Tappan Zee Constructors (TZC) is scheduled to raise and place overhead gantries over the New York State Thruway (I-87/I-287) near the bridge in Tarrytown and South Nyack next week. The work will necessitate multiple overnight lane closures and traffic stops, lasting between 20 and 40 minutes, in both directions during the overnights of Monday, April 22, Tuesday, April 23, and Wednesday, April 24.
Operations may be rescheduled to the overnights of Thursday, April 25, and Friday, April 26, in the event of inclement weather conditions.
Significant delays are expected, and motorists are strongly encouraged to avoid the area and take alternate routes on the nights of the operation.
