Long Island Expressway service roads closing to add signs

Service roads along the Long Island Expressway in parts of Nassau County and throughout Suffolk will be closed over the next four weeks from 9 p.m. to 6 a.m. Sunday to Thursday while signs are replaced with new, high-reflective ones.

The work, part of a $7.4 million project performed by Jericho-based Mana Construction Group under contract to the New York State Department of Transportation, began Tuesday in the Town of Oyster Bay on the eastbound service road south of the expressway, said department spokeswoman Eileen Peters.

Once completed through to Exit 73 in Riverhead, westbound operations north of the expressway will start and continue all the way to the Nassau/Queens border.

To reduce the impact on motorists, there will be no lane closures in the westbound direction on Sunday nights. In addition, only small sections of the service roads are being closed at one time.

Already, obsolete lamp-lit highway signs have been replaced with more visible, high-reflective signs on the LIE mainline, Northern State Parkway, Southern State Parkway, state Route 135/Seaford Oyster Bay Expressway, Sagtikos/Sunken Meadow Parkway and Robert Moses Parkway.
