Bus gets stuck in sinkhole on flooded Colorado road

A bus fell into a sinkhole as it was driven through a flooded road in Clorado, police say.

The vehicle became trapped at it was making its way through Boulder, Colorado, near Denver, according to authorities.

Police say the incident took place at around 4.30pm on Wednesday and forced them to close westbound Arapahoe at 55th Street in the university town.

All of the passengers on the bus were evacuated and no injuries were reported.

Police tweeted that the bus, which was in the middle of the road, was “actively sinking.”

The Regional Transit District said a fire hydrant had been pouring water into the road and the driver could not tell there was damage and drove through it.

It is not known yet what caused the sinkhole and police have not said how long the road will be closed, according to FOX31.

The bus was eventually pulled out of the sinkhole, with water service in the area impacted for hours.

“Sinkholes are depressions in the ground surface. They are caused when voids in the subsurface get large enough that the overlying material can no longer support its own weight and collapses into the void,” states the Colorado Department of Transportation.

“The void can be caused by groundwater dissolving and removing material, erosion around drainage features, and (most frequently in Colorado) mining operations. The Geohazard Program performs emergency investigations when sinkholes begin to develop to determine the size and extent of the sinkhole.”
