Yeah... just don't do it during normal business hours. People got stupid when they opened that up... ALL traffic went there like they are going so much faster now.
In reality if you go down the "old" bottle necks there is hardly any traffic and you can just fly. I'll take that extension until I hit a red light or some traffic then I hop over to Albertson's Parkway or La Neuville (same road actually, might tax dollars) after that it's smooth sailing right back to Ambassador or any of the other various roads you need to get on.
