This huge sinkhole near the entrance to Roosevelt Park Zoo opened early Friday afternoon and nearly swallowed a large trailer carrying flood debris. The hole is 15 to 20 feet long, 8 to 10 feet wide and at least 8 feet deep.

Minot Public Works Director Alan Walter said the sinkhole was caused by a sewer collapse. Sinkholes have been common throughout the city as high groundwater has caused a large amount of subsurface erosion. East Burdick Expressway will be closed from the west end of the Burdick viaduct to Eighth Avenue Southeast until further notice.

Detours will be from Fifth Street Southeast to Valley Street and from Valley Street to Eighth Avenue Southeast.
