Like a I-x0/x0, or I-x5/x5, or I-x0/x5 or US x1/x1, you get the idea

I-80 and I-90 through half of OH and almost all of IN. In fact I-80 is useless in IN, as it overlaps other interstates all the way through the state.
Supporter of the construction of several running gags, including I-366 with a speed limit of 85 mph (137 km/h) and the Hypotenuse.

Please note that I may mention "invalid" FM channels, i.e. ending in an even number or down to 87.5. These are valid in Europe.

Not a whole lot of them for Interstates. This list may be exhaustive:

-I-90/I-15 in Butte
-I-15/I-80 in Salt Lake City
-I-70/I-35 in Kansas City
-I-10/I-45 in Houston
-I-10/I-35 in San Antonio
-35/40 in Oklahoma City
-I-20/I-55 in Jackson
-40/55 in Memphis
-55/70 in St Louis
-40/65 in Nashville
-40/75 in Knoxville
-I-75/I-85 in Atlanta
-I-80/90 in Indiana and Ohio
-40/85 in North Carolina
-65/70 in Indianapolis

I think they meant the 0s and 5s, but I hesitate to call I-45 "major".

If one were to depart from the idiom of nothing but "0" and "5" Interstates as "main" routes and used traffic and connectivity as criteria, it would be safe to say that the following routes could be considered "main":  for N-S routes, 29, 59, 81, and 87 (the real one in NY, not the pretender down south); for E-W routes, 44, 64, the western 84, and 94 (funny how the 4's take up the slack for the 0's).  49 will certainly join the list when complete -- and possibly 69 well into the future.  Because of truck traffic, I'd almost put 57 on the list; but in reality it functions more as a "55E".

Given all that, concurrencies of 35 & 44, 44 & 55, 55 & 64, 64 & 75, 64 & 81, 64 & 95, 29 & 35, 29 & 80, 20 & 59, 90 & 94 (multiple), 15 & 84, and -- later on -- 44 & 49, would fill out this collection. 

Just think of it as a paraphrase of the immortal words of Jessica Rabbit:  "I'm a non-quintile divisible Interstate -- I'm not bad, I was just drawn this way!"

I'd probably put I-24 on your travel corridor list, also, but not sure if I call it North/South or East/West...

And one could argue that I-64 and I-44 could be unified under a single number -- I think I've seen that argument around these parts before. I-60 or I-50 would be appropriate, I think, but it violates the (old) Interstate and US route duplication rule/guideline

That being said, some more concurrencies...mostly IL-centric:
US 51 in IL...Is concurrent with:
US 60, crossing the Ohio near Cairo, IL
US 50, in Sandoval, IL
US 40, in Vandalia, IL
I-55, around Bloomington/Normal, IL
US 20, around southern Rockford until Cherry Valley, IL
I-90, near Cherry Valley, IL, around Rockford, to the Wisconsin border
As an aside, US 51 crosses US 30 in IL also, but neither the I-39/US 51 freeway nor Old US 51/current IL 251 run concurrent with US 30

Others I can think of, across the state of IL:
US 20 and US 41 on the South Side of Chicago, leading to Gary, IN
US 40 and I-70 crossing the Wabash River on the IL/IN border, near Terre Haute, IN, and between Pocahontas and Highland, IL, and then joining I-55/I-70 heading towards the Mississippi River and STL

In the nearby category:
US 41 joins I-80 (and I-94) just across the border from IL in NW IN, between Calumet Ave and Indianapolis Blvd
US 31 and US 20, around South Bend, IN
US 41 and US 50 (and US 150) around Vincennes, IN
US 61 and I-55, near Cape Girardeau, MO
US 50 and US 61 in STL
US 40 and US 61 (and I-64) west of STL into Wentzville
US 61 joins I-80 in the Quad Cities/Davenport, IA area
And of course, in Indy, US 31 and US 40 are concurrent on I-465, somewhere...

Is New York's I-87 really a main route? Sure, it has high traffic counts but that measure is pretty biased towards a place like New York City. I-87's high traffic volumes are on the Thruway section that connects New York and Albany. North of Albany and it's pretty desolate.

I'm not ready to call a road that generates most of its traffic by connecting New York's largest city with its capital a "main route." In my opinion, no intrastate interstate highway can be a "main route."

It connects the 2nd and 8th largest cities in North America and provides part of the New York City truck bypass. If it weren't for the international border, it would be a continuous designation. I'd say I-87 warrants "main route" more than I-45 or I-30. And if you're going to bring traffic counts into this, the least-trafficked 2DI is I-95 in Maine. Just sayin'.

I didn't know that. My experience in Tennessee (well non-interstate anyway) is mostly Memphis & Chattanooga. I remember seeing bi-directional arrows but not the N-S or E-W

Someone beat me to US 11 and US 41 in Chattanooga, but there's a short concurrency of US 11 and US 21 in Wytheville, Va.

Also, US 31 and US 41 in Nashville. Add bonus, US 31A and US 41A.

US 60 and US 21 had a historical one between Chimney Corner and Charleston in WV. US 60 has concurrencies with US 31E, US 31W, Alternate US 41 and US 51 in Kentucky.


Government would be tolerable if not for politicians and bureaucrats.

US 89

US 30 and 91 in Pocatello, ID.

Historically, US 91 and 40 in SLC, and US 91 and 50 in central Utah.

Also, do x5's count for major US highways? Routes like 75, 85, and 95 seem pretty important.

Some US x5's were quite important -- but only in regards to particular segments.  5 was important as the major N-S "inland" route in New England.  25 was pretty important north of Greenville, SC (at least to Detroit).  45 from Fulton, KY north to Kankakee, IL was important as well, as was 65 north of Des Moines.  75 was important from its historical southern terminus at Galveston north to Tulsa, a bit less important from Tulsa to Sioux City, and secondary north from there.  85 was a bit bifurcated -- quite important from El Paso to Denver, less so north of there.  95 had one important stretch:  Las Vegas to (historically) US 30 in SW Idaho; the rest was only locally useful -- except for its northernmost section from Coeur d'Alene north to the Canadian border.  Nationally, 15 & 35 didn't really register, although from its multiplex with US 11 north to (historically) Rochester 15 had some regional significance.  And until Ohio elected to improve 35, it was really no more than a regional anomaly.

There's the current version of the US 20/US 71 concurrency  in the Early and Sac City area of Iowa, as opposed to the original version which went through Early. There's also the US 30/US 71 concurrency near DeWitt.

Not quite - I-80 is alone on the ramps between the Indiana Toll Road and the Borman Expressway

And as I stated in other thread, any route that is either just a ramp, unsigned or concurrent with other route is useless for me. So I-80 is totally useless in IN, as it is just a ramp when alone. I would end I-80 at I-294 in IL, and make the section East of Elyria OH into an Eastern I-82 :bigass:. Another option would be rerouting I-80 into the planned Illiana, along US 30, and I-71 and I-76 back to its present route, but that is fictional terrain.

Fictional, yes, but a lot of US 30 east of Fort Worth is already Interstate-grade or close to it. Carry on...

Funnily coincidental that I-30 is (more or less) interstate grade east of Fort Worth.

I-80 and I-90 through half of OH and almost all of IN. In fact I-80 is useless in IN, as it overlaps other interstates all the way through the state.
And I-80 splits from those overlaps on both sides. East of Cleveland and west of Chicago I-80 is by itself so is it suppose to be like I-76, I-84 and I-88 and have a gap in the middle of its route?

Flint1979

I-75/85 in Atlanta.
I-80/90 from about 40 miles west of Cleveland to Lake Station, Indiana.

Those are the only two that come to mind right now.
