NEWARK - The state Department of Transportation is reminding motorists that the Route 1 & 9 Pulaski Skyway is closed this weekend.

The closure will run from 9 p.m. Friday until 5 a.m. Monday. A new floor beam supporting the travel lanes over Tonnelle Circle in Jersey City will be installed. All traffic on Route 1 & 9 will be detoured.

The northbound highway will be closed at the Skyway entrance near Newark Liberty International Airport. Southbound 1 & 9 will be closed from Route 139 West to Tonnelle Circle.

Additionally, a series of lane and ramp closures in and around the Tonnelle Circle area will continue during overnight hours and on weekends through the end of August.

The work is part of a $1 billion project to rehabilitate the Pulaski Skyway that officials say will extend the life of the Skyway by 75 years.
