The most optimized shape in the industry. CON/SPAN’s innovative, economical design stands apart from any other system. Its distinctive arch action which utilizes fast, set-in-place construction, has been optimized, providing the ideal blend of hydraulic efficiency and structural capacity. A legacy of innovative technologies blended into the optimized CON/SPAN O-Series cs-oseries-logoThere are over 7,000 CON/SPAN B-Series installations since 1983. CON/SPAN Bridge Systems have been used by more state DOTs than any other system. With a history of innovation and experience, Contech has taken precast buried bridge systems to the next level with the optimization of the CON/SPAN® O-Series™. Requiring less concrete per open area than any other precast buried bridge structure, the O-Series is the ideal blend of hydraulic efficiency and structural capacity. Spans range from 12’ to 65’. Buried Bridge Structure - Reduces maintenance costs and lowers life cycle costs as there are no bridge deck or joints at the deck/roadway interface. Modular Bridge System - Rapid installation results in reduced overall project costs, delays and detours. Designed “Site Specific” - Meets your site needs in full compliance with AASHTO and AREMA design standards for highway and railway use. Lighter piece weights or longer lay lengths for most projects. Outward horizontal reactions – one-sided keyway, reduced forming and grouting Maximized clear span and clear distance between footings PROVEN design methodology Total reliabilty
