These documents are construction drawings and technical specifications for the Skiway Avenue Bridge Superstructure Replacement project, prepared by C.S. Gannison, Inc. for Washington Township in Franklin County, Pennsylvania. The project involves replacing the superstructure of the Skiway Avenue Bridge (T-808) over Red Run, which is a single-span, composite steel I-beam bridge. The design includes complete replacement of the existing bridge superstructure, with detailed plans for a new 1-span steel I-beam bridge, including structural elements like beams, deck, bearings, barriers, and abutments. The bridge will have a clear roadway width of approximately 17-1/2 feet and will be constructed using detailed engineering specifications for materials, construction methods, and structural components.

The technical drawings provide comprehensive details for construction, including structural plans, elevation charts, rebar schedules, bearing seat details, and specifications for materials like steel beams, concrete, elastomeric bearing pads, and reinforcement. The project includes precise measurements for beam elevations, deck thicknesses, and structural components, with specific attention to engineering standards and construction tolerances. Additional documentation covers soil erosion control, seeding restoration, maintenance programs, and standard construction details for elements like concrete washout, temporary cofferdam, and pump bypass systems. The drawings are dated for a potential construction timeline and include detailed technical specifications to ensure precise implementation of the bridge replacement project.
