I was going to post the City's website that has traffic updates but it did not have this major incident 15 minutes after the fact. I have found that the City's radio traffic broadcast at 97.5 is very fast updating and is usually accurate. It may only relate to the south but if you use deerfoot daily maybe check it out. I put it on to decide which way to get to McKenzie towne everyday.
The city's link to their traffic page is:
