Bridge Superstructure Replacements

NYS Route 960H over Catatonk Creek; Connection Road over Osborne Creek

NYS Route 960H over Catatonk Creek

Prudent Engineering's design team was retained as subconsultant to provide design services for the bridge superstructure replacement of New York State Route 960H over the Catatonk Creek in the Village of Candor in Tioga County, New York. The replacement superstructure is a 39’-2” wide, three-span continuous bridge totaling 230 feet in length. The project involved removing the precast box-beam primary members, eliminating the three simple-span configurations, and installing a steel multi-beam, three-span continuous superstructure system with precast deck panels. Prudent completed the following tasks for this project:

• Demolition & Removal of the Superstructure
• Substructure Modifications & Bearing Replacement
• Design of the Precast Deck Panels
• Structural Steel Design
• WZTC – Pedestrian Bridge Design
• Installation of New Approach Slabs
• Highway Approach Work
• Vertical & Horizontal Alignment
• Shop Drawing Review & Approval

Our team designed and detailed this fast-track project in less than four months to maintain the contractor’s tight construction schedule, which required this bridge be completed in 2015.
