Beginning on Monday motorists should expect lane closures for concrete pavement repairs of State Route 231/Deer Park Avenue in the towns of Huntington and Babylon in Suffolk County.

A travel advisory issued by the state Department of Transportation said that starting on Monday between the hours of 10 a.m. and 3 p.m. there will be short-term lane closures on State Route 231 between the Southern State Parkway and the Long Island Expressway.

Portable variable message signs have been placed along the 4 1⁄2 -mile route with additional information about the closures.

According to the travel advisory, the closures are part of a $6.4 million DOT project to maintain the roadway that is expected to be completed in the winter of 2018-19. Work will be completed during off-peak hours.

Motorists are asked to drive carefully through the work zone, obey speed restrictions and follow the instructions of the flag persons — for motorists’ safety and the safety of the highway work crew.
