Getting closer: the first span of the new bridge is set to open in one year and (number of) months? In the first press release of 2015: construction crews will begin assembling the formwork — steel, earth and concrete — for the new bridge’s abutment on the Rockland shoreline.

Limited concrete placement continues after the mid-December accident involving one floating concrete batch plant that resulted in the bridge builder shutting down both batch plants while it assesses the situation.

Concrete for foundations near Rockland’s South Nyack shorelines will be from local concrete suppliers via trucks. Tappan Zee Constructors, LLC (TZC) will use the Thruway southbound access ramp to the Rockland trestle, exiting to the Thruway via the northbound access ramp.

“People on River Road will not notice a difference,” TZC spokeswoman Carla Julian assured. “It’s always been planned that the land work will have concrete trucks for the abutment. We redesigned the road for longer acceleration.”

And pile driving for the new foundations is from 7 a.m. to 7 p.m. on weekdays; occasionally, from 12 noon to 7 p.m. on Saturdays. Also ongoing are pile welding, pile cleanout and concrete placement operations.

Each truck holds about 10 cubic yards of cement, she said, and pours are not more than 200 cubic yard. The bridge builder is working to get the batch plants online, realizing the time restrictions regarding the cement pours. There will be two or three trucks of curing concrete on the access road since trucks have to be placed before it concrete cures.

Curing is a process that protects concrete from losing moisture and within a reasonable temperature range.
