It will be another slow commute for drivers who use Macleod Trail to get into downtown Calgary on Thursday morning.

A water main break on that was detected by city crews at about 3 a.m. Wednesday morning shut down two lanes of the road between 13 Ave. and 15 Ave. S.E. for the commute.

Crews spent most of the day on Wednesday locating the break in the 100-year-old pipe.

They’re now just starting an operating to dig down and get at the pipe to conduct repairs.

City crews say that improvements have drastically cut the amount of issues they need to deal with every year.

“We used to have around 1,800, but through proactive water main replacement and an active retrofit program, we’ve got that down from around 1,800 to about 250 per year,” says Lee Dupras with the City of Calgary.

Two other lanes remain open, but delays are expected due to the volume of daily traffic on Macleod.

Drivers are asked to avoid the area and find alternate routes to take to get themselves to work.

Detours have been set up in the immediate area.

Crews expect to have the break sealed and road reopened by about noon.
