A stretch of Blair Road near the Pine View Golf Course reopened Sunday after a large hole formed the day before in the side of the east Ottawa thoroughfare.
A temporary fix has allowed the road to reopen, said Alain Gonthier, the City of Ottawa's director of infrastructure services.
Gonthier told CBC News on Saturday that a broken watermain underneath a culvert had caused significant erosion, which led to the collapse.
The watermain, whch was first installed in the 1970s, still has to be replaced, Gonthier said in an update Sunday.http://www.cbc.ca/news/canada/ottawa/sinkhole-blair-road-police-1.4441430
