Found the Arizona DOT page addressing this project; it says the ramps will be for the 67th, 51st, and 43rd Avenues. Construction is actually set to begin in the autumn of this year.

ADOT has actually just advertised the contract for 43rd and 51st Avenues (TRACS number F042401C).

Edit:  Because of the form of phased construction ADOT has employed at these interchange locations, which routes current mainline Loop 303 traffic down what will eventually be the exit and entrance ramps, the traffic control is minimal and covers just seven sheets in a 643-page plans set.

While I know 303 will get a proper interchange with I-17 sometime in the future, I still don't really know what these are for.,-112.1417714,3519m/data=!3m1!1e3

Looks like they're planning for various diamond interchanges along the loop to surface roads that will be built as the area gets developed. The entirety of CR-215 around Vegas was built this way.

Not the entirety of the Las Vegas Beltway was constructed this way.

The portion of CR-215 between the southern I-15 heading west and north to about Tropicana Avenue originally opened along what is now the frontage roads, and the freeway was eventually built in the middle. The portion of CR-215 between roughly Aliante Pkwy and the northern I-15 interchange was built more on the freeway alignment but temporarily diverted along the eventual on/off ramps at most of the interchanges to access the cross streets until the overpasses were constructed. Most of the rest of the beltway was constructed as actual freeway directly (including most of everything currently signed as I-215), or using some other interim measure.

The brown Loop 202 signs have all been replaced.  At least I don't recall seeing any in several years.  I believe there are still one or two black Loop 303 signs still around, at least as of last year.  I try to avoid the 101 like the plague, so I have no idea if there are any blue signs left.  :)

I remember the last (badly faded) survivors of the brown Loop 202 shields were at Country Club (SR 87) and the Loop 202 Red Mountain in Mesa. Not sure if they are still there.

I don't believe they are, either on the freeway itself or on Country Club.

In any case, you'd think that ADOT would have learned its lesson from the 1950s & '60s, when all state and US highway signs were color coded, depending on the direction.  I remember seeing a lot of them fading by the time that was discontinued in the mid '60s.

The group of button copy signs on Country Club south of the 202 was the last to have brown shields on them I believe. I can confirm they were basically completely faded for quite a few years before ADOT finally replaced them.

Last street view from 2019 before the shields were replaced:,-111.8396149,3a,75y,0.53h,95.02t/data=!3m6!1e1!3m4!1sAHO08KEoZaj6Vkw9JR286A!2e0!7i16384!8i8192

I was noticing that I-17 on and old map by Enco, was not built over US 89 like you would think.  It appears US 89 had a more convoluted alignment between Phoenix and Flagstaff serving Prescott and then having an Alternate route to head back to I-17 of today.

US89 doubled back east along US 66 instead.

Also AZ 85 north of Gila Bend was also part of US 80 as I-8 replaced AZ 84 to Casa Grande. Though itís odd AZ 84 was not US 80 ALT or another X80 designation at the time I-8 was not part of history as I am sure it was used by cross country motorists as a de facto bypass of Phoenix back then.
