A stretch of eastbound Sunrise Highway in Nassau County will be partially closed at night for about six weeks because of a repaving project, the state Department of Transportation said.

Closures began Monday on a three-mile stretch from the Nassau-Queens border to Broadway in Lynbrook, the agency said.

Two lanes will be closed between 10 p.m. and 6 a.m. Monday through Friday for about six weeks, weather permitting. A single eastbound lane will remain open to motorists.

The repaving covers three miles of a deteriorated section of the road that is used by an average 50,000 vehicles a day, the agency said.

The top layer of the damaged pavement is being removed then replaced with new asphalt. After repaving, the project continues with traffic signal vehicle detector loops being replaced and fresh pavement markings.
