The Twin Bridges on the Adirondack Northway (Interstate 87).

HALFMOON, N.Y. — The New York State Department of Transportation is advising motorists to expect overnight lane closures on the Adirondack Northway’s (Interstate 87) Twin Bridges over the Mohawk River between Albany and Saratoga counties starting April 15.

The work is in preparation for a project to paint the lower portions of the bridge’s arches.

The maintenance painting on what is formally known as the Thaddeus Kosciuszko Bridge will require that travel lanes be shifted slightly and be narrowed by one foot each and that temporary concrete barriers be installed at the bridge’s shoulders for the protection of workers. 

Once individual work zones are established three lanes of traffic are planned to be maintained at all times during the painting, which will occur during daytime hours behind the temporary barriers. DOT’s contractor will paint the lower portion of the arches up to approximately 10 feet above each of the bridge’s four shoulders (two in each direction).

That work is scheduled to continue until June 30 when it will pause until after Labor Day. At that point it will start again and continue until approximately Nov. 30.

Painting is planned to occur underneath the bridge during the summer months with minimal impacts to Northway traffic.

Also during the summer, the contractor will diamond grind the riding surface of the bridges. This work will require overnight and early morning lane closures. The dates for this work will be announced as the start time for this work segment draws closer.

Motorists are reminded to move over a lane as per the state’s Move Over Law, if safely possible or slow down significantly whenever encountering roadside vehicles displaying red, white, blue, amber or green lights. The Move Over Law’s stipulations include maintenance and construction vehicles in work zones. 

Motorists are urged to slow down and drive responsibly in work zones as fines are doubled for speeding in a work zone. Convictions of two or more speeding violations in a work zone could result in the suspension of an individual’s driver license.
