Some lanes of Sunrise Highway within Babylon Town will be closed during off-peak travel times during the next several months to allow for guide-rail repairs and other improvements, the state Department of Transportation said in an advisory.

The left lanes in both eastbound and westbound directions will be closed from 10 a.m. to 3 p.m., Monday through Friday, from Albany Avenue, east of Route 110 in Copiague, to Forsythe Avenue, west of Route 109 in Lindenhurst, the DOT said.

At least two travel lanes in each direction will remain open during the construction, which is expected to last until the fall, the advisory states.

The work, which includes the installation of a chain-link fence in the median area to encourage pedestrians to cross at designated crosswalks, is weather-dependent and may be postponed, canceled or prolonged because of inclement weather, the DOT said.

It is part of a $3.8 million DOT project to install pedestrian safety improvements on Sunrise Highway from the Nassau-Queens border to North Niagara Avenue.

Notices will be placed on electronic road signs but motorists are advised to plan alternative routes to avoid possible delays, the DOT said.
