Highlights & Challenges

  • K2 Bridge will be the second cable stayed roadway bridge in New York City
  • As was the case with K1, final geometry was sorted out after IFC drawings were issued; cable anchor connection details were also modified along the way to suit a variety of fit up issues
  • There were over 33,000 shop attached studs that had to be coordinated with precast rebar locations that were not available until after modeling and edited drawings were complete
  • Complex modeling at the rocket launchers and girders
