Brandywine Road Bridge Over Brandywine Creek
Summit County Engineer | Northfield Township , Ohio
Osborn served as the Engineer of Record for the rehabilitation of Brandywine Road Bridge over Brandywine Creek for the Summit County Engineer. The project involved preparation and design of construction plans for the rehabilitation of SUM-CR40-01.57 (SFN 7746032) carrying Brandywine Road over Brandywine Creek in Northfield Township, Ohio. The bridge is a 3-span continuous steel beam bridge with concrete substructures. The project included replacement of the existing deck with a composite reinforced concrete deck, replacement of existing bearings, expansion joints, bridge railing, and approach slabs. Osborn performed a hands-on field inspection to sound the existing concrete substructures to identify delaminated areas in need of repair. In addition, we also observed the existing steel beams to determine if any structural steel repairs were necessary. Included with the design was evaluation of the existing bridge to be converted to semi-integral in order to alleviate the need for maintenance prone expansion joints. During preliminary design, Osborn evaluated the existing pier substructures to determine if they met current design loading requirements or if a design exception would be required. The bridge is on a horizontal curved alignment, with straight beams and dog-leg just south of the north pier. The new concrete deck follows the curved alignment of the roadway, matching the existing. Roadway work was minimal and include replacement of the existing approach guardrail with new MGS to meet current standards. The proposed bridge was constructed full-width with traffic detoured for the full construction duration.
