Kosciuszko Bridge Phase I – Eastbound

CLIENT: High Steel Structures
LOCATION: Brooklyn and Queens, New York City
project overview:

The original K-Bridge, overlooking Newton Creek, was built in 1939, connecting the city of Brooklyn with Queens, New York. Phase I of this project was the addition of a new and first Cable-Stayed Bridge in New York City that carries an estimated 180 000 vehicles per day, in both directions until Phase II. The new bridge, designed by HNTB and constructed by the joint venture of SKE (Skanska-Kiewit-ECCO III) by  has 2-single pylon designs with a 1000-ft main span, a 20-ft wide bike-lane/walkway, and five standard lanes for Queens-bound traffic. A lighting design system was also included to light up the towers at night.

Kosciuszko Bridge Phase I Scope of Work:

  • Working with High Steel Structures, DBM Vircon provided 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:

  • New York State Department of Transportation’s largest design-build project to date
  • “K” Bridge 1 established a statewide model for design-build projects
  • Single pylon design with main span of 1000-ft supported by 56 cables in total
  • 4,000-short-ton (3,600-long-ton) counterweight built under western section since the eastern section was longer and heavier
  • Aesthetic colored lighting design system that will allow for dynamic light shows to illuminate the stay cables and pylon towers at night
  • 100-year service life

Kosciuszko Bridge Phase I Project Highlights & Challenges:

  • The design-build contract was NYSDOT’s largest ever, and one of its first design-build contracts
  • Modeling of the cable supports and finalizing geometry while the project was still being designed
  • Coordinating shop welded studs with the precast panels
  • Complex modeling at the rocket launchers and girders
  • Coordinating with the design team as the job was released in design unit portions
