I remember reading that area was chock full of construction waste/debris under the roadway, which was only revealed by the flood. I can't find an article about this, though.

For the very first time in my 20+ years living in the greater Calgary area, I today accessed eastbound McKnight Blvd from 48 Ave NW. Wow! Dangerous! And difficult! Something needs to be done with that intersection! Maybe a traffic circle?

McKnight as a whole needs some serious work. Most noticeably that T intersection with John Laurie

I've always wondered how that works, I see people sitting there every time I drive by and it looks like a long and frustrating wait. The volume on JL turning onto McKnight is just too heavy for any useful connection to 48th, probably best to just go the long way around lol.

I’d considered it, but I was following my brother in his vehicle ahead.

Northwest Calgary residents want improvements to ‘dangerous’ intersection | Globalnews.ca
You don’t see intersection designs like this anymore. In northwest Calgary, three main roads converge at a very unusual T-Intersection: McKnight Boulevard, John Laurie Boulevard and 48th Avenue.

Thanks.
Would be such an improvement.

Looks like quite a few property impacts. Hopefully those property owners will understand the ultimate goal and not put up too much of a fuss.

I count 9 properties.
I wonder if the City is buying them if/when they come up for sale ?

Highways clear-cutting through residential neighbourhoods have famously always been met with very accommodating impacted homeowners
Of all the east-west cross-town dreams that transportation engineers have had for decades in this city, McKnight/John Laurie is one of the weirder ones for me. It's strange that they were actually successful and got it connected but di so super weirdly, to this whole discussion. Strikes me as a super-bizarre design they ended up with - in keeping with Calgary road standards, it seems simultaneously both over and under-built.
Before moving to the expensive ultimate design with a bunch of expropriations, a large traffic circle or signal would work fine here, but even shrinking 48th Ave to be a right-in-right out design and just having slow curve in the existing footprint would be an upgrade.
Would be interested to know the back story of how they ended up with the design they did and why they didn't plan for a more normal connection in the first place.

Traffic circle with RRFBs on the JLB end seems great

What is an RRFB?

The plan was supposedly very popular, with 90% support from the North Haven community in 2005. But the City isn't willing to fund it yet.
North Haven residents want action on increasingly dangerous northwest intersection
Frustrated with a dangerous intersection that’s the only way out of their northwest community, residents in North Haven want the city to fix a growing problem…

There are lights at 4 St already...another light that is 85% green time really shouldn't be a problem.
Right in right out would be even better, but it looks like it isn't currently possible to do a U-Turn at the 14 St lights; it's probably too tight to achieve that without eliminating the pedestrian island, but if they did they could make an entire island surrounded/protected by dicks! https://maps.app.goo.gl/obetK725GU6cA97p7
But really that ped island adds very little value since it doesn't have a signal in the middle - it's actually more of an annoyance for most users, especially in the winter, so they should nuke it! But keep the dicks, they're great.
