A large sinkhole caused by recent heavy rain has forced the evacuation of a Janesville apartment building.
City Public Works Director Jack Messer says the hole developed in an area that used to be an old quarry filled with sand and gravel.
Erosion has widened the hole and it's now within fifteen feet of the building. There's also a sixty foot drop off.
Messer said they felt it was better people evacuate until experts can come in and determine how to stop the erosion.
