A large sinkhole that resembles something out of a Hollywood movie has closed a section of Bayview Avenue to traffic.

It happened overnight on Thursday after a water main break. Bayview Avenue just north of Steeles Avenue is closed between Proctor Avenue and Laureleaf Road as crews work to fix the buckled pavement.

In some sections, the crack is as wide as a traffic lane.

CBC’s Lorenda Reddekopp was at the scene and said York Regional police officers were describing the nine-metre deep sinkhole as "something out of Jurassic Park."

"You just do not expect to see a huge crack down the middle of the road and then the road just buckled in at the middle," Reddekopp reported.

"Crews are starting to dig but this is not an easy problem to fix. It’s going to take days, maybe even weeks."

Police say people will need to find another route not just for today, but for the days ahead.
