DURHAM — It could be several days before a sinkhole on Hwy. 401 is fixed.
The hole is in the far left eastbound lane between Brock Street and Thickson Road in Whitby.
According to the Ministry of Transportation (MTO), the “formation of the sinkhole is related to Durham Region’s ongoing watermain installation near Brock Street, which includes tunnelling under Highway 401.”
Susan Siopis, the works commissioner for the Region, said, “A contractor working on behalf of the Region is currently engaged in constructing a new water-main, by means of micro-tunnelling, extending from the intersection of Victoria Street and South Blair Street crossing under Highway 401 to east of Champlain Court in the Town of Whitby.
“During the course of tunnelling, there was some settlement observed last week on Highway 401 requiring lane closures in the eastbound direction. The settlement was addressed the same day,” Siopis added.
The hole was found last week and MTO “maintenance staff performed emergency repairs to stabilize the road bed immediately. As a precaution, the lane remains closed. We hope to reopen the lane as soon as possible.”
The MTO and the Region are looking “to come up with a solution that would allow tunnelling to continue without further impacting the highway.”
Siopis noted, “We expect the lane to be paved this weekend and reopened for next week.”
The left eastbound lane has been closed since the hole was discovered and the closure is causing traffic chaos during the Christmas season.
