Tappan Zee Constructors, LLC (TZC) resumed marine operations and pile driving this week as icy conditions cleared in the Hudson River and crews could safely go back to work. Pile driving operations will continue next week and a second shift of workers will be onsite to resume welding on the piles that will become the permanent foundation for the New NY Bridge.
Pile driving will take place between 7 a.m. and 7 p.m. on weekdays, and occasionally between noon and 7 p.m. on Saturdays.
Beginning the week of Feb. 24, crews will conduct nighttime geotechnical investigations on the Westchester approach to the existing bridge, in the vicinity of the toll plaza. Lane closures to support these operations will be in place from 8 p.m. to 5 a.m., as needed, to minimize disruptions to traffic. This geotechnical investigation will confirm the soil conditions and ultimately allow the team to further streamline the design of the Westchester landings.
Lane Closures for New York State Thruway (I-87/I-287):
| Monday | Feb. 24 | Southbound, Right Lane Near Toll Plaza | 8 p.m. | to | 5 a.m. |
| Tuesday | Feb. 25 | Southbound, Right Lane Near Toll Plaza | 8 p.m. | to | 5 a.m. |
| Wednesday | Feb. 26 | Southbound, Right Lane Near Toll Plaza | 8 p.m. | to | 5 a.m. |
| Thursday | Feb. 27 | Northbound, Right Lane Near Toll Plaza | 8 p.m. | to | 5 a.m. |
| Friday | Feb. 28 | Northbound, Right Lane Near Toll Plaza | 8 p.m. | to | 5 a.m. |
Mariners should be aware that TZC will continue installing permanent piles in the vicinity of the side channels under the existing bridge, weather permitting. New temporary navigational lights have been installed to further define the 600-foot navigation channel under the main span. Both temporary and permanent piles are illuminated at night.
The U.S. Coast Guard has issued a revised Notice to Mariners with updated safety information, including the establishment of a Regulated Navigation Area (RNA) – 300 yards north and 200 yards south of the existing Tappan Zee Bridge. The U.S. Army Corps of Engineers has issued a modified permit for additional temporary mooring locations during construction of the new bridge. All boaters are advised to use the main channel, reduce wake and use extreme caution while transiting the area. If necessary, the Coast Guard may temporarily prohibit all vessel traffic in the RNA for safety purposes. The Coast Guard boating safety information and the modified mooring permit map can be found on the project website at NewNYBridge.com under the “Boater Safety” icon.
