TZC Continues Using Local Supplier Concrete; Overnight Lane Closures This Week for Repainting

Calendar-FlippingToday begins year three for Tappan Zee Constructors, LLC (TZC), which will have the first span of our new bridge ready for wheels by 2016. Next year.

Since last month’s batch plant accident, concrete for foundations near Rockland’s South Nyack shorelines is from local concrete suppliers. The project’s leading supplier of stone, Tilcon New York, temporarily ceased deliveries and removed its moored barges. There has been “no resumption of deliveries yet,” company spokesman Geoff Thompson said via email January 16.

Here it comes, Rockland:

Three northbound lanes on I-87/I-287 will close overnight January 20 while new lines are painted. Note: if you’re traveling near Exit 10 in South Nyack, then be aware two lanes will close at 8 p.m., a third will close at midnight, and all will reopen January 21 at 5 a.m.; single single file until then.


Project officials said the New York State Police will conduct several temporary traffic slowdowns so the work can be finished safely. So either don’t plan to be in a hurry during the wee morning hours or leave earlier to get where you’re going. The Exit 10 ramp in South Nyack January 20 will close at 10 p.m. and will reopen the next day at 5 a.m. Use Exit 11, then follow signs to Routes 9W and 59.

Westchester, you’re next:

Prepare to stop January 22 if you’re driving south at night on the Thruway near Exit 9. Two lanes will close at 8 p.m., a third will close at midnight, and all will reopen January 23 at 5 a.m.; until then, also single file.


If you’re coming across the bridge and plan to use Exit 9 (Tarrytown – Sleepy Hollow – Route 9) between January 22 at 10 p.m. and January 23 at 5 a.m., then you’re in for a detour. Take Exit 8A (I-87 – Elmsford – Route 119) and follow signs to Route 9.

Rain or snow means all bets are off.

Construction crews continue assembling the formwork for the new bridge’s abutment on the Rockland shoreline. 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.

Check out the Coast Guard’s weekly Local Notice to Mariners, excerpted and in its entirety, listed under Boater Safety Information on the New NY Bridge website. A LNM primer is here. Details about ongoing work are here.

Quiz: How many piles will be installed to support the new bridge? Hint: They’d stretch from Tarrytown to Highland, NY, or to Neptune Township, NJ. See here for the answer. Knew it? Good! You were paying attention.

I’d like to know what you think.
