Water flowed through a portion of downtown St. John's Monday morning, gushing from a crack in the pavement of King's Road by Bond Street and closing down the intersection to traffic.
The water buckled the pavement by the intersection, creating a hole that spanned both lanes of the street and pushing rocks and chunks of asphalt downhill.
One worker on the scene said he believed it to be a 16-inch water main that cracked.
The Royal Newfoundland Constabulary were on scene before 9:00 a.m. and closed a portion of King's Road near Bishop Feild Elementary, with officers directing traffic away from the area.
Because of the crack, the city said water will be shut off from 12:30 p.m. to Midnight in sections of Downtown St. John's. Roads from Duckworth Street to Queens Road will also close during the same time period.
Drivers are asked to take an alternate route to expect delays. The city aims to have work completed by Midnight tonight.
