BOULDER, Colo. (KDVR) — A bus ended up in a sinkhole in east Boulder on Wednesday but no injuries were reported, the Boulder Police Department said.

Police shut down westbound Arapahoe Road at 55th Street after the bus landed in the sinkhole at Arapahoe Road and Commerce Street. All six passengers got off the bus safely but it continued to sink, police said.

The Regional Transit District said there was a fire hydrant gushing water and the driver thought it was just water, couldn’t tell the damage and drove through it.

Boulder Police said the sinkhole is growing and to avoid the area.

Westbound Arapahoe Avenue between Conestoga and Commerce streets will be closed at least through midnight. Water service in the area will also be affected for up to eight hours.
