U.S. Highways That Don't Parallel Any Interstates

[sprjus4]

Do any U.S. Highways exist that do not parallel any interstate highway throughout its entire course? Essentially, no interstate highway was ever built specifically to follow the same path of the U.S. Highway for more than 5-10 miles. That so-called U.S. Highway serves as the main route for thru traffic, and there's not an interstate paralleling it for thru traffic to use throughout its entire course.

If the U.S. Highway follows generally parallel to another interstate going the same direction, but is a significant distance (15-20 miles) away and that interstate would never compete to the U.S. Highway (I.E. they split off in both directions, and never cross or touch while being "parallel") that still counts as the interstate was never intended to parallel that particular road, it just happens to head the same direction for a portion of the route.

I can't think of any examples of the top of my head, but I'm just curious as to if any exist.

EDIT - Since most of the routes that follow no interstates whatsoever have been mentioned, if less than 15% of the entire route (take how much mileage the route parallels / overlaps an interstate then divide by the entire route's mileage) parallels or follows an interstate highway, it can qualify for this thread.

US 131, unless you count the few miles of concurrent unsigned I-296.

[Big John]

US 151 is not concurrent with any Interstate.

[TheHighwayMan3561]

US 169 comes to mind.

Western US 2

[sprjus4]

US 169 comes to mind.

Close, but about 7 miles near St. Joseph run parallel to I-29, and there's a 14 mile concurrency with I-35 in Kansas City. From the looks of it, there's areas in other cities & urban areas as well that the highway parallel an interstate for at least 5-10 miles.

Western US 2

With the exception of a 3 mile overlap with I-90 in Spokane, that would work. Still within the criteria as it follows an interstate for less than 5-10 miles.

[NE2]

US 17 and US 64.

[csw]

I'm gonna go with US 68. For running through a region with a lot of interstates, it stays away from most of them.

[Beltway]

US 17

Briefly overlapping I-95?
. . . . .

US-360

[sprjus4]

US 17 and US 64.

US-17 has a concurrency with I-64, I-95 and I-140 and runs parallel to I-95 for a significant distance in Georgia and Florida, also parallel to I-4 in Florida. Once the Kinston Bypass is constructed and I-42 is brought over to New Bern, US-17 would also overlap 7 miles of that. Unless of course the northern portion of the US-17 relocation is ever built.

US-64 has a concurrency with I-87, I-440, I-40, I-55, I-35, and runs parallel to I-75 and I-40 in parts.

US 101 does not parallel I-5.  By definition, parallel lines never meet but these two routes connect on 101's north end (Olympia WA) and south end (Los Angeles CA).

US-64 has a concurrency with I-87, I-440, I-40, I-55, I-35, and runs parallel to I-75 and I-40 in parts.

It also has a short concurrency with I-75 northeast of Chattanooga, with I-24 for about 25 miles northwest of Chattanooga, and with I-25 for a few miles in Raton NM.

US 101 does not parallel I-5.  By definition, parallel lines never meet but these two routes connect on 101's north end (Olympia WA) and south end (Los Angeles CA).

I think it's safe to say US-101 is an independent route. It does not really parallel any interstate highways directly and has no concurrencies as far as I'm aware.

[Max Rockatansky]

US 163 and US 550 come to mind. 

[Flint1979]

I'm sure that a lot of 3-di's will appear and it seems that most 2-di's do parallel an Interstate. Perhaps that's how the Interstate system was planned but I'm not sure on that.

US-127 and as mentioned earlier US-131 don't really parallel any Interstate's.

US-2 doesn't really parallel an Interstate either, it has no junctions with any east-west Interstate.

Concurrencies usually occur on routes that, in the big picture, head in different directions and serve different corridors. Thus, routes like US 64 that have many concurrencies are better examples than routes like US 101. The fact that a variety of concurrencies exist proves that there isn't a parallel interstate.

Personal opinion here, but 3dis do not count as parallel interstates, especially when looking at the entire length of the US route.

US 101 does not parallel I-5.  By definition, parallel lines never meet but these two routes connect on 101's north end (Olympia WA) and south end (Los Angeles CA).

Let's be realistic regarding our interpretations of "parallel". US 11 and I-81 cross each other many, many times, yet it cannot be argued that they aren't parallel - they are, full stop. Same with I-5 and US 101. For the most part, they run parallel to each other; whether US 101 counts for the thread is an open question only because of the distance from I-5, not because it's unclear whether they're parallel.

Most 3-di US routes don't parallel Interstate routes, or at least were not supplanted by interstates.  The ones that come to mind in my part of the country include 231, 280, 331, 411, and 431 in Alabama, 129, 319 and 341 in Georgia....

VA US-211

[Kulerage]

Are we allowed to post highways that used to parallel one, but have had their paralleled segments removed?

As long as it still does not follow it's parallel / concurrency path with an interstate highway today, then it's fine.

[hotdogPi]

US 113, which might be the only US route that doesn't even get near an Interstate.

In that case;

US 521 doesn't have any interstate that truly follows it's path.
US 701
US 73
US 400
US 199

[US 89]

US 113, which might be the only US route that doesn't even get near an Interstate.

US 163 begs to differ.
