Interstate 42 (W)

Are they just gonna do this piece by piece?

It's Oklahoma. You know they are.

On Google Maps, S. 4170 Rd. is also listed as Gregory School Rd. Is that an official road name? I didn't see any street signs on Street View with the Gregory School name.

The schematics show raising US-412 over the cross road... wouldn't it be cheaper and less impactful to simply raise the road over and construct a 2 lane bridge as opposed to two 2 lane bridges?

Many road names in Oklahoma were assigned in the late 1990s to make 911 dispatching easier. Most of these were part of a systematic countywide numbering system, which is probably where the name 4170 Rd. came from. Before that, though, the major roads had names used by the locals, which didn't normally appear on signs (because there weren't any). I wouldn't be surprised if everyone's mail said "4170 Rd" on it but they told everyone "I live on Gregory School Road".

They probably don't want to impact the driveways of the two properties to the north of the right-of-way.

True. For some reason, I was just hoping given all the buzz around the announcement. Maybe they were gonna do it as a larger scale project.

Based on the geography, it appears US-412 is elevated higher than Gregory Road.

Also today, Gregory Road is pretty wimpy, so I was trying to figure why this one than any other and noticed that the Tulsa Port of Inola is a straight shot south of Gregory.  The roads don't fully connect today, so I wonder if they have plans to upgrade this road south of US-412 to service the port. THat would make this exit plan more logical.

The only hope for Oklahoma not doing these upgrades along US-412 in very slow, piece-meal fashion is if the state gets awarded big federal DOT grants to accelerate the project. They can't get it done with their meager gasoline tax revenue. Federal grants are why the "traffic-henge" interchange in Tulsa (I-44/US-75) is finally seeing some new progress.

The current plan by ODOT on the 8 year plan for the six interchanges is:

2026:
RD 4190
US-412B

2027:
265th E Ave
305th E Ave

2030:
RD 4170
RD 4240

I'll bet ODOT has at least some federal funding earmarked for those interchange projects (if not a lot of federal funding).
