Iconic duos

[thspfc]

There's a meme that says "name a more iconic duo, I'll wait". What if we do that with roads? For example, I nominate I-80 and US-6.

[Buck87]

I'll go with I-80 and I-90 for their long concurrency, as well as their status as the longest 2 interstates

[webny99]

"Iconic" might be a stretch, but US 11 and I-81 could work.
And for western/central NY in particular, US 20/NY 5 and their long multiplex across the tops of the Finger Lakes.

I feel like we've seen this thread before, but to name another one: US-1 / US-9

[I-55]

I-20/59 in AL

[Max Rockatansky]

US 395 and US 6 on El Camino Sierra. 

[STLmapboy]

70 and Farty.

[TheHighwayMan3561]

I-94/694

[US 89]

US 89/91 are a fairly well known pair in Utah. 6/50 too.

[ilpt4u]

I-39/US 51

[epzik8]

US 1-9

Maybe this is more infamous than iconic, but (former) US 66 and I-40 come to mind. My mom lived in NM in a town that was by-passed by I-40, and the only reason it survived is the Uranium mines. Now that that is gone, the town is slowly shrinking. (If you can guess the town she grew up in, you get imaginary brownies ).

[Max Rockatansky]

US 1/CA 1 and US 1/A1A. 

[Henry]

I-90/I-94, both in downtown Chicago and further north in WI (from Madison to Tomah).

[Ned Weasel]

New Jersey Turnpike and Garden State Parkway
I-35E and I-35W

If you want to go farther south, I have an iconic trio for you!

[ozarkman417]

US 71 & I-49

[US 89]

Grants?

[CNGL-Leudimin]

US 20 and US 6, the longest US Routes. In fact which one is longer is not well determined.

[hotdogPi]

The reason why US 1&9 was on the "Roadgeek Memes" thread was because the routes share the same sign. This isn't the case for any of the others.

[SectorZ]

MA 4/225. I mean it must be to be exist as it does, right?

It happens sporadically here as well - here's an example (although most of the signage looks more like this).
