Crews have been working around the clock to fix the sinkhole, which opened suddenly at the Jeanne d'Arc Boulevard exit amid heavy rains in the region Sept. 4.
The Jeanne d’Arc off ramps are expected to remain closed until repairs are completed early this week, weather permitting, according to the city.
One eastbound lane was reopened during rush hours beginning on Sept. 12 to help ease traffic snarls caused by repairs.
The cost to fix the sinkhole is expected to be at least $5 million, up from the $1.5 million that council originally estimated it would take to fix the aging sewer.
A driver accidentally drove his car into the hole, but escaped with cuts and bruises. His car was pulled out several days later.
By Sept. 30, Mayor Jim Watson is asking for an inspection of all infrastructure located along “critical” city roads, and an independent investigation on what caused the Highway 174 failure is due in 90 days.
If faults are found during the inspection, repairs will be made immediately, the city stated.
