It's going to be a while yet before a part of Elgin Street in Sudbury is reopened to traffic.
The downtown street was closed between Cedar and Elm Streets Monday after a burst watermain created a large sink hole.
The city of Greater Sudbury had hoped to have the repair completed by noon on Tuesday, but workers still need to pour and smooth asphalt before traffic can be allowed through that section of roadway.
The hole is near the old Market Square, which is undergoing construction to be the new school of architecture.
Sudbury police were called to the scene around dawn on Monday morning.
Sergeant Corinne Fewster, who reported she could see running water within the hole, said she was able to prevent a van from falling into the cavern before the road was closed off.
"When I first arrived, the far right corner ... had not yet sunk in and I was stopping a van from going," she said.
"I was standing very close to that edge when the far right corner fell in."
