The more interesting part of this article/video is the news that they will be closing I-70 for 10 months in 2027 and that US71 will be the detour. I can already see the complaints about those traffic lights coming. Those 10 months will suck because I'm guessing the traffic will increase on I-435 as well.

MoDOT held a public meeting last night in Boonville for the Boonville-to-Rocheport portion of Improve I-70 and posted the plans to the website, although we don't get a roll plot or anything like that: https://www.modot.org/improvei70/boonvillerocheport

The only notable upgrade to any of the Boonville interchanges is the addition of a roundabout at Route B and Americana Drive, about 400 feet north of the ramps to and from westbound I-70: https://www.modot.org/sites/default/files/documents/Roundabout_Overview_Board_36x48_20scale.pdf

U.S. Route 63 Highway Realignment in Osage County

This project will realign U.S. Route 63 from south of U.S. Route 50 to the Maries River in order to address safety concerns and improve the flow of traffic. In the past 10 years, this corridor has seen 190 crashes that have resulted in seven fatalities, 12 serious injuries, and 80 minor injuries.

Construction could begin as early as fall 2027 and be completed in December 2029.

This has been needed for a long time--US 63 is a very annoying drive from the US 50 junction south to about the Gasconade River bridge, and this is one of the worst parts of it. Lots of semi traffic, lots of hills and curves, several small towns, few passing opportunities. Ideally the entire stretch needs four-laned as far south as Rolla.

MoDOT released updated plans for the Blue Springs to Odessa section of Improve I-70, including plans for the Odessa/MO 131 Interchange and the Bates City/Route D Interchange.

Introducing the NEW interchange design, the divergabout, where you combine two roundabouts with a diverging-diamond design!

Don't tell |tradephoric|.  He'll be triggered by the assertion that these designs are proven to reduce the number of major crashes.  And bonus points go to the presenter for bringing up the number of conflict points.

This is about as Missouri as it gets. They might as well serve KC BBQ with a side of Springfield Cashew Chicken when this opens.

Also, this is my 1,772nd post. That number matches the elevation of the highest point in Missouri, Taum Sauk Mountain.

Honestly this post made me instantly think: Indiana, INDOT, and Carmel, IN. Do the Hoosiers know of this interchange type and are they building them?

Does Missouri have a big a thing for roundabouts as Indiana?

What will they think of next? The RoundaSPUI?

Missouri has as big a thing for DDIs as Indiana has for roundabouts.

But yes, Missouri has also noticeably turned up the dial on their roundabout love in the last decade or so.

Take note, Missouri:  the next step in cheap interchange designs that incorporate roundabouts should be something like the cloverabout.

They got 3/4 of the way there in the late 2000s with The New I-64 project.

Well, a single point roundabout is basically just this, so it has already been done

They definitely have some interesting interchanges. I'm impressed by their creativity.

Missouri has two of those divergeabouts in the KC area: One at US50/MO291 interchange in Lee's Summit and the other at I-49/E 155th St near Grandview/Belton area.

Another one in the area (not a divergeabout) is the I-35/MO-152 interchange in Liberty.

We also have this thing (parclobout? Rounda-parclo?) just east of Jefferson City.

That's just a parclo with roundabouts instead of stoplights.  Su-u-u-uper common in Europe, right?
