Kosciuszko Bridge Phase I – Eastbound is the first cable-stayed roadway bridge in New York City. It services an estimated 180,000 vehicles per day.

Kosciuszko Bridge Phase I Scope of Work:

  • 3D modeling and shop detailing of approximately 2,700 tons of structural steel including floor beams, edge girders, pipe anchors and a full-length traveler system 46,000 shop attached studs

Project Stats:

  • NYSDOT’s largest design-build project to date
  • “K” Bridge 1 established statewide model for design-build projects
