US Route 12 in Walla Walla County, Washington
Amaury:
So, when I took my drive to Dayton, Washington, on Tuesday, I drove a section of US Route 12 I've never driven before. This section: https://goo.gl/maps/xKi1E5PvujjzC4mo6 From the Wallula Junction to the exit for Washington State Route 125 in Walla Walla, Washington. I drove it eastbound. I came across a sign stating that a new traffic pattern would be starting on March 23, 2023. The sign is a little before milepost 317; the new road itself is a little after milepost 317. It doesn't seem to be a temporary alignment as I saw a milepost sign on the new road, so it looks like it will be permanent. It wasn't totally clear where the other end came out, but right here is where it starts: https://goo.gl/maps/m67NonrHgiQVmrBe7 It's more completed than that now, of course.
What project is going on here, and what is going to happen with the old alignment? Will it become US Route 12 Alternate, like US Route 97 Alternate in Chelan County?

It comes out at MM 328 where the existing 4-lane ends WB - https://goo.gl/maps/wHxbWxEEerhFqcd79
project: https://wsdot.wa.gov/construction-planning/search-projects/us-12-nine-mile-hill-frenchtown-vic-build-new-highway
it appears the new alignment will be a full freeway. The previous project east through Walla Walla did not result in US 12 ALT, etc. so i would be surprised if this one does when completed.
Amaury:
Since it likely won't become an alternate alignment, I would guess the old alignment just becomes a county road known perhaps as Old Highway 12, like Old Highway 97 in Okanogan County.

Glad this is getting done, I last drove that stretch when I was working in Richland a few years ago, and hoo boy did that need upgrades.
