Tappan Zee Constructors, LLC (TZC) will be installing utilities to serve a temporary all-electronic tolling gantry in South Nyack near exit 10. The operation will involve phased construction and will require several nighttime and overnight lane and exit closings.
On Tuesday, Sept. 16, on the New York State Thruway (I-87/I-287) a single lane of the northbound exit 10 (South Nyack) off ramp will close from 9 p.m. to 4:30 a.m.
On Wednesday, Sept. 17, and Thursday, Sept. 18, the southbound entrance to the New York State Thruway (I-87/I-287) at exit 10 (South Nyack) will be closed from 9 p.m. to 4:30 a.m. Motorists are advised to follow the posted detour signs, which will direct them to Exit 11, located off Route 59 in Nyack.
On Friday, Sept. 19, on the New York State Thruway (I-87/I-287) a single lane of the northbound off ramp at exit 10 (South Nyack) will close from 9 p.m. to 4:30 a.m.
The steel frame gantry to support the all-electronic tolling equipment at the temporary location in South Nyack will be built next year, and will extend over the southbound lanes of the Thruway. All-electronic tolling technology for the Tappan Zee Bridge will be tested and implemented in 2016, for the duration of the New NY Bridge project.
Construction will also 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 will also continue pile welding, pile cleanout and concrete placement operations associated with permanent foundations.
TZC will also continue construction on the new bridge’s Westchester landing, drilling holes into the bedrock for the foundation. This drilling process will produce 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.
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 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.
