BOULDER, Colo. - A sinkhole opened up Thursday in the middle of the road near Folsom Field on the University of Colorado Boulder campus.
Folsom Street was closed between Taft Street and Colorado Avenue while City of Boulder crews repaired the sinkhole. Video from AIRTRACKER7 showed that the sinkhole was in the middle of both lanes and was initially the size of a car.
"I've never seen (a sinkhole) this big, not in the middle of a city," said Mike Keuter who works at CU.
Officials said a 16-inch water main broke under the road causing Folsom Street to collapse around 3:30 a.m.
Mike Banuelos with the city of Boulder said the main broke due to pipe erosion. He said a water main broke in the same area about a year ago.
Banuelos said the buildings on Folsom between Taft Drive and Colorado Avenue are currently without water, but that the University of Colorado was not affected.
Water service was restored to the area at approximately 7:50 p.m. The closure may be in place until Friday morning.
The sinkhole is along the Bolder Boulder route.
