I believe that is part of Phase III or IV, after they build a dedicated elevated curved ramp for EB Glenmore to NB Deerfoot.

This is the ultimate plan for Glenmore & Deerfoot, from a 19(!) year old study:

Started summer of 2023 other than 64th which started a few months earlier. I believe the North sections are supposed to be done this year. Glenmore 2026, and Southland/Anderson/Ivor Strong bridge 2027

Ahh yes, I remember the "6 new bridges over 11th street" plan

Cut at the 11th hour:
- Rebuild of Deerfoot/McKnight including a EB-NB flyover
- Improvements to 16 Ave between Deerfoot and Barlow
- It was looking like the 128 Ave NE half-diamond contract was going to be awarded, it was not
- Cut somewhat earlier was the Deerfoot/Airport Tr rebuild that will see a WB-SB flyover

You're looking at around $2 billion to bring Deerfoot to a modern standard. Busiest road in Canada outside of Toronto and woefully unsafe... since I guess they somehow need justification for throwing a few bucks at it.

Worth mentioning that the most recently completed study (2 or 3 years ago) still recommends this plan.

[#-3]

With the extra lane on Deerfoot, I'd like to see something like they have in SLC, not necessarily toll, but double solid lines dividing the left lane from the rest of the road for a couple of tight stretches.

Example if you are travelling North you cannot enter / exit the left lane;

From the Anderson off Ramp to the Heritage Meadows on Ramp.
From 17th On Ramp, to the 16th On Ramp
From the McKnight Off Ramp to the Beddington Off Ramp.

I think this would really give the left Lane the opportunity to keep flowing in spots were it really bottlenecks right now. It would be cool if they had something like that in mind, but seems the plan will be just to expand the road and let if fill backup with new suburbs.

[Acey]

It's just the general motion of exiting traffic having to cross entering traffic, aka weaving, that destroys the flow of mainline at those locations. At Deerfoot's volume, the only fix is braided ramp/basketweaves like what is currently going in southbound between Southland and Anderson/Bow Bottom.

Pinning traffic in the left lane would have no tangible impact, unless you could separate the left lanes from the rest of the mainline... aka collector-distributor system.

[sleepingmoose]

I'm probably just a little gun-shy after the mess at the South Bow River bridges near Lake Sikome over the last 10 years, but they're not going to shut down the Ivor Strong to 'refurbish' it once the new bridge is done next to it, are they?

[ken0042]

I would expect they would shut it down to refurbish it. Looking at the plan both spans over Anderson are "new" bridges, so Deerfoot will be down to 2 lanes each way for a while. It would make sense to do a refurb while they can.

Keep in mind the WB span on Stoney- that bridge was already 15 years old. They also took the pedestrian portion and turned it into vehicle traffic.

Different rules/guidelines apply. One is a City project, the other was Provincial and had different weave distance requirements.

Might be nice in SLC but as a Calgarian, I have every right to merge my F150 onto the highway and immediately into the left hand lane so that I can do 2.8 kmh faster than the traffic in the other lanes.

You could even put dividers at the 16th to 17th section to isolate the single lanes. Getting around the down town exists would be quite valuable. By having dividers you’d get rid of the adjacent lane changes and the speed delta between the moving lanes and slow lanes

Perhaps wee need Deerfoot driver quality filters, like if you can't get within 10% of merge speed, your Deerfoot entry is denied with an ejector plate.

[Icantwhisper]

As much as you improve the roads, Calgary will always produce a crappier driver.
Once this is all complete the # of people getting confused and trying to cross 3 lanes in 100m will nullify any traffic flow improvements.
Exits are too complicated for the idiots on the road, two choices seems to be a struggle for most.

Just make it like the movie Speed.

GPS detects that you hit an onramp? Bomb activates. Can't keep your speed up and you're eliminated

So long as it's within merge speed +10%, not +/-10%. People merging on at slower than the prevailing flow of traffic (let's say 90 KM/H to everyone's 100 KM/H) is still hazardous and pain in the ass.

I figure within 10% is ok, because you may be anticipating a gap and have to go a bit under to get in.


Amused your issue is with this, and not the ejector plate(which would be hilarious to watch, particularity in winter).

I'd take 90 all day long, its the 60 guys I want to murder.

I've found the most satisfying way to get back at the 'way too slow' driver is to get in front of them and go even slower. How do you like them apples. Deerfoot 100 kph left lane guys. Oh I'm going 90 in front of you now. Annoying isn't it? Takes a minute until their right lane change signal comes on and they start moving to go around then i floor it back to human non-tard speed .

It's a nice idea but the roads may change but Calgary drivers will not. There are way too many drivers in this city that don't give a #### about rules or being courteous to others. Still always going to have the people that move in the left lane to take advantage of the flow if even for a short duration and then cut right all the way across abruptly to merge off just so they can cut 60 seconds off their 50 minute commute.

What? Hell, I endorse the ejector plate idea!
