Work Continues On Eastbound Span Roadway Preparation Underway

July 27, 2018

Tappan Zee Constructors (TZC) is scheduled to continue closure pours for the eastbound span’s base roadway, weather permitting. The work will allow TZC to install the structure’s traffic barriers and begin overnight deck paving next week. Construction vehicles will access the eastbound span from the southbound New York State Thruway (I-87/I-287) in Rockland County.

Tappan Zee Bridge Dismantling
TZC is scheduled to continue dismantling operations of the old bridge with the assistance of the project’s largest crane, dubbed I Lift NY. The machine will be used to remove pier caps next week, west of the Hudson River main navigation channel.

Concrete Pours at Rockland Landing
To complete the eastbound span’s mainline, TZC is scheduled to pour concrete at the Rockland landing next week, weather permitting. Concrete trucks are anticipated to access the area from the New York State Thruway or from the southbound maintenance ramp off River Road.

Roadway and Aesthetic Lighting
TZC is installing roadway lighting fixtures on the eastbound span. Periodic testing of the aesthetic lighting and roadway lighting is anticipated to occur in the coming weeks.  

Maintenance and State Police Facilities
TZC is scheduled to continue operations on the new State Police facility in Tarrytown, including wall framing, metal wall panel installation and pouring concrete. TZC will also continue internal work on the Thruway Authority’s new maintenance building in Tarrytown, which includes installing utility lines, windows and dry wall.

Additional work includes:

  • Formwork, subbase and barrier placement near the Westchester landing
  • Barrier and drainage placement near the Rockland landing
  • Expansion joint installation
  • Removing temporary access structures
  • Internal tower work
  • Electrical equipment installation and testing
  • Dismantling of the old bridge’s icebreakers, deck panels, piers and circular caissons

Boater Safety
Periodic closures of the main navigation channel are anticipated to occur during construction and demolition periods. 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.
