The sinkhole problem on Interstate 80 in Wharton continues to escalate as 135 suspected voids have now been identified under the eastbound lanes near Exit 34. Initially, 90 voids were discovered, but further investigation by the New Jersey Department of Transportation (NJDOT) revealed more potential hazards. On February 10, a depression in the highway transformed into a massive sinkhole, marking the second such incident in less than six weeks.
The NJDOT has been conducting advanced scanning and testing, along with proactive drilling and grouting operations, to stabilize the roadway. As of now, 51 locations have been drilled, and 36 have been filled with grout. Despite these efforts, the repairs are expected to be extensive and time-consuming, with no clear completion date.
Transportation Commissioner Fran O'Connor emphasized the importance of designing a repair that ensures the long-term integrity and safety of the roadway. "It is important that we act now to make lasting repairs, so we don't have to come back any time soon," O'Connor stated.
The voids are believed to be linked to abandoned mines in the area, including the Huff Mine and Johnson Hill Mine, which have been dormant since the late 1860s. State Senator Anthony M. Bucco acknowledged the frustration faced by commuters, residents, and businesses and assured that NJDOT crews are working diligently to resolve the issue.
Eastbound traffic on I-80 remains detoured, with drivers being redirected to Routes 46 and 10. The NJDOT continues to prioritize safety as they work to reopen the interstate as soon as possible.
