Thruway/Bridge Work, Closures in South Nyack, Tarrytown This Week

Here’s this week’s work schedule for the New NY Bridge:

TARRYTOWN: Two lanes of the southbound New York State Thruway in Tarrytown will be closed between 7 p.m. and 6 a.m. during every overnight this week (Monday evening, Mar. 9 through Saturday morning, Mar. 14).

The one-mile closures from the toll plaza to just north of exit 8A (Elmsford – NY Route 119 – Saw Mill River Parkway North) are necessary to perform work on an electronic highway sign structure. Two lanes of the southbound Thruway will remain open during the closures.

SOUTH NYACK: The exit 10 on-ramp to the southbound Thruway in South Nyack will be closed from 9 p.m., Tuesday, Mar. 10 to 5 a.m., Wednesday, Mar. 11.

The closure will allow Tappan Zee Constructors, LLC (TZC) to continue restriping the roadway and moving temporary barriers. Drivers will be directed to use the entrance ramp located on Route 59 in Nyack.

Starting the week of Mar. 9 and continuing for approximately two weeks, TZC will construct the South Nyack abutment foundations. Located near the Thruway’s northbound access ramp in Rockland County, the operation will include the installation of sheet piles to support the exiting roadway. TZC will install the sheet piles during daytime work hours and will utilize noise attenuation techniques to minimize impacts to residents.

The abutments, which will be made of steel and concrete, will serve as strong bases where the new crossing meets the landside roadway.

GENERAL: Crews also will continue working on the bridge’s landings on the Rockland and Westchester shorelines.

Ice buildup on the Hudson River will continue to limit operations at the project site during the week of Mar. 9. TZC has included a two-month winter shutdown in its schedule to account for winter weather conditions.

TZC’s inclement weather preparation protocols include having tug boats on the water at all times, inspecting and adjusting all mooring lines, inspecting crane barges and securing all equipment, moving the large majority of cranes to shallow water moorings and taking all smaller crew boats out of the water. Additionally throughout every storm, TZC uses video and GPS to monitor the entire fleet of project vessels from its security operations center.
