Some good news for drivers on Highway 400 after an 11-foot-deep sinkhole led to road closures and traffic delays near Bradford West Gwillimbury since Monday.
In an update on Thursday, Ontario Provincial Police said repairs to the sinkhole have been completed, and all affected southbound and northbound lanes of the highway at Line 5 have reopened to motorists.
The left southbound lane was shut down in the area since Monday, when the sinkhole opened up along the median strip. OPP Sgt. Kerry Schmidt said the sinkhole was located in the left southbound lane approaching Line 5.
The closure was then expanded on Tuesday to include the left northbound lane of the highway.
On Wednesday, Sgt. Schmidt shared a new video on social media showing crews tending to the sinkhole, noting that repairs are ongoing.
“The hole itself is relatively small, but underneath that hole, there is a significant cavity,” Sgt. Schmidt said.
“[Crews] are going to try and get asphalt pulled away so they can get a better look inside to see what they’re dealing with. They’re estimating between 20 to 30 yards of concrete are going to have to go in there to fill this hole.”
