(New York, N.Y.) The replacement
of the Belt Parkway Bridge over Ocean Parkway was named the Design/Build Project
of the Year by the American Society of Civil Engineers (ASCE), Metropolitan
Gannett Fleming, an international planning, design, and construction
management firm, served as lead design consultant for the Granite
Halmar Design/Build Team completing the project.
The Belt Parkway Bridge, a regional corridor traveled by 166,000
vehicles daily, was rapidly deteriorating and nearing traffic capacity.
The New York City Department of Transportation needed to replace
the bridge and reconstruct the interchange ramps quickly, with minimal
disruption to the community in Brooklyn, N.Y.
Gannett Fleming overcame several challenges to complete this Design/Build
project. To meet an ambitious timeframe, the project team specified
extensive use of precast elements. The precasting took place in upstate
New York, saving the community from the noise and disturbance inherent
to a cast in place approach.
Designated as a New York City scenic landmark, the setting also
required substantial agency coordination to protect bridge architecture
and landscaping components. The resulting Belt Parkway Project added
capacity and a long lifespan for the bridge, while maintaining the
integrity of the parkway as a streetscape with a park-like image.
