There is an open house planned about the SLT project at Southwest Middle School in the cafeteria on Wednesday, October 9th at 4:30 PM: https://slt-ks.ksdot.gov/. Will anyone be able to attend?

Please tell me those inner loop ramps at the new K-10 and I-70 interchange will be separated from the EB I-70 mainline via a C-D roadway.

You would like to think a major DOT wouldn't put in an interchange design that literally almost every other DOT is working to eliminate.

I would hope KDOT is just floating this as a placeholder before coming up with design options for the interchange. The design in the article looks more like something from the 1950's before we knew how to design high-speed interchanges. I know most tolling in Kansas is electronic, but this interchange would be busy enough to require manned booths until ETC becomes standardized between states.

This is a very old quote string and the original link appears to be paywalled, so I can't tell if the original I-70/K 10 interchange design is still current, but I just wanted to share the most current map from the SLT project website: https://slt-ks.ksdot.gov/wp-content/uploads/2022/09/2022-05-10_SLTW-Project-map-1.jpg

I typically endorse C/D roads for cloverleaf configurations, but I don't see the pair of loops on I-70 EB as a huge problem here. Neither of those loops should be that busy, and the dominant loop movement (K 10 WB to I-70 WB) looks like it will have a flyover.
