Reconstruction of Amwell Road (County Route 514) in Franklin Township, from Elizabeth Avenue westward to Wortman Street, will begin mid-March. Utility relocations in support of the project also will begin in March. An official start date will be provided when the date is more certain. Construction will continue through the end of 2020. 

The goal of the work is to make Amwell Road safer for all users. This project consists of the reconstruction of approximately 1.25 miles of roadway and will include new storm sewers, pavement widening and resurfacing, and upgrades to the two traffic signals located at Elizabeth Avenue and Mettlers Road. Although no new lanes will be added, wider roadway shoulders will be striped for bicycle lanes.

The majority of the work on Amwell Road will occur during the daytime.  One-lane closures will be necessary during daytime construction hours; flaggers and a temporary traffic signal will be utilized to alternate traffic.  Motorists should expect delays when construction starts and plan accordingly. 

Although one lane will be closed during the day, for the most part, the roadway will be fully opened to two-way traffic each night. There will be short periods, however, when the roadway will need to be fully closed at night to allow for work that cannot be performed otherwise.  Car and truck detours will be posted; motorists will need to follow posted detour signs during these periods.

A Public Information Center (PIC) was held for the project on March 28, 2019.  The vast majority of funding for this project is being provided through the New Jersey Department of Transportation (NJDOT) State Aid program. Somerset County will provide updates during construction to provide advance notice for staged traffic shifts and nighttime detour schedules.

Project Summary:

Somerset County has efforts underway to reconstruct Amwell Road, CR 514, because of several operational problems contributing to numerous traffic accidents along the corridor. The goals of the road work are to make the road safer and more effective by improving intersections and adding shoulders to aid with accident avoidance and aid in turning movements onto side streets and driveways. The improvements will address roadway deficiencies such as horizontal and vertical curvature impacting line of sight, pavement condition, and storm runoff collection that increase the risk of motor vehicle accidents.

 This project consists of the construction of approximately 1.25 miles of roadway reconstruction and associated drainage work. The proposed roadway width is 36’ wide to provide for 2 lanes, at 11’ wide each, and 2 paved shoulders, at 7’ wide each. The roadway will widen to 46’ wide for the two signalized intersections of Metlers Road as well as Elizabeth Avenue. The two traffic signals will be modified for compliance with current State and Federal standards.
