Case Study: Bridge Traveler for the Kosiuszko Bridge

Built for Kiewit Construction under their engineering contractor Megatech Engineering

Bridge Traveler for the Kosciuszko Bridge

Since opening to traffic in 1939, the Kosciuszko Bridge, which carries the Brooklyn-Queens Expressway over Newtown Creek between Brooklyn and Queens, NY, has developed a reputation as a major bottleneck for motorists. To improve travel times and enhance safety, the New York State Department of Transportation replaced the existing 1.1-mile high-level truss bridge with a nine lane cable-stayed long-span structure as part of a $554 million design-build effort.

Movable Mobile Platform

Columbia Industries, LLC, worked in concert with Megatech Engineering and their contractor Kiewit Construction to design, manufacture and deliver the Bridge Traveler, a sizable project at over 80 ft. long, it was designed to span the width of the bridge and travel underneath the entire distance to provide a mobile platform for any future maintenance or repairs. It was designed and built with extendable aprons on either side so that the traveler can go from one end of the bridge to the other, and be able to go between the pylons for complete reach of the bridges underside.

AISC – Structural Steel - Quality

The project was awarded to Columbia Industries under the Made In America contract, and was chosen due to our ability to provide the qualifications standards under the American Institute of Steel Construction (AISC) quality in material and process. Over the span of a few months, Columbia quality assurance engineers kept the project on time and on quality.

Logistics – Prepped for Delivery

The project also required a compressed schedule as many other suppliers needed the bridge traveler in place to complete their projects. Columbia was able to transport the entire 80 ft load intact and on-time to our customers at the State of New York.
