Northbound traffic lanes of the New York State Thruway (I-87/I-287) in Westchester County will continue to be shifted near the approach to the Tappan Zee Bridge to provide room for construction of the New NY Bridge landing. Weather permitting, the operation will be completed during the coming week. The four relocated northbound lanes will be about six inches narrower than existing lanes and will have a reduced speed limit of 45 mph.
Tappan Zee Constructors, LLC (TZC) will be conducting the nighttime and overnight road work as follows:
The New York State Thruway (I-87/I-287) southbound across the Tappan Zee Bridge and the Tarrytown toll plaza will be reduced to two lanes from 10 p.m. to 11:59 p.m. on Friday, Oct. 3. Traffic on this stretch will be reduced to one lane between midnight and 6 a.m. on Saturday, Oct. 4. Both 35-mph E-ZPass lanes also will be closed during this time.
The New York State Thruway (I-87/I-287) northbound between exit 9 and the Tappan Zee Bridge will be reduced to two lanes from 9 p.m. to 11:59 p.m. on Saturday, Oct. 4. Traffic on this stretch will be reduced to one lane between midnight and 7 a.m. on Sunday, Oct. 5.
The New York State Thruway (I-87/I-287) southbound across Tappan Zee Bridge and the Tarrytown toll plaza will be reduced to two lanes from 10 p.m. on Saturday, Oct. 4 to 8 a.m. on Sunday, Oct. 5.
The New York State Thruway (I-87/I-287) northbound between exit 8A (Route 119) and the Tappan Zee Bridge will experience lane closures at regular intervals to install temporary barriers and fencing from Monday, Oct. 6 to Wednesday, Oct. 8. On these dates, the Thruway will first be reduced to three lanes from 7 p.m. to 8 p.m., then to two lanes from 8 p.m. to 5 a.m. the following morning and expanded to three open lanes once again from 5 a.m. to 6 a.m.
Construction will continue in the Hudson River as crews place the foundation for the New NY Bridge. Work will include pile driving between 7 a.m. and 7 p.m., Monday through Friday and noon to 7 p.m., Saturday.
A second shift of workers also will continue pile welding, pile cleanout and concrete placement operations associated with permanent foundations.
TZC will continue construction on the new bridge’s Westchester landing, drilling holes into the bedrock for the foundation. The drilling process produces less noise than the impact pile driving alternative, and TZC has implemented noise-reducing measures to further minimize noise levels during the eight-week operation, which is anticipated to conclude in November.
Work will continue on the Rockland work trestle near the shoreline, including pile driving and cofferdam installation. The trestle will support equipment used for the construction of the westernmost section of the new bridge.
The U.S. Coast Guard has established a Safety Zone surrounding 16 construction barge mooring locations at the project site. No unauthorized vessels are allowed in the Safety Zone. In addition, marine law enforcement will be enforcing the rules of the expanded Regulated Navigation Areas (RNAs) east and west of the Safety Zone. The RNAs stretch 500 yards north and 500 yards south of the existing bridge. Boaters are urged to transit the main channel with no wake at a maximum speed of 5 knots, and to use extreme caution on the river at all times.
More New NY Bridge boater safety information, including the U.S. Coast Guard Notice to Mariners and construction site maps, can be found here atNewNYBridge.com. An interactive map showing vessel locations on the Hudson River is also available here for recreational and commercial boaters to get updated information on this very active construction zone. The GPS tracking map is for informational purposes and not intended for navigation.
Mariners also should be aware that TZC will continue work in the vicinity of the side channels under the existing bridge. Additional temporary navigational lights have been installed to further define the 600-foot navigation channel under the main span. Permanent elements of the new bridge are lit per U.S. Coast Guard requirements, as are all moorings, barges and other equipment.
