It’s prohibitive to take additional space from vehicle lanes. Dead load weight limitations rule out 10 ft. wide concrete sidewalks and installing a separate bridge is costly.”

The FiberSPAN-C deck is typically 20% the weight of reinforced concrete, which significantly reduces the dead load on the vehicle bridge. Connection options include supports at piers for a small superstructure or gussets that act as floor beams at diaphragms or trusses. Railing attaches directly to the FRP decking. Components are prefabricated for accelerated construction and lower installation costs. Functional features like a non-slip wear surface, drainage scuppers, grating, curbs, light posts and electrical boxes are added during fabrication.
