As locals stretching from Commack to Mount Sinai get set to endure years of gridlock on Route 347, the state's Department of Transportation on Monday announced it will install traffic information signs along the North Shore artery telling drivers just how long the waits will be.
The 347 corridor is being rehabbed into a greenway, complete with new lanes, bus stops, tree-lined medians and a bike and pedestrian path that will run the length of the roadway. The state has already completed the section in Hauppauge at the start of highway through to the Route 111 intersection. The project could take more than 10 years to complete.
According to the state, electronic signs showing travel times to various roads and intersections are being set up along the 15-mile stretch, including Route 111, Route 25, County Road 97, NY Route 112 and County Road 83.
The state uses sensors placed on the road to calculate travel times.
The second phase of the project is underway from Wheeler Road/Route 111 to Mount Pleasant Road in the Smithtown/Hauppauge area, adding a third travel lane in each direction. Residents in that area have voted to have sound barrier walls, similar to those along the Long Island Expressway, built to shield residential homes from the noise of construction and passing traffic.
State workers are also reconstructing the Route 347 and Route 112 intersection in Port Jefferson.
