Lettiere announces completion of Route 179
Hyperbuild project
NJDOT installs West Amwell bridge in four months

(Trenton) - Commissioner Jack Lettiere today announced the successful completion of the New Jersey Department of Transportation's (NJDOT) second Hyperbuild initiative project. NJDOT installed and rehabilitated a bridge on Route 179 in West Amwell, Hunterdon County.

The application of Hyperbuild concepts enabled NJDOT to install the bridge in four months, saving 21 months and $520,000.

"Hyperbuild enables NJDOT to reduce traffic congestion, improve safety and save taxpayer dollars," said Commissioner Lettiere.   "NJDOT under the Hyperbuild initiative has replaced bridges more cost-efficiently and quickly."


NJDOT followed an aggressive schedule and used an unconventional detour route to complete the majority of the construction during summer 2005, minimizing the project's impact upon those traveling to and from nearby West Amwell Elementary School and South Hunterdon Regional High School. NJDOT expedited construction by employing a detour route on adjacent Route 202 and allowing only one lane of traffic to travel in a single direction through the construction area.


NJDOT reduced the project's design and construction time by salvaging the bridge's original abutments and piers and reconstructing only 50 feet of roadway. H & G Contractors of Ridgeway, NJ installed the new bridge beams, deck and guide rails and rehabilitated roadway approaches. This shortened construction duration, making the new bridge usable more quickly and with minimal disruption to motorists.


NJDOT typically would complete a project of this magnitude in approximately 25 months using traditional deck replacement and bridge rehabilitation methods.


The rehabilitation of the Route 179 Bridge using Hyperbuild enabled NJDOT to more quickly improve motorist safety and minimize the project's environmental impact. Prior to its replacement, the 76-year old Route 179 Bridge was in poor condition due to the wide cracks in its underside.   Its concrete railings were flaking and its reinforcing steel beams were deteriorating.


The Route 179 Bridge spans Alexauken Creek, an environmentally sensitive stream, and is located within the Mt. Airy Historic District. NJDOT initially planned this project as a total bridge reconstruction, which would have required major permits and environmental coordination. NJDOT then streamlined the design and construction process to save time and reduce the project's impact upon the environment.  


More than 5,000 vehicles use the Route 179 Bridge daily. NJDOT projects that in 15 years approximately 50 percent more vehicles will use the bridge.


NJDOT currently is employing Hyperbuild on thirteen additional projects statewide.
