RCMP in northern Alberta had to shut down a highway in the area, after a sinkhole was discovered near the roadway.

Desmarais RCMP said on Monday at about 7 a.m., officers were alerted to the emerging sinkhole near Highway 754.

Officers responding to the call found the sinkhole near kilometre 74 on Highway 754 – and traffic on the roadway was reduced to one lane, as the sinkhole had started to spread underneath the northbound lane of the highway Monday morning.

Later that day, RCMP said the entire roadway had been closed, as the sinkhole had continued to expand the width of the highway.
