Video shows the new 15 X 15 hole, the first on the west side of Route 80, is nearly opposite the area on the east side where two sinkholes opened earlier.
Officials say a NJ man built a library of information for terrorists that included details about making suicide vests, detonators and timers, and improvised bombs.
A total of 135 locations around Route 80 in Wharton, mostly abandoned mine shafts, have been identified by DOT engineers for closer assessment and mitigation.
The eastbound lanes of Route 80 are expected to remain closed for at least another three weeks to get to the root cause of two sinkholes that have opened up in the past two months.
