Tappan Zee Bridge Dismantling
TZC is scheduled to continue removing large steel truss sections of the old bridge next week with the assistance of the project’s largest crane, dubbed I Lift NY. The truss sections, weighing up to 1,300 tons, will be placed on barges and transported to ancillary project facilities.

TZC is also completing the facility’s stair towers, exterior wall panels and rooftop.
Additional work includes:
- Excavation, backfilling and concrete pouring near Rockland and Westchester landings
- Expansion joint installation
- Removing temporary access structures
- Internal tower work

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.
