Prob never will never happen but I"d love to see Deerfoot be realigned over the river. The land to the east going north just before the river looks very suitable to use.

Are they really creating an intersection at 10th Ave And 14th Street? Will this be a bridge over 14th Street? That would be great if its true, it makes more sense to drive down 10th Ave to get to Bow Trail.

It's supposed to be an intersection controlled with lights, and it was supposed to have been done by now.

What the hell??!!

Sorry for the language, but this has to be one of the worst-designed interchanges in Alberta. What a waste of space! Also, the weave zones on Crowchild may be a problem.

Err... the former is a direct result of preventing the latter.

That, plus noise abatement. No one wants to live right next to a freeway, and we've seen time and again what that does to local property. Having some semi-natural greenspace around it is a fantastic idea that benefits everyone.

hmm, it'd be nicer if there was a bridge over 14th for free flowing traffic, but I guess that would cost too much money.

I know what you mean, because I was thinking about two flyovers (or under). Cost more, yes, but that would avoid any weave zones. Also, I wonder if another such alternative was considered by just have a regular cloverleaf, but adding a collector road next to Crowchild and two bridges to eliminate weaving on and off Stoney. This weaving could be moved off the main road of Crowchild. Not that I want to beat a dead horse..

This winter has taken its toll on the roads. Are they ever in bad shape. The potholes aren't so bad, it is the bumpiness of the frost heaves that has me hanging on to the steering wheel.

Anyone on here have any knowledge of an updated ETA?

edit: city website says:

This is for all Sunalta improvements though (boulevard and sidewalk widening, new sidewalks, new trees, 10th ave/14th st intersection work)

If you've ever wondered what it's like to live in other prairie cities in Canada, go for a drive in Calgary this month.

I'm actually surprised the potholes aren't much, much worse. Give it another year or two of frost heave like this, and hilarity ensues.

That thing is the size of a small town. How much space does that thing take up?

What happen in the suburbs, stays in the suburbs. They can keep their shitty design ideals. BLAH.

I'm just glad they used the space they bought 40 years ago properly. Why NOT make traffic flow better by using the space available to up the design speed of all the ramps?

Anyway, I did a rough estimate of the area affected by the grading of the entire interchange and it came to approximately 775,000m2.

Crow/Stoney is basically a modified clover with an attempt to make the weave distances longer. Considering the land available and additional bridge costs, I think the traffic engineers screwed the pooch on this one. Wouldn't be the first time.

I foresee a massive rebuild in the future, similar to what Montreal is doing with some of their interchanges. The long nightmare which NW residents have had to put up with isn't over by a long shot.

I'll agree with you that it's certainly an odd design, but I'm not going to denounce it as I haven't seen the methodology behind it (traffic numbers, level of service indicators, etc.)

I guess we'll have to see how it does once it opens before we can properly rage on it.

I'm guessing that the Crowchild interchange is going to work just fine. I don't know exactly why they just didn't add some flyover ramps, but it should work.

There are no weave zones for the primary road. The weave zones for the secondary road are quite long.

The number of left turners was probably low (relatively), making no reason to put in higher speed ramps. It's also probably significantly cheaper. Those are likely the reasons.

The WB weave is 200m long and the EB weave is 250m long...I'm not sure how adequate that will be on a road like Crowchild. For reference, the minimum weave length on Stoney Trail is 500m.

Hmmm, I thought they were longer than that, but still a much better design than an actual cloverleaf.

Looking at the interchange design, at least there are good acceleration lanes for traffic merging onto Crowchild to get up to spped limit.

Also, speed limit is only 80 vs 100 on Stoney Trail, that would make a significant difference in weave length I think.

I think if there's one thing we all can agree on here, it's that people in Calgary are terrible at using long merge lanes to get up to speed BEFORE merging. 16th Avenue onto NB Deerfoot gives me freaking nightmares.
