13 November 2026 regional construction briefing. NYSDOT advises motorists of upcoming overnight closures of an I-84 to I-684 ramp in Putnam County for bridge demolition.
United StatesClosure notice dated 13 November
The New York State Department of Transportation issued a traveller advisory on 13 November 2026 for the westbound Interstate 84 ramp to Exit 68, connecting with southbound Interstate 684 in the Town of Southeast, Putnam County. The ramp is expected to close at night to facilitate bridge demolition.
Planned work window
NYSDOT gives a 10 pm to 5 am overnight window, commencing Monday night 16 November through Saturday morning 21 November, subject to weather. Signed detours are to be followed. This is a notice of anticipated restrictions, not confirmation that the bridge demolition is complete.
Construction engineering considerations
Bridge removal while roads remain operational nearby demands a staged demolition design, clear exclusion zones, independent checking of temporary stability, and monitoring of the underlying carriageway. The contractor’s demolition sequence must distinguish between primary support members, secondary bracing and components that can be lifted safely. Nothing in the public travel notice specifies the engineering method chosen for this project.
Work-zone reliability
A safe road reopening requires a formal release process covering residual debris, traffic barriers, signage, pavement condition and inspection of affected structures.
