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.

It was supplanted by I-5 south of downtown Los Angeles.

US 141 south of metro Green Bay, WI was supplanted by I-43.

Historically it was, though the southern terminus has been since truncated at the I-5 / I-10 / CA-60 / US-101 interchange south of Downtown.

[dlsterner]

US 98 comes to mind.  I suppose you could quibble about a short parallel stretch with I-10 in Mobile, and a brief concurrency with I-59 near Jackson.

The I-10 segment could fall under the OP's allowance for a short stretch (and you can consider I-10 to be parallel with US 90 primarily).

The I-59 concurrency is very short between an east-west road and a north-south road, which nobody would consider I-59 and US 98 to "parallel" each other.

[sprjus4]

The I-10 segment could fall under the OP's allowance for a short stretch (and you can consider I-10 to be parallel with US 90 primarily).

I'd say it works mainly because it's a water crossing, and that's really the only feasible place for both routes to cross. The divert from each other immediately after crossing.

The I-59 concurrency is very short between an east-west road and a north-south road, which nobody would consider I-59 and US 98 to "parallel" each other.

It still is a concurrency nonetheless, but it is under 5-10 miles, so it would still work.

US-98 works.

US 8

I-35 and I-35W replaced it into Minneapolis, with a concurrency for a number of years before truncation to the current Forest Lake terminus.

US 53

Could argue that I-94 parallels it for an 18-mile stretch from Eau Claire to Osseo.

[jp the roadgeek]

US 44 really doesn't, thanks to the NIMBY's cancelling I-84 from Hartford to Providence.  One can argue that it parallels I-84 between the Middletown, NY area and Manchester, CT, but it's far enough away during most of the trek, even jogging northeast away from I-84 between Poughkeepsie and Canaan, CT.  US 6 is the true one that parallels 84.  Even east of Providence, it loosely parallels I-195, but diverts away more due east while I-195 deflect southeast.

US 4 east of Whitehall, NY doesn't parallel any interstate, nor do US 2 or US 302 between Montpelier, VT and Fairfield and Portland, ME, respectively. 

[mgk920]

US 53

Could argue that I-94 parallels it for an 18-mile stretch from Eau Claire to Osseo.

IMHO, I-94 was routed independently of US 53 and that 'parallel' part is just a co-incidence.

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.

That works now, but I-75 runs along the pre-truncated route of US-2 from (roughly) St Ignace to Sault Ste Marie.

[hbelkins]

I saw US 58 mentioned, which was the one that immediately came to my mind. It has a short concurrency between Bristol and Abingdon with I-81, but other than that, it's an independent route.

How about US 23? Its concurrency with I-26 is a relatively new thing.

Wouldn't US 27's current incarnation (terminating  at I-69 in Ft. Wayne) work? It's far enough away from I-75 in Ohio, Kentucky, Tennessee and Georgia to qualify.

Come to think of it, US 33 and US 35 work too, as does the current US 48.

[CNGL-Leudimin]

The Devil's highway, now known as US 491.

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

US 163 begs to differ.

As signed maybe, but officially it still runs all the way up to I-70 IIRC.

[Kulerage]

US 8

I-35 and I-35W replaced it into Minneapolis, with a concurrency for a number of years before truncation to the current Forest Lake terminus.

OP allows highways that used to, but no longer have parallel segments.

[sprjus4]

Debatable. While most of the route is independent, the overlap with I-81 is 20 miles, which exceeds the 5-10 mile limit. Also, in the future there will be more interstates being concurrent with US-58. 7 miles of I-785 and US-58 will be overlapped in Danville, along with 7 miles of I-73 in Martinsville if an eastern route is selected, though that'll most likely end up going west. Even if you pushed that aside though, Hampton Roads is where it's not an independent route. I-264 parallels US-58 for 25 miles, and for that stretch, US-58 is a local road, and I-264 is the main thru route.

So approximately 45 miles of interstate highway currently concurrent with US-58, and at least another 9 or so miles in the future.

[Takumi]

US 258 fits this.

[Max Rockatansky]

US 199 also fits the criteria. 

[webny99]

So approximately 45 miles of interstate highway currently concurrent with US-58, and at least another 9 or so miles in the future.

Why would that disqualify US 58, a 508 mile long route, as a whole? Most of it is independent and has not been supplanted by interstates. Totally opposite situation to I-81/ US 11; guess which one I'd pick as a contender if I had a choice?

IMHO, I-94 was routed independently of US 53 and that 'parallel' part is just a co-incidence.

Thank you! This is what I've been saying. The I-94 example is irrelevant in the context of US 53 as a whole. How can you say US 53 from Duluth to Eau Claire doesn't qualify just because of a glitch south of Eau Claire?

The entire point was to identify U.S. Highways that do not parallel or have a concurrency with an interstate throughout it's entire duration -at all- or minimal such as a 3-5 mile overlap traversing through a town or something - like US-2 and I-90 through Spokane.

If the overlap with I-81 was only 5-10 miles long, and I-264 wasn't intentionally built parallel to US-58 for almost 30 miles to supplement it in Hampton Roads, then that'd be a different story.

[webny99]

I get that. All I'm saying is if you ranked all US highways based on the percentage that has been supplanted, US 58 is going to be near the bottom. You might only find 5-10 US highways that have fewer concurrencies or parallels than US 58.

So even if US 58 is not a technically correct answer, it is closer to being a correct answer than the vast, vast majority of other US highways. Unlike US 11, it still serves an important purpose for long distance traffic for much of its length. Thus, I think US 58 does fit the spirit of the thread (although obviously that isn't my call  ).

I get what you're saying, and the thread may well evolve that way. I think we've hit most of the highways that follow the original topic, so I guess this is the direction it will go, or else the thread will die. But obviously, something like US-11 is out the door instantly.

[Roadsguy]

Here are the ones that enter PA:

• US 219
• Western US 422
• US 222 (it parallels I-78 for the last 14 miles, but they go off in different directions)
• Arguably US 209 (It briefly parallels a few Interstates and even runs concurrent with I-80 through Stroudsburg, but quickly diverges on its own path each time.)

Alt. US-58 takes US-58 away from any I-81 concurrency at Abingdon and doesn't rejoin US-58 until Jonesville.

However, I argued elsewhere that Alt. US-58 is conceptually more like a US-458 or US-658 than any actual part of the US-58 route.

When I was considering US-58 for this thread, the obvious objection was I-264 between Bowers Hill and the VA Beach oceanfront.

[Revive 755]

US 65

Overlaps I-530 from the Little Rock area down to Pine Bluff.

US 75

Debatable given the proximity to I-29 between Nebraska City and Sioux City.

[sprjus4]

If we're going to be a little more flexible, then US-158 could work.

It's mostly an independent routing, and only encounters and follows a few interstates for a short distance -
- Parallels I-85 for about 12 miles near Henderson, NC
- Parallels I-40 for about 16 miles southwest of Winston-Salem.

In the future, the US-158 relocation & widening project currently underway near Roanoke Rapids will re-route US-158 and overlap I-95 for 3 miles. Also, once I-87 is completed in northeastern NC, there will be a 3 mile concurrency northwest of Elizabeth City.

In total, once I-87 is completed & the US-158 re-routing over I-95 is completed, the 347 mile route would only parallel & overlap 34 miles of interstate highway, or 9.7% of the total route.

Since we're being a little more flexible now with the main no-interstate-whatsoever routes out of the way, it could work. Only 8.8% of the total routing follows or overlaps interstate highways.

See my new edit to the original post that now qualifies any route that follows less than 15% of interstate highways.
