Route 78 Truck Weigh and Inspection Stations

Location: Warren and Hunterdon Counties, NJ


This project equipped the NJ Department of Transportation with the most modern, efficient vehicle inspection facility available. Several of our in-house divisions were involved in the successful completion of this four and half year job.

  • New building construction
    • Two completely new truck weigh stations were constructed supporting both local and remote vehicle inspections.
    • The buildings were designed to blend in to their surroundings by resembling large barns with attached silos.
  • Nearly two miles of heavy highway construction
    • Re-profiled roadway, widened and paved
    • Roadway lighting and 15 new sign structures were added along with 90 acres of roadway drainage.
  • Reconstruction of three bridges
  • 1.2 million CY of excavation

By far the most fascinating part of the project was the installation of the Weigh-in-Motion system. This technology enables vehicles to be weighed while traveling on the highway. A series of embedded sensors calculate the weight as the vehicle drives over a sensor pad. The dad is then related remotely to the control facility.
