The current severe sinkhole closure on northbound I-684 started on Tuesday, after a barrage of powerful thunderstorms, flash flooding, and even a tornado watch swept across Westchester County.

The underlying issue actually began nearly two weeks prior. On July 9, 2026, a New York State Department of Transportation contractor performing routine maintenance discovered a "developing roadway depression" caused by a deteriorated drainage pipe.

This week, the left and center lanes were blocked on northbound Interstate 684 just north of Exit 6A (NY 22 to NY 138/Goldens Bridge) due to emergency sinkhole repairs.

Commuters experienced severe delays, for several miles.

"Crews are repairing a deteriorated drainage pipe on I-684 between Exits 6 & 7," New York State Police warned Wednesday morning. "Traffic is reduced to ONE lane northbound. Expect significant delays. Use alternate routes if possible and use caution in the area."

Drivers Told To Use Other Routes

Because of the heavy traffic near the Exit 6A ramp connection, the New York State Police and NYSDOT strongly urge drivers to bypass the area entirely.

Other routes include the Taconic State Parkway or local roads like Route 22 and Route 100.

Emergency crews have been on site since the storm cleared to to excavate, stabilize, and rebuild the roadway.

Drivers tell Hudson Valley Post traffic is moving smoothly as of 7:30 a.m. on Thursday.
