Overview

Opened in 1931, the George Washington Bridge is a vital travel corridor between New York and New Jersey, with an estimated 300,000 vehicles using the bridge every day. The bridge features 14 lanes of traffic on two levels in addition to with pedestrian and bicycle lanes.

We performed biennial inspection of the George Washington Bridge New York approach roadways, in addition to Henry Hudson Parkway ramps and retaining walls, that was completed in 2017.

Highlights

  • Field teams inspected 17 bridges, with 156 spans consisting of prestressed, post-tensioned concrete, reinforced concrete T-beams and multigirder structures, nine retaining walls, and sign structures.
  • We designed repair details for immediate action conditions and performed Level 2 load-rating updates. All work was performed in accordance with Port Authority of New York and New Jersey and New York State Department of Transportation guidelines.
  • We were also able to overcome complex logistical issues to facilitate the successful completion of this challenging inspection project on time and within budget.
