Construction of the Rockland Bulkhead will begin next week as crews enlarge the work platform in the New York State Thruway Authority’s Rockland maintenance area located on River Road in South Nyack.
The bulkhead will be part of the Thruway’s permanent dock and serve as the access point for Tappan Zee Constructors, LLC’s (TZC) Rockland trestle. The trestle is the support platform that will allow TZC to build the foundations for the new bridge near the Rockland shoreline without dredging in that area. TZC will utilize the bulkhead for support of construction throughout the entire project.
Orange and Rockland Utilities will install new utility poles near River Road in South Nyack to support utility relocations which are needed for the New NY Bridge project. These operations may require temporary lane closures and will be performed by the utility.
Test pile driving operations will be conducted over the next three months at proposed locations for pile foundations. The test pile program will verify subsurface conditions in preparation for the construction of the bridge’s permanent foundation.
Multiple crews will conduct night time boring operations along I-87/I-287 in both directions in Westchester and Rockland Counties. The night time operations are necessary due to lane closure restrictions during day time hours that are in place to keep traffic flowing over the current bridge. Boring operations began at exit 10 in Rockland County and continue to move west into Westchester County and then back to Rockland for one final boring location.
Ongoing operations
- Temporary Westchester trestle construction including pile driving on weekdays from 7 a.m. to 7 p.m.
- Survey inspections on existing bridge

- eotechnical land borings
- Mobilization at the exit 10 staging area
- Support for river-based work from the Rockland shoreline
- Extension of Thruway’s Rockland maintenance dock
