Flashback Friday: Alexander Hamilton Bridge Rehabilitation

In 2012, Siefert Associates, LLC provided construction engineering services to Halmar International and China Construction America Inc. as part of the rehabilitation of the Alexander Hamilton Bridge in Manhattan and the Bronx, NY. This complex highway interchange project where I-95 and I-87 intersect involved 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. SALLC played a vital role by designing two temporary ramp structures, substructure and lateral support, jacking plans and crane demolition and erection plans.
