Project Details

This project involved the construction of four bridges to create a grade separated interchange to replace the Rt. 1 & Rt. 130 traffic circle. Due to the heavy traffic and hazardous conditions at the existing circle the NJDOT identified this project as a fast track project with high importance.

Three of the four bridges span over the Rt. 1 corridor. These three bridges consist of steel piles, 4’ diameter drilled shafts, poured in place concrete footings and columns, and a reinforced concrete deck supported by multiple steel girders (over 1,800 tons of structural steel). All deck concrete was high performance. The fourth bridge spans over Rt. 130, and was supported by two abutments constructed out of precast Mechanically Stabilized Earth Walls (MSE), and steel H-piles.

A total of nine MSE walls were constructed throughout the jobsite, ranging from 1,700sf to 13,700sf per wall. The project also required extensive earthwork and grading. Installation of roadway drainage, electrical systems, and water lines was also required on all three highways. Complete road reconstruction, including over 85,000 tons of Superpave asphalt, was installed throughout the jobsite. Much of the paving along Rt. 1, and the bridge construction over Rt. 1, was completed at night to minimize the impact on traffic.

The entire project was completed on a fast pace requiring coordination with the DOT and local authorities. We have received numerous awards and letters of appreciation from local residents and township officials. We also received a bonus from the NJDOT for completing the project successfully and ahead of schedule.
