Sinkhole continues to close part of critical junction between I-287 and I-78



An exit at a critical junction between two major interstate highways remains closed due to a sinkhole reported early Sunday.

State Department of Transportation officials said emergency pothole repair at ramp I-287 north Exit 21A to I-78 east closed the ramp at Bedminster and traffic was diverted to the exit north of the site.

“NJDOT is still in the process of investigating the cause and identifying an appropriate fix,” NJDOT spokesperson Stephen Shapiro said Wednesday. “We are working on a solution to ease congestion in the stream area in the fastest way possible.”

He said officials hope to have more information next week. Engineers assess the situation and will design a repair.

Department of Transportation officials did not say the reason for the pit, which opened in the right lane and shoulder of the ramp, and which closed at 1:45 a.m. Sunday.

Officials said drivers have been warned to expect heavy traffic and delays until the ramp reopens and may want to consider taking an alternate route. Both Central Jersey commuters and interstate truck drivers rely on the interchange as a major intersection of north-south, east-west highways.

A recent $24 million project at the massive intersection of I-78 and 287 and 2020/206 Route in 2016 involved work to shift the ramp from I-287 North to I-78 East to South to make way for a new upper ramp and loop. This structure connected I-78 east to the I-287 north lanes on the right side of the highway.

Department of Transportation officials suggested drivers turn north by heading north on I-287 to Exit 26B of County Route 25 North/Mt Airy Road north to Bernardsville. Drivers must keep right ramp to I-287 South and take Exit 21A to I-78 East.
