The Alexander Hamilton Bridge Rehabilitation Project is the largest single-contract construction project in the history of the New York State Department of Transportation. This complex highway interchange project where I-95 and I-87 intersect involves many different elements of construction, including a full deck replacement as well as partial replacement and repairs to the superstructure and substructure of the bridge. Siefert Associates, LLC has played a vital role by designing two temporary ramp structures, for ramps 6A and 7A. In addition Siefert Associates, LLC provided construction engineering for substucture and lateral support, jacking plans and crane demolition and erection plans.
