Nighttime electrical work on the Tappan Zee Bridge will commence on Tuesday July 15 from 9 p.m. to 6 a.m. The bridge will remain open to traffic as the nighttime operations continue throughout the week. However, the work will require the closure of two northbound lanes across the bridge during those hours. In addition, on Friday July 18, the exit 10 (South Nyack) southbound entrance to New York State Thruway (I-87/I-287) will be closed from 8 p.m. to 6 a.m. Motorists will be directed to exit 11 (Nyack), located off Route 59 in Nyack.
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 five 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 at NewNYBridge.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 illuminated at night as are all moorings, barges and other equipment.
TZC will continue work on the Rockland County landing of the new bridge. The work will last several weeks and include the installation of sheet piles, some measuring over 50 feet long. These interlocking steel sheets will support the existing roadway during the excavation and construction process. A large crane with a vibratory pile hammer will install the sheets, and be positioned behind a temporary concrete barrier in South Nyack.
Construction will continue in the Hudson River as crews continue the installation of the foundations for the New NY Bridge. Work will include pile driving between 7 a.m. and 7 p.m., Monday through Friday and 12 noon to 7 p.m. on Saturday.
A second shift of workers will also continue pile welding operations associated with permanent foundations.
Work will also continue on the Rockland temporary work trestle near the county shorelines, including pile driving to install the temporary foundations needed to support the platform. The trestles will support cranes for the construction of the western-most section of the new bridge.
