A one-block portion of Jeanne-Mance St. is closed between De La Gauchetière St. and René-Lévesque Blvd., after the street partially opened up.
The sinkhole measures roughly four feet by two feet. It's not clear exactly how long the closure will last.
The Ville-Marie borough says people can still use the sidewalks, but motorists can't use the street, except for those who've parked their cars at the Guy Favreau Complex. They can use the street — but will have to turn south.
