Westbound Highway 212 in Cologne reopened Sunday afternoon.
“MnDOT crews worked on the repairs on Friday and Saturday. Despite the rain, they were able to reopen it early on Sunday afternoon,” according to a Carver County press release.
On the morning of July 17, crews discovered that an 18-inch culvert collapsed under the two westbound lanes and acceleration lane from County Road 36, according to Bill Augello, Minnesota Department of Transportation drainage superintendent.
With nowhere to go, water continued to drain from the median around the pipe, ultimately creating a five-feet-wide void, Augello said. After the damage was spotted, the road was closed the afternoon of July 17 and traffic detoured.
“We decided to close the road down for the safety of the motoring public,” Augello said.
“The main failure happened because of the recent rains, Monday night into Tuesday,” Augello said. “It’s been a busy year for us, for sure, with the heavy rains.”
On Friday and Saturday, the culvert was capped off and filled with concrete. Then crews filled the void with concrete.
The road surface itself was in good shape, Augello said.
A 36-inch culvert at a lower point in the median will handle drainage, Augello said. “We have some plans further down the line to do some upgrades on that 36-inch to make it able to take more water.
