First Diverging Diamond in the US Opened Today

[City]

That interchange just made diamond interchanges awesome. I usually like more complex interchanges (which this is), and this is one nice interchange. I am sick of normal diamonds (just about). But this just put some fresh thoughts about diamonds into my mind. This is one great interchange!

My real-time trip through the diverging diamond a couple of days after it opened.

[agentsteel53]

so how many drivers know this is permanent, and not just some wacky construction zone?

[Rover_0]

Interesting stuff.

[Hellfighter]

I so wanna drive that now!

Diverging Diamonds are coming to SimCity soon!  See this topic in Fictional Highways for the discussion.  Please keep this thread on topic!

This just in, Indiana is planning on building this type of interchange in conjection with the East End Bridge Project between Utica and Louisville in Southern Indiana.

Looks interesting. I doubt I'll be seeing any in Newfoundland any time soon.

I'm not sure a DDI would be better than just removing the loop in the SE quadrant and leaving the interchange as a six ramp partial cloverleaf; I'd like a few more details than the article provides regarding traffic operations and the cost of widening the EB IN 265 overpass.

I looked into it a bit more and saw that the website for the project had an illustration of how the interchange would look and included a video of how the intersection would work with traffic.

The simulated vehicles at 2:44 in the first video are worrisome.

Good thing the train had already just gone through...

[Bryant5493]

^^ Yeah, I agree. That railroad crossing would work better being grade-separated than at-grade.


Be well,

To me the length of the left side driving part of the interchange looks too long.

I'd also like to see how the northern half of the interchange is performing while a train is blocking the south side.

I would too.  And, yes, I agree with Bryant that grade separating the RR crossing would be a good thing assuming that the level of rail traffic is sufficient enough to warrant it.  If the track only sees one train a day, the grade crossing is probably fine.

MoDOT is now planning another DDI for the US 65 interchange with MO 248 in Branson:

Bumping this thread up a little.  It seems Google's updated the StreetView in Springfield, MO, and you can now take a virtual drive through the I-44/MO-13 Diverging Diamond.

Enjoy!

I have a video of me driving through it just a couple of days after it opened.

The second one is now open, also in Springfield MO. And they just started a third.

The one in American Fork UT will be open in a month.

MO now has a total of 7 planned, under construction, or open.

Where are the other ones in Springfield? I have family there, so I visit there a lot and I'd like to know where to look for them. I really like the one at I-44 and MO 13.

[bugo]

And I still say the name should be changed to "Crossover Diamond Interchange" since it's more descriptive.

I prefer the term "Death Diamond".

James River Freeway (US 60) at National. There is also a tunnel under National to access Cox Hospital

The third just started is at Chestnut Expressway and U.S. 65.

And I still say the name should be changed to "Crossover Diamond Interchange" since it's more descriptive.

The US DOT prefers "double crossover diamond."

A diverging diamond is one of the alternatives for the I-590/Winton Road interchange.

And that's what it will be reconstructed into.

[nyratk1]

I'm surprised NJDOT hasn't graced us with one of these to confuse drivers even more.... heck we don't even have a real SPUI in this state yet.

Drive up to CT Exit 48 off the Merritt Parkway with CT Route 111.

For SPUIs, there's also NY 25/Suffolk CR 97 on Long Island.

I live about 3 miles from that RR crossing, and I have NEVER had to stop for a train.
