Looks like they are still there, though I'm not sure if they were the enhanced mile markers like shown in the most recent streetview back then, so that may be newer.

Still good to know that I-84 has some now too though! Thanks for letting us know. Were the ones on I-84 regular mileposts, or the enhanced type with shields and cardinal direction like the 217 ones?

And I bet it's still the first Interstate that has them. I know for a fact that the whole of I-5 and I-205 didn't have them as of 2019 at the very least.

They were regular mileposts, without the shield. I'll try and get some pictures next time I get out that way.

It kind of makes sense to omit the shield on the 84, given the 30 duplexes for the majority of the route. Avoids milemarker 'overloading' (imagine it on the 84/30/395 triplex!).

--- End quote ---
Normally, the blue enhanced mile markers leave out all the multiplexed routes and only have a primary route on them, so just I-84 in this case (imagine 8 other routes with I-465). If itís between two interstates, Iíve seen them either both on or just the one with exit number continuity on.

--- End quote ---

In fact, there shouldn't be more than one route on them, part of the point of having the route on there is to identify which route's mileage the signs refer to in a concurrency.

In Oregon, it'd be fairly moot, as the mileage doesn't belong to 84 or 30, (or 395 when joins the fray). It's 2, then 6.
30 effectively wouldn't be that affected, with the only noticeable discrepencies coming from the Mosier-The Dalles, Pendleton, La Grande, and Baker segements, for a total of roughly, what, 3-4? miles between I-5 and the respective crossings into Idaho in Ontario, as ORH 2's 0 is in Portland. And since 395 doesn't have its own undlying ORH number while it's on the 84, it doesn't care, as its next 0 is in Pendleton.
(This also puts 730's 0 at I-5, incidentally)
(ORH 6's technical 0 is at US 730, but like ORH 53 at US 26/OR 35, its posted 0 is in Portland)

Technically you're correct but 2's mileage starts at the same place as 84 and 6 continues the mileage from 2, so it's effectively 84's :P

Theyíre pretty inconsistent from my observations. Some concurrencies have both routes, like 71/75, 70/71 and 271/480 (last one looks really bad with both) on the mile marker, while some have the dominant route only, like 465/74 and 70/76. I prefer the single route version.

--- End quote ---
What I would do is: the mileposts go exclusively to the route of the higher class and then the lower number. (i.e. if you have Interstate 80 and 90, mileposts favor Interstate 80. If you have State Route 2 and Interstate 80, mileposts favor Interstate 80). I think this makes things a lot more consistent and clear.

Generally, if only one of two routes in a concurrency in the same class is chosen to be on the mile markers, it's the one with exit numbering continuity in the concurrency. I made a thread discussing conditions which route should have exit number continuity in an interstate-interstate concurrency a while ago, if we continue this discussion somewhere else.
