An early morning water main break seriously impacted the early morning commute for Calgarians on Thursday and caused a massive sinkhole to open up on McKnight Blvd.
The sinkhole appear in the two westbound lanes of McKnight Blvd. and 2 St. NW at around 6 a.m. and shut down traffic to only one lane.
City crews are on site repairing the broken main and expect the repairs to be finished on Saturday, July 9.
The roadway should reopen on Sunday.
The City wants to remind drivers to use caution when in any construction zone and thanks them for their patience in dealing with this problem.
