BRIDGEWATER - State Department of Transportation officials announced a congestion relief project using new technology to improve flow along a 13 mile-long stretch of Route 22 in Somerset and Union counties.

NJDOT says the project is targeted at a section of 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 connect 18 traffic signals into one "Controlled Traffic Signal System." New electronic signs and traffic cameras are also part of the project.

Officials say the project is scheduled for completion in summer 2014.
