East Anchor Span Removal
TZC continues to remove material from the Hudson River following the controlled demolition of the old Tappan Zee Bridge’s east anchor span, weather permitting.

Bicycle/Pedestrian Path
TZC will continue to install rebar, pour concrete and strip forms on the northern side of the westbound span for the bridge’s shared-use bicycle/pedestrian path, barrier and overlooks.

At the Westchester Landing, foundation construction continues on the terminus site walls, the nearby storage building and canopy area. Operations include rebar installation, pouring concrete, backfilling, and conduit installation.

At the Rockland Landing, a section of the Esposito Trail from Clinton Avenue and South Franklin Street to South Nyack Village Hall remains closed for the construction of the side path. Pedestrians and cyclists are being detoured to South Broadway and through Elizabeth Place Park.

Crews will continue construction of a retaining wall along Hillside Avenue, necessitating temporary lane closures. Flag persons will keep traffic moving by alternating the directional flow between east and west. Crews also are constructing a highway noise barrier at Elizabeth Place Park.

Additional work includes:

  • Excavation, grading, pouring concrete, drainage work and installing barrier near bridge landings
  • Internal work and area grading at the Thruway Maintenance and New York State Police facilities
  • Dismantling of the old bridge’s foundations, weather permitting

Boater Safety
The western 300 feet of the 600-foot wide main navigation channel is closed to all vessel transits Monday through Saturday from 7 a.m. to 5 p.m.

Periodic partial closures of the main navigation channel are anticipated to continue during the demolition period, as TZC continues to dismantle the Tappan Zee Bridge’s west anchor span and salvage the collapsed east anchor span. Cranes, barges and other equipment will occupy parts of the channel during this time. Boaters are strongly encouraged to avoid the project site during the closures and to avoid the Regulated Navigation Areas, located east and west of the main channel.

Times and dates of the closures are subject to change and will appear in the U.S. Coast Guard’s weekly Notice to Mariners; on the project’s Twitter feed (@NewNYBridge); and broadcast on Marine Radio Channel 22A. Tappan Zee Constructors can be contacted via Marine Radio Channel 16 for assistance.

Rockland and Westchester marine units continue to patrol the project site.
