A large sinkhole closed a major St. Paul intersection on Saturday.
A sewer line collapse below the intersection of Phalen Boulevard and Johnson Parkway on Friday morning has caused the ground to sink, officials said. The sinkhole is an estimated 25 feet across and 25 feet deep.
The sinkhole started about an hour later. St. Paul police first spotted the problem.
No one was hurt during the collapse. The sewer line is operated by Metropolitan Council Environmental Services.
A spokesman for Metropolitan Council Environmental Services says it's too soon to tell what exactly caused the sinkhole but says it was likely natural corrosion of the concrete sewer.
Crews said they will reopen the parkway by next Friday.
The city is using alternate above-ground pipes to bypass the sewer system failure.
