The New York State Department of Transportation (NYSDOT) has completed a repaving project of more than four miles of road along the Long Island Expressway (LIE/I-495) in Western Nassau County, including those in Roslyn Heights.
NYSDOT officials said that the $9.5 million project between the Nassau/Queens line and Willis Avenue/Exit 37 in Roslyn Heights improves the safety of more than 200,000 drivers who use this section of the LIE each day.
The project involved removing the worn top layer of pavement from over four miles of all eastbound and westbound LIE main line travel lanes, making needed base repairs and then resurfacing the roadway with new asphalt overlay. Construction included providing new pavement markings, audible roadway delineations to help prevent off-road drifting, and replacement of vehicle detectors and traffic loops to help alert the public about current LIE traveling conditions via the INFORM transportation management center (TMC).
Construction was performed in stages on shorter sections of the LIE and during off-peak, nighttime hours and one direction of the LIE remained opened at all times. Drivers were warned in advance of the closures via NYSDOT’s INFORM traffic management electronic signs and those motorists who could not use alternate routes were detoured to the LIE north or south service roads where traffic signal timing was adjusted to maximize the flow of detoured traffic.
