New Jersey transportation officials had concerns about Interstate 80 sinkholes as far back as 2009, when they conducted a construction project to reinforce an abandoned mine near a section of the highway that’s had sinkholes and other problems during the past two months.
The 2009 project was proposed to address sinkholes and collapses in the Huff Mine which a project description said was in the vicinity of Exit 34 in the Wharton area of Morris County.
A state Department of Transportation description said the project was to address cave-ins and other issues in the abandoned iron mine that is in the area of the most recent sinkholes on I-80 East.
