OBBINSDALE, Minn. – Robbinsdale emergency responders have closed sections of roads near 42nd Avenue and Highway 81 due to a sinkhole and a water main break.

Authorities said the hole, which is estimated at about 60 feet in diameter and 20 feet deep was first noticed at about 10 a.m. on Saturday.

An officer was monitoring the high water in the area due to the water main break when he noticed that water was pouring into a hole in the middle of the roadway.

“This is unbelievable,” said Robbinsdale Mayor Regan Murphy. “First, all of the water and then when the water cleared, we realized we had a huge hole in the middle of one of main intersections.”

Officials said the water main break was not caused by the storms. It was just bad timing that cause a joint in the main to break.

“A 36-inch pipe with a failed joint at 80 pounds of pressure,” said Tom Mathisen. “It doesn’t take much to blow up a road.”

The pipe was put in place in 1963.

Authorities said the cities impacted by the water main break include New Hope and Crystal.

The intersection is expected to remain closed for two to three weeks.

When the water receded, the sinkhole was quite visible.

A nearby park was also under water as a result of the flooding.
