TARRYTOWN, N.Y.-- Work began this week on the Rockland trestle, which is the second temporary work platform to be constructed as part of the Tappan Zee Bridge replacement project.
The work includes daytime pile driving to install the temporary foundation piles needed to support the platform. Pile driving will be limited to 7 a.m. to 7 p.m. on weekdays and, occasionally, on Saturdays from 12 p.m. to 7 p.m.
In addition, dredging crews will work around the clock starting from the main navigation channel end of the dredging footprint towards the shoreline on both the Rockland and Westchester county sides of the bridge. Dredging is expected to continue until Oct. 31.
The operations will deepen the river's shallow water level in the work zone by removing sediment from the river bottom.
