Contractors completed installation of the 130-foot long, 19-foot wide Minto East Bridge deck in December 2015. Prior to delivery, Composite Advantage coated deck panels with Matacryl (aluminum oxide), a wear surface product which provides superior durability and environmental protection. Work on the Minto Bridge Center is expected to be completed in summer 2016.
Ottawa, Canada’s city engineers have chosen Composite Advantage’s (Dayton, OH, US) FiberSPAN, fiber-reinforced polymer composite bridge system for its update to its historic Minto bridges. The original truss bridges were built between 1900 and 1902. Composite Advantage says it won the competitive bid over fiberglass wood decking.
“Quick installation was another deciding factor because contractors were under a deadline to get the Minto Bridge East deck installed before winter weather set in,” said Scott Reeve, president of Composite Advantage. “Also, our products are integrated with features that make a contractor’s job easier and more cost effective.”
The FiberSPAN bridge deck system was prefabricated with bridge connection points, curb attachments and a shop-applied polymer concrete wear surface. In addition, deck panel thickness varied from 14 inches in the center to an exterior of 12 inches to provide a molded cross-slope for water drainage. Fourteen deck panels were engineered to meet 75 percent of the CL3-625-ONT service load (equivalent to a 16,600 lb wheel load) and an L/400 deflection requirement. The 130-foot by 19-foot bridge deck was supported by floor beams at a spacing of 18.3 feet.
