Route 206 Bypass project begins Hamilton Road Bridge construction

Hamilton Road to be closed and detoured as bridge is built

(Trenton) - The New Jersey Department of Transportation (NJDOT) officials today announced the start of work on the Hamilton Road Bridge that will cross over the Route 206 Bypass roadway in the vicinity of Old Somerville Road as the Route 206 Hillsborough Bypass project advances in Somerset County.

Beginning at 9:30 p.m., Wednesday, March 6, NJDOT’s contractor, Konkus Corporation, is scheduled to close Hamilton Road to begin the construction of the Hamilton Road Bridge and complete the portion of the Route 206 Bypass roadway underneath it. Hamilton Road will be closed for approximately one year. Old Somerville Road, between Hamilton Road and existing Route 206, will remain open for the duration of this closure.

The Hamilton Road Bridge will be approximately 150 feet long, elevated 10 to 15 feet, and carry one lane of traffic in each direction. A six-foot wide pedestrian walkway also will be built on both sides of the bridge.

Route 206 Bypass
When completed, the Route 206 Hillsborough Bypass will shift through traffic onto a new 3.6-mile section of Route 206 to the east of the existing highway between Mountain View Road and Old Somerville Road, creating opportunities for the development of a town center along the current Route 206 in Hillsborough.

The 1.7-mile center section of the Bypass was built first as part of a $44 million state-funded contract. It was completed and opened in October 2013. Since then, utilities have been relocated, trees cleared, and grading and drainage work was completed on both ends of the project.

The $36.6 million state and federally-funded Contract B will construct the remaining portion of the Route 206 Bypass. The project limits are from Mountain View Road to Hillsborough Road on the southern end and from Amwell Road (CR 514) to Old Somerville Road on the northern end. A jughandle ramp will be constructed on the northeast corner of the Route 206 and Triangle Road/Falcon Road intersection. Construction is anticipated to be completed by fall 2020.

In addition to the Hillsborough Bypass, NJDOT is advancing two other projects to improve Route 206 in Hillsborough in the next several years. These projects are designed to improve safety and reduce congestion through the township by widening approximately two miles of Route 206 north of the Bypass. Details about the other two projects are below:

Route 206, Doctor’s Way to Valley Road

  • The project will widen the existing Route 206 from one lane in each direction to two lanes in each direction between Doctor’s Way and Valley Road, which is just north of where the Route 206 Bypass will begin (Old Somerville Road)
  • Design activities and acquisition of property for the project are currently underway
  • Construction is anticipated to start in summer 2020 and be completed by fall 2022

Route 206, Valley Road to Brown Avenue

  • The project will continue widening the existing Route 206 from one lane in each direction to two lanes in each direction between Valley Road and Brown Avenue
  • Environmental work and supporting design activities for the project are currently underway
  • Construction is anticipated to start in 2022 and take approximately two years to complete

Variable message signs are being utilized throughout the project limits to provide advance notification to motorists of all traffic pattern changes associated with the bypass project. Throughout the project, NJDOT will provide information before upcoming road or ramp closures.

The precise timing of the work is subject to change due to weather or other factors. Motorists are encouraged to check NJDOT's traffic information website www.511nj.org for real-time travel information and for NJDOT news follow us on Twitter @NJDOT_info and on the NJDOT Facebook page.
