Construction and design must follow the International Building Code (IBC) as adopted by the City of Bellingham. The manufacturer must provide an integrated set of standard bridge components, including primary and secondary framing and accessories, and meet qualifications including AISC certification. Design details cover truss configurations, deck finish and placement limits, load cases, materials, welding, erection tolerances, and abutment/footing
