I-87/I-287 Southbound Fully Closing in Rockland County Early Saturday, Sept. 9

The New York State Thruway Authority announced Friday that all southbound lanes south of Exit 12 in West Nyack will be closed early Saturday to remove a badly damaged portion of the South Broadway overpass that was damaged by a tractor trailer on August 31.

Southbound lanes south of exit 12 To Exit 9 will close at 12:01 AM Saturday in addition to the Tappan Zee Bridge until likely Saturday evening. All motorists should avoid the area beginning Friday evening and take alternate routes.

The overpass is currently closed to vehicle traffic. Following multiple inspections this week, Thruway and consulting engineers determined that two damaged girders should be removed, and other work completed to stabilize the overpass.

All southbound lanes south of exit 12 (West Nyack – NY Route 303 – Palisades Center Drive) and over the Tappan Zee Bridge will be closed after 12:01 a.m. Saturday, Sept. 9, and are not expected to fully reopen until later that afternoon or early evening depending on the operation.

Motorists are strongly advised to avoid the area beginning Friday night and take alternate routes on Saturday.

Here’s what the New York State Thruway Authority reports motorists and residents should expect starting Friday night:

• At 8 p.m. Friday, one southbound lane near exit 10 (Nyack – South Nyack – US Route 9W) will be closed, leaving three travel lanes.
• At 11 p.m. Friday, three southbound lanes near exit 10 will be closed, leaving only one travel lane open. Traffic delays will be significant.
• After 11 p.m. Friday, the entrance ramps to the southbound Thruway at exits 10, 11 (Nyack), 12 and 13 (Palisades Interstate Parkway) will begin to close.
• After 12:01 a.m. Saturday, all southbound lanes will be closed and all traffic will be diverted to exit 12 in West Nyack.
• All day Saturday – work will continue on the overpass and highway below followed by the cleanup.
• Travel lanes will open as soon as safely possible.
• Travel lanes in the northbound direction will remain open throughout the work; the northbound left lane near the work zone will be closed.
• The Authority is working with state, county and local authorities on this operation, which will take place rain or shine.
