Bronx-Whitestone Bridge

The Bronx-Whitestone Bridge is the 23rd-longest main suspension bridge in the World and carries more than 110,000 vehicles per day. This bridge crosses the East River, connecting the Ferry Point Park area of the Bronx with the Whitestone area of Queens.


WSP USA, formerly WSP | Parsons Brinckerhoff, has performed biennial and special inspections of this structure utilizing multiple inspection teams. Inspectors utilized a variety of access methods that included high lifts, bucket trucks and underbridge inspection units, free climbing, and necessary MPT. The inspection was performed in a busy urban local and involved the coordination of contractors, other consultants and Triborough Bridge and Tunnel Authority (TBTA) facility and maintenance personnel. WSP has prepared the NYSDOT Biennial Inspection Report and Steel and Concrete Detail Vulnerability Assessments as well as the Authority’s Narrative/Summary Report and Paint Condition Report.

Additionally, WSP was contracted to develop schemes for performing maintenance repairs to the Bronx Whitestone Bridge Queens Approach Superstructure. This component repair contract consisted of reviewing existing data, developing a work plan, designing structural repairs and providing contract drawings and specifications. The Queens Approach was scheduled to be replaced only after the Bronx Approach was replaced and it was necessary to maintain the strength and integrity of the Queens Approach, before its scheduled replacement, which may take up to 10 years. The proposed repair recommendations were developed to upgrade and maintain, wherever possible, the targeted component rating to as close as HS 25 based on a fiscally responsible repair and strengthening methodology.

We also provided construction management & inspection services for concrete repairs at the Queens Anchorage & rehabilitation of the Bronx & Queens eyebar chambers at the Bronx-Whitestone Bridge. The projects involved concrete repairs to the Queens Anchorage; and cleaning and oiling the cable strands in the Bronx and Queens Anchorages, cleaning, painting and greasing the eyebars in both anchorages as well as cleaning and installing new lighting in each eyebar chamber as well as installing a concrete floor in the Queens Anchorage.
