First Span Opens

Motorists travelling on the Brooklyn-Queens Expressway are now making the trip over Newtown Creek on the new single tower cable-stayed Koscuiszko Bridge designed to accommodate traffic levels that far exceed the capacity of the original bridge that opened in 1939. The new bridge opened to traffic on April 27, 2017, becoming the first new bridge to open in New York City since the Verrazano Bridge in 1964.

An estimated 180,000 vehicles per day use this 1.1-mile segment of the Brooklyn-Queens Expressway. As one of New York City’s few north-south interstates, the original Kosciuszko Bridge could not efficiently handle the present volume of traffic due to its narrow lanes, steep grades, lack of shoulders, and short merge/weave distances near ramps and interchanges, which did not meet current highway design standards.

WSP has played multiple key roles throughout the design and construction of the bridge on behalf of the New York State Department of Transportation (NYSDOT). The firm provided design and engineering services that included structural alternative analysis, preliminary engineering, development of design-build procurement documents, design oversight and quality assurance, bridge/structural engineering, civil engineering, development of work zone traffic control plans, demolition engineering, landscape design, building design, geotechnical/seismic design, environmental mitigation/remediation and construction support services.

WSP is the owner’s engineer for Phase 1 of the project and provided design quality assurance and design oversight for the design-build contract and an independent check of the cable-stayed main span design.

The first span will ultimately carry eastbound (Brooklyn-bound) traffic. The design-build contract was NYSDOT’s largest ever, and one of its first design-build contracts.

The new (Kosciuszko) Bridge provides New York City with a signature structure connecting Brooklyn and Queens. Single tower cable-stayed bridges like this are uncommon, and this has the distinction of being the first cable-stayed bridge in New York City.

Work Under Way on Phase 2

WSP is the engineer of record for the Phase 2 contract, which began in the fall of 2017 following the demolition of the remaining original bridge in late September.

Phase 2 of the project is being completed as a traditional design-bid-build project, with WSP providing final design services. The structure includes a single-tower cable-stayed main span and prestressed girder approach spans.

Design work for the $318 million second span, which will ultimately carry westbound (Queens-bound) traffic, was completed in May 2017. The bridge is targeted for completion by late 2019.

When completed, the new bridge will provide a 20-foot-wide bikeway/walkway across the bridge, aesthetic lighting, local street realignments and streetscaping. The new crossing has been designed for a 100-year service life. It also features an aesthetic lighting design that will allow for dynamic light shows. It is the first structure to implement New York Governor Andrew Cuomo’s lighting initiative, which promotes the use of energy-efficient LED lighting on infrastructure projects.
