I think they're trying to fix the issue where commercial vehicles exiting Deerfoot N.B. to McKnight E.B. have to immediately cross 3 lanes of traffic to reach the turn lane for Aviation Blvd.I am not a highway person but some of these improvements seem pretty weird, non-standard and unconventional - like this one at McKnight:
Essentially it's a 3 lane off-ramp merging into a 3 lane road with a signal to control it, but only for east-bound traffic. I don't think I have seen any ramp this wide on a Canadian urban highway in any of the bigger, busier cities (Toronto, Montreal or Vancouver). And only for a single direction too, the only ramps close to this number of lanes often have both directions access.
I suppose the capacity is increased with cars now able to queue to access McKnight, but if this was a no-brainer, why haven't others done stuff like this? Why aren't more intersections like this even on Deerfoot?
It always seems like we are re-inventing highway designs/interchanges here for no reason rather than creating a standard, predictable practice or just take a model that works fine in other places and apply it.
There's all sorts of surface transportation/logistics industry in there including large Courier Warehouses and Canada Post's Calgary Mail Processing Plant.
That intersection's a real zoo at times with a line of semi's merging from the right and trying to slowly push across traffic .
I believe the McKnight Boulevard Transportation Study recommended a flyover of 12 Street N.E./Aviation Blvd long-term.
This looks like a short term band-aid solution until then.
