H&H is performing a complete biennial inspection for the Throgs Neck Bridge. Supported by two main cables with a span of 1,800 feet between towers, the structure has two side spans measuring 555 feet in length and contains two long approach viaduct structures, which connect to major arterial and local streets.

H&H’s scope of work for this investigation included overall management of the structural inspection of the Throgs Neck Bridge and associated ramp structures, as well as the National Bridge Element (NBE) Inspection of all structural elements (including fracture critical elements such as truss chords and gusset plates), load rating calculations and updates, inventory updates and report submittals. Supplementary tasks include design document preparation for structural repairs of elements requiring immediate repair, special interim inspections, and scoping studies for future projects related to the facility.
