A repaving project partially closes a 1.3-mile stretch of Route 25A in Wading River and Ridge starting Monday — mostly during the overnight hours, the state Department of Transportation said.

The stretch between Wading River Manor Road in Wading River and the William Floyd Parkway in Ridge is scheduled for repaving from 10 p.m. to 6 a.m. Monday through Friday, the agency said.

Weather permitting, the project is expected to be completed in about three weeks.

Travel lanes will be shifted or closed when needed, according to a news release. Single lanes in each direction are expected to remain open.

An alternating one-way traffic pattern will be utilized when lanes are too narrow for travel in both directions. Brief closures of all lanes are possible when construction equipment is being moved.

Construction is predominantly overnight, but occasional off-peak, midday lane shifts or closures are likely between 10 a.m. and 3 p.m.

The repaving is part of a $13.9 million state project for repairs to roads damaged during the winter months because of high traffic and harsh weather conditions, the agency said.

Motorists should use alternate routes, but if they have to use the roadway during construction they should drive carefully through the work zone, the agency said.
