The sinkhole that cratered a section of I-80 in New Jersey was caused by an abandoned mineshaft collapsing underneath the highway, state transportation officials say.

A sinkhole on a New Jersey interstate that's closed eastbound traffic for over 24 hours was caused by a collapse of abandoned mineshaft, officials said.

Construction crews are working around the clock to repair the ginormous hole along I-80 near Exit 40 in Wharton that caused massive traffic delays a day after Christmas.
