Roads & Bridges Magazine Recognizes Gannett Fleming Project
December 2, 2009
 Route U.S. 1 & 9 and Rahway River Bridge(Mt. Laurel, N.J.) Roads & Bridges magazine selected the Route U.S. 1 & 9: Rahway River Bridge and Sections 1K & 3M Project as the #2 Road in its 2009 Top Roads List. The Top Roads List recognizes the best projects in road construction nationwide. Gannett Fleming, an international planning, design, and construction management firm, served as the lead designer on this project.
The Route U.S. 1 & 9: Rahway River Bridge and Sections 1K & 3M Project required improvements to vital infrastructure and the reconstruction of a historic bridge spanning the Rahway River. Using innovative methodologies and techniques, Gannett Fleming improved the roadway and safety conditions of Route U.S. 1 & 9, increased its capacity, and enhanced the overall infrastructure of central New Jersey.
As part of this award-winning project, Gannett Fleming performed preliminary assessments, site investigations, and remedial investigations; coordinated the disposal of non-hazardous waste; and prepared the associated reports. In addition, Gannett Fleming prepared a soil reuse report for the entire project corridor and property acquisition environmental cost estimate reports for impacted commercial properties.
One of the main goals of the project was to design two new bridges that would retain the historic signatures of the old bridge that spanned the Rahway River. The project team ensured that the important architectural features of the deck on the historic bridge were incorporated into the new designs. The completed structures are bridges that improve traffic flow for motorists while remaining true to the historical elements of the architecture.
Another important goal of this project was to improve Route U.S. 1 & 9’s roadway drainage. The existing roadway had an extremely deficient drainage system and was prone to frequent nuisance flooding. To solve this deficiency, the project team raised the roadway profile for Route U.S. 1 & 9 above the 100-year flood limit and installed two culverts sized for 100-year storm events. To prevent damage to adjacent wetlands, one of these proposed culverts was fitted with a control structure at the upstream end to maintain the depth of inundation in the adjacent wetlands.
