Which interchange is it? The one on the East side of town or the West side?

The west side (the one with a convoluted route to get onto I-40 EB from Gary Boulevard).

[Bobby5280]

The EB I-40 off-ramp to Gary Blvd looks kind of like a movement in a turbine interchange. The off-ramp's bridge going over the I-40 main lanes looks old as hell. The design looks like it dates back to at least the 1960's, if not older. Unless the entire interchange is re-configured into another type of design it looks like that old bridge may be the only structure that gets replaced. The other ramps might get some new pavement.

I really don't like the WB I-40 arrangement in that location. The on-ramp from Neptune Drive onto WB I-40 is really close to the next exit ramp from WB I-40 to Gary Blvd. The end of either ramp is only 1000' apart. I'll bet serious traffic weaving issues occur there, even with Clinton being a small town. In a bigger city those ramps would have to be braided to eliminate the weaving conflicts.

That video from 2019 is pretty informative. The proposal would get rid of the turbine style loop ramp from EB I-40 to NB Gary Blvd. More importantly, exits 65 and 65A would effectively be combined into one single exit. That would eliminate the dangerous weaving issues present on WB I-40 between the exit 65A on ramp and exit 65 off ramp. I'm not a big fan of roundabouts. Motorists will have to do a good bit more back-tracking when going thru them. But that section of Interstate will be safer.

That design from 2019 has since been replaced with a different design.

ODOT actually went with a diamond interchange for Gary Boulevard with a Texas turnaround. The Texas turnaround will be used for traffic heading to 10th Street/Neptune Drive from westbound I-40 as well as accessing eastbound I-40 from 10th Street/Neptune Drive. Yes, it will still be one interchange, but a different design than what ODOT preferred from the 2019 meeting.

Thanks for the update. I knew there were changes but I could not find them.

[Bobby5280]

The updated changes look like a much cheaper design. It still removes the weaving conflicts on WB I-40 currently present between exits 65A and 65. But the trade-off is traffic exiting WB I-40 to Gary Blvd will have to merge with vehicles coming from Neptune Drive to get on I-40.

The U-turn movement along Gary Blvd makes up for two I-40 ramps being removed at Neptune Drive. It isn't much of a bonus, considering the extra distances vehicles coming to/from Neptune Drive will have to cover. I think the short extension of Gary Blvd down to Chapman Road makes up for that a bit. I can't tell if the new I-40 exit with Gary Blvd will have traffic signals. The presence of signal lights could influence how locals access I-40, either using Chapman Road or Neptune Drive.

Someone wants their money back lol...

There was a Meatloaf song called "Life Is a Lemon and I Want My Money Back": https://www.youtube.com/watch?v=KanegVORJYE. Maybe that pertains in this case.

Road Guy Rob got a shoutout from the OTA.

A public meeting is coming for a project on I-40 at MacArthur Boulevard and Meridian Avenue in OKC.

It does the following:
-Widens I-40 from six to eight lanes (from three to four lanes in each direction)
-Rebuilds both interchanges to a single-point urban interchange (SPUI)
-Adds an auxiliary (merging) lane in each direction between interchanges

[Great Lakes Roads]

ODOT Nov. 13, 2025, letting:

- Interstate 40 rebuilding and widening from east of Kickapoo Turnpike (I-335) ~MP 171 to 1/2 mile west of McLoud Road (OK 102 North) ~MP 175.5. Replaces two overpasses (Harrah Newalla and Fishmarket Roads) and removing one overpass (Arena Road) while also reconstructing the Harrah Newalla Road interchange in-kind.

[Plutonic Panda]

The new eight year plan for ODOT. is out and it is depressing. So much so I don't even feel like going and grabbing the link, but you can just type the website up and look it up. It's not hard. Lots of projects are pushed back and delayed. Not really too mad at the Oklahoma Department of transportation, knowing that the state doesn't properly fund essential services like transportation or education.
