Large sinkhole shuts down highway in North Bay, Ontario

Staff writers
April 20, 2013 — A section of Highway 11 in North Bay, Ontario re-opened Saturday afternoon after a massive sinkhole opened up on the roadway.

A combination of high water levels and heavy rain caused a massive sinkhole to open up on Highway 11 North Bay, Ontario early Friday morning.

The Ontario Provincial Police reported the highway was reopened, in both directions, by around 5:30 p.m. on Saturday.

The Ministry of Transportation blamed the sinkhole on "a large culvert failure."

A second sinkhole was discovered on Highway 64, forcing a closure that lasted for several hours. The highway was re-opened by around 10 a.m.

The region was inundated with more than 30 mm of rain Thursday, prompting officials to close the Kinsmen and Kate Pace Way trail system following incidents of localized flooding. 

Ontario's Muskoka region has seen significant flooding as well.

On Friday, the communities of Huntsville and Bracebridge declared emergencies after more than 50 mm of rain overwhelmed waterways, leading to costly damages.
