I didn't have time to pull out my camera upon seeing it, but there is at SW 6th Ave at Broadway in Portland a shield assembly with an I-405 and a (cutout) US 26 shield, replacing an older button copy sign.
			
			
			
				Is this any different from the cutout US 3 shields in Massachusetts?
(other than the number and location, obviously)
			
			
			
				So did they just copy the far superior state to the east?

Or is it something different?

Similar setup, minus the third shield. 
Facing west, the assembly has 
...........---->
NORTH...|....WEST
(I-405)-----(US 26)
.....|...............|
.....|...............|
With the reverse just behind that facing east, coming off of Broadway. 
I don't recall the numbers being obnoxiously large, but it's hard to tell having just caught a glimpse of it. 
Also, Idaho's landlocked. Oregon is superior just by having a coastline ;)
			
 
			
			
				So the one spotted in Portland is a borderless cutout (meant to go on a BGS), rather than like the ones in California, or Virginia (also bordered cutouts, without the "US" on Caltrans-spec markers)?
I see such borderless cutouts in places not known as cutout heavens, such as Indiana, or even in Maryland (just saw a pair at the exit from the park-and-ride at the junction of MD 424 with US 50/301).  I've always thought those were contractor errors, as the US 26 cutout in Portland and the one in the photo from Idaho might be.
I know Oregon resists "Californication", but Caltrans-spec cutouts would be a nice import.
			
			
			
				The Caltrans spec would be ideal, but I'll take the borderless ones any day over the black square variety. I'll attempt to get a photo next week.
