An $8.4 million project that delivers new pavement markings to various state roadways on Long Island is underway, the state Department of Transportation said.

The pavement-marking work requires night and off-peak short-term lane closures on roadways throughout Nassau and Suffolk counties, the agency said in a Wednesday news release.

Overall, 27 locations on several roads will be re-striped "to assure proper visibility and maintain safe traffic movement and vehicle operation on Long Island," the release said.

New pavement markings will be provided on the following state roadways: the Sagtikos, Sunken Meadow, Bethpage, Ocean, Meadowbrook and Wantagh parkways, and on state roads 25, 25A, 25B/Hillside Avenue, 25C /Union Turnpike, 27, 27A, 102, 109, 110, 111, 112, 231 and 878/Nassau Expressway.

As with most roadwork projects, the operation is weather-dependent and may be canceled, postponed or prolonged due to inclement weather, the agency said.
