A package containing stuffed animals and trash found on New Jersey's Interstate 287 caused hours-long delays and miles-long backups Monday morning as investigators brought in robots to assess any potential threat, authorities said.
The highway reopened shortly after 11 a.m. after earlier closures in both directions near Boonton because of the investigation.
At least three miles of the busy highway were shut down between Hanover and Parsippany as the bomb squad sent robots to check out the item.
Southbound traffic backed up all the way to Boonton and northbound traffic backed up to Morristown, authorities said.
Residual delays were expected and drivers were being advised to seek alternate routes.
