This project involves various bridge repairs for 16 bridges in various towns of Nassau and Suffolk Counties (Final Design Phases V - VI) to prolong the service lives so that comprehensive bridge work would not be required for an extended period of time. Project locations include several bridges across and along the Long Island Expressway and Sunrise Highway. Work items include steel girder repairs, bearings replacements, concrete pier repairs, concrete patching, joints replacement, painting, etc. Design tasks include surveying and mapping, environmental studies, detailed highway design (V - VI), bridge repair design (V - VI), and project management.
B. Thayer Associates is responsible for developing work zone traffic control plans for the bridge inspection as per Manual on Uniform Traffic Control Devices (MUTCD) and its New York State Supplement. The B. Thayer Team is also conducting bridge inspection to address bridge elements such as abutments, wingwalls, approaches, girders, deck elements, and superstructure. Bridge inspection conforms with the New York State Department of Transportation Bridge Inspection Manual and with the Federal Highway Administration Bridge Inspector's Training Manual 90. Findings to date include fatigue, steel corrosion, concrete spalls, settlement, or other critical points; appropriate solutions have been recommended.
This project is on schedule and within budget.
