Route 22 traffic signal coordination project begins in Somerset and Union counties

NJDOT will improve mobility along the Route 22 corridor by interconnecting
18 traffic signals into one integrated system


(Trenton) – The New Jersey Department of Transportation (NJDOT) today announced the start of a congestion relief project, using technology to improve traffic flow along a thirteen mile-long stretch of Route 22 in Somerset and Union counties.

NJDOT will address Route 22 from milepost 36.45 (vicinity of I-287) in Bridgewater – through Bound Brook, Green Brook, North Plainfield, Watchung, Scotch Plains and Westfield – to milepost 50.25 (just east of the pedestrian overpass) in Mountainside.

The $7.77 million project will improve mobility along the entire corridor through the creation of an integrated system interconnecting eighteen traffic signals into one Controlled Traffic Signal System (CTSS).  This includes the complete replacement of the existing traffic signal systems at five intersections and geometric improvements and signal modifications to seven other intersections.

In addition, the project includes the installation of:

  • Eight new traffic cameras for the Camera Surveillance System (CSS).
  • Two new permanent electronic dynamic message signs
  • Fiber optic and wireless communication connecting the new integrated system to the Statewide Traffic Management Center in Woodbridge.

NJDOT’s contractor, Daidone Electric, Inc., has begun preliminary construction activity, including sign installation, field mobilization and directional drilling to install underground conduits this week.

As most of the improvements require the installation of electronic equipment outside the Route 22 mainline travel lanes, this work will be performed during normal business hours with minimal disruption to traffic.   All available travel lanes will be maintained on Route 22 during peak travel periods.  The proposed improvements at certain intersections will require temporary closures of the jughandle ramps to with traffic detoured along Route 22 to the next convenient intersection.  These detours will typically be limited to off peak hours and all travel lanes will be reopened during morning and evening rush hours.

The contractor plans to advance the improvements with multiple crews working simultaneously at different locations.  The project is scheduled for completion in summer 2014.

The precise timing of the work is subject to change due to weather or other factors.  Motorists are encouraged to check for real-time travel information.
