Are there any Interstates that are completely duplexed/multiplexed with another route besides the following:
-- I-277 in Akron is completely duplexed and signed with US-224 on its entire route.
-- I-465 and I-469 in Indiana are both multiplexed with at least one other US along their alignments (though not signed as such).
Sure
I-180 Wyoming
I-115 Montana
I-315 Montana
I-515 Nevada
I-182 Washington
I-190 So Dakota
I-194 No Dakota
I-180 Nebraska
I-135 Kansas
I-444 Oklahoma
I-240 Oklahoma
I-790 (NY 5/8/12) and I-587 (NY 28)
Also I-99 (US 220)
I-73 ( I-74/US 220/US 421/I 840 Future) until the next extension north of Greensboro, which will be just I 73.
I-894 in Wisconsin is multiplied with I-43 or US45 it's entire route. By the end of this year, it will multiplex with I-41 for it's entire route.
All interstate highways in Georgia are (unsigned) multiplexed with 400-499 numbers, so:
I-16 (GA-404)
I-285 (GA-407)
I-475 (GA-408)
I-185 (GA-411)
I-675 (GA-413)
I-575 (GA-417)
I-985 (GA-419)
and I-516 (GA-421)
I think I-195 Florida is also FL 112, though not signed as such. Also, I-585 South Carolina, with US 176, and the new I-495 North Carolina (both full and future segments), with US 64, as well as I-140 North Carolina, with US 17.
And I-265 in Kentucky, with KY 841, and unsigned I-296 in Michigan, with US 131. There are probably a bunch of others.
The unsigned paper Interstates of Alaska and Puerto Rico are each completely multiplexed with one or more signed state/equivalent routes.
I-376 in Pennsylvania used to be entirely multiplexed with US-22 until I-376 was extended in 2009.
I-581 with US 220 (Roanoke, VA)

Name an Interstate in Florida that isn't "multiplexed" with another route (They have hidden state routes following each one - same for Georgia)
Even if we limit it to routes that are actually signed, Georgia still has a couple:
- I-516 is concurrent with SR 21 for its entire length
- I-575 is concurrent with SR 5 for its entire length
In the "close but no cigar" category, US 23 hops onto I-985 for all but the southernmost four miles.
Another "almost" one... I-39 has US 51, I-90, or I-94 for all but the 8 miles north of where it leaves I-90/94.

<Tangent>
Personally, I wouldn't mind a non-concurrency between US-41 and I-41...as in, US-41 "turns into" I-41. I really wished this was how the entire 2di aspect of the Interstate system was applied (3dis would be as they are today so long as numbers are available by state).
</Tangent>
Back to the topic at hand, I-270 in Colorado has this distinction, running concurrent with US-36. That said, unless something has changed...US-36 isn't signed along this stretch.
I-535 (MN/WI) is entirely combined with US 53.
Also, besides US 51 hopping off of I-39 a few interchanges north of its south end at I-55 in Normal, IL, I-39 is all by its lonesome between I-90/94 (Cascade Interchange) and where US 51 hops on on the north side of Portage, WI. That part of the freeway was WI 78 before it was 'promoted' into a full interstate back in the 1980s.

Actually, what you'll find is that, unless Congressional action dictates otherwise, FHWA rulings *DO* carry the force of law. But since we're talking about US routes, FHWA doesn't get involved with their routings. That's strictly between AASHTO and the states.
With the move of US 24 to go around the north side of Fort Wayne instead of the south side, I-469 is now independent between where US 33 leaves and where US 30 joins. Only a few miles (exits 11 to 18) but it is now independent of US routes for a short stretch whereas it used to always be combined with 33, 24, or 30.
I-305 and MD I-595. Both are signed as, and run entirely concurrent with, US 50 AFAIK.

It ends at I-80 according to the mileposts and FHWA.
Even if it did end at the first at-grade west of 80, I-88 would still be completely multiplexed with a state route. IL-92 follows the John Deere Expressway (IL-5/I-88) all the way from the 1st Avenue interchange in Silvis to Exit 6 (Joslin).
I-25 is so close, especially for a major 2di. Colorado Springs disqualifies it, though.

305 is an interesting case as later FHWA route logs suggest that it would include a section of freeway not part of US 50, but unsigned Route 51 (between US 50/Route 99 and E Street) that was built as I-80/US 99E in the 1960s.
Essentially, Business 80 paralleling 29th and 30th Streets has a concurrency with TWO unsigned routes!
The only other California all-concurrency interstates:
One existed briefly in the 1960s and was likely never signed: I-105 along US 101 on the Santa Ana Freeway between I-5 and the San Bernardino Freeway (today's US 101 exit 1D).
The other: the 1974-1982 I-15E with unsigned state route 194. (Whole thing, which was US 395, is now I-215)
http://socalregion.com/highways/socal_unsigned/foothill_fwy/
I noticed that I-210 according to a 1971 map is entire route co-signed with CA-118 prior to an updated version of Foothill Freeway in Pasadena.
For a brief time in the 60s, I think all of I-271 was also OH 1.

CA-51 Elvas/ Marconi Freeway/East Cap city Freeway. was co-signed with I-80 prior to 1980. Since 1980 it has been known as Business 80.
Incorrect.
Route 51 was created in 1982 as an inventory number (unsigned) for Business 80. Prior to that, the entire road WAS I-80 alone (1968-1981) or I-80/US 99E (1965-1967), and before that, US 99E in its entirety and US 40 from Arden Way northeastward.
The original Route 51 in the 1964 route renumbering was a former alignment of US 101 near Angel Stadium that was deleted from the system a year or two later.

Yes, but there's I-74 also, so I-465 is only overlap-free from interchange 16 to interchange 25. Still, that seems to disqualify I-465.
But this brings to attention I-865, with US 52. Has that been mentioned yet?

Exemptions can be (and are often) requested, subject to engineering study. Bottom line is that FHWA has final approval over any design aspect on the Interstate system. But, as it has been since the beginning, they leave actual construction to the states.
QuoteBetter yet, how was the Woodrow Wilson Bridge replacement allowed to still be a draw span when ruling prohibits such things on the system?
FHWA does not explicitly prohibit drawbridges on the Interstate system. It highly discourages them, but they are not explicitly prohibited, as there are certain situations where a fixed-span may not be possible (I-264 VA and I-110 MS are examples).
I-129 is entirely multiplexed with US 20 and US 75.
I-380 in Iowa is multiplexed with IA 27 and US 218 (its northern end).

Heck look at NJ 24 which was truncated back to Hanover, NJ when the long awaited freeway completed in 92. There are still NJ 24 shields to this day along the former route west of Morristown and it has been over twenty years since NJ 24 ended in Hackettstown.

Actually there is about a 9-mile stretch of I-465 that is not multiplexed with any other highway between exit 16 (I-74) and exit 25 (I-865/US-52). That makes up for the mile and a half on which there are 7 other highways unsigned with it between exit 46 and 47.

U.S. 20-26-87 also parallel I-25 for a short distance east of Casper, WY. 85-87 may also go through Walsenburg, CO (seems to me AASHTO says so), but that route is only marked BL I-25.

I-580 in the Bay Area was once multiplexed with I-5w and US-50 prior to 1964. This was before West end US-50 was moved to the I-305 West Cap city freeway location in Sacramento.
Again, no. 580 and 505 were replacement designations for 5W, they never existed at the same time. (And US 50's west end did not extend to the WX Freeway/Business 80 routing until after 1982; from 1968 to then it was at I-80/Route 99.)

How about I-180 in California it was entirely a temporary Designation that was entirely on the former north end of CA-17 before it was known as I-580 Richmond-San Rafael Bridge. CA-180 is in Fresno area.
The proposed 180 was never intended to be signed along with Route 17, but rather a replacement designation (as the eventual 580 extension is).
I-359 in Alabama is multiplexed with AL 69 and US 11 for all of its 2.76 miles, and it has a wrong-way multiplex to boot.
Business I-40 in Winston-Salem, NC is entirely duplexed with US 421, and Business I-85 in Greensboro is multiplexed with US 29 and US 70.
Yes, I realize that these aren't full-fledged interstate routes, but these are two of the four most likely "green routes" to receive a full interstate designation, in which case they would qualify for this thread.
I am old enough to have traveled on Business 40 through W-S and Business 85 through Greensboro when those routes were the mainline interstates, before they were bypassed.
In Florida, every interstate and US highway is entirely concurrent with an unsigned state highway.

Surprised Nevada's 580 (concurrent with US 395 in its entirety) hasn't been given a mention yet.
I-515 (I-11) concurrent with US 93 & Us 95

The I-11 routing has not yet been decided to take over for I-515. It may go an entirely different direction through/around Las Vegas.

I-73 ( I-74/US 220/US 421/I 840 Future) until the next extension north of Greensboro, which will be just I 73.
At least until I-73 hooks up with US 220 again near Summerfield.. The only portion of I-73 that will be without any concurrences is the one between I-840 future near the airport and US 220 north of Summerfield.

Business I-40 in Winston-Salem, NC is entirely duplexed with US 421, and Business I-85 in Greensboro is multiplexed with US 29 and US 70.
Yes, I realize that these aren't full-fledged interstate routes, but these are two of the four most likely "green routes" to receive a full interstate designation, in which case they would qualify for this thread.
Business I-85 in Greensboro is multiplexed with US 29/70 only till the US 29 exit (Exit 223 of I-40). East of that, Green 85 is multiplexed with I-40. However, that may change as US 70 is proposed to stay with I-40/Business I-85 til the Future I-840/785 (Exit 227) exit then follow the loop back to the original routing of US 70-Burlington Rd. (Exit 19 of Future I-840/I-785).
However, yes they are multiplexed the entire way if you mention the route between Lexington and Greensboro

What about the segment that will enter SC south of I-74/US-74 in Rockingham? I haven't heard anything about that being possibly multiplexed.
I don't know, but I don't think the future segment between I-74/Us 74 and the SC border will be multiplexed with any route unless it is changed.
Did anyone mention I-516 in Georgia?

I-535 (MN/WI) is entirely combined with US 53.
Also, besides US 51 hopping off of I-39 a few interchanges north of its south end at I-55 in Normal, IL, I-39 is all by its lonesome between I-90/94 (Cascade Interchange) and where US 51 hops on on the north side of Portage, WI. That part of the freeway was WI 78 before it was 'promoted' into a full interstate back in the 1980s.

US-51 stays on I-39 and joins I-55 SB around B-N. BUSN 51 goes through town on the old route. Thus all of I-39 is concurrent with another route (US-51 and/or I-90)

You're correct on I-39/US 51 near Bloomington, IL. But Mike's also referring to Wisconsin, where I-39 is "alone" for a few miles immediately north of where it splits off I-90/94 near Portage, WI.
I-190 in Rapid City, SD is totally concurrent with US 16.
I-180 in Cheyenne, WY is concurrent with a whole handful of US Routes and even BL I-25.

Isn't all of I-49 in Missouri cosigned with US-71? If so, I hope 71 is moved back onto its old route at some point.
The old alignment has been obliterated in places and in other places is just a frontage road. There are very few segments of old 71 that don't closely follow the 71/49 freeway.

The big question is when the Bella Vista Bypass is completed will US 71 still be routed through Bella Vista and Pineville, or will both MO and AR have AASHTO move it onto the new freeway?
US 71 will stay on the highway through Bella Vista. There is no question of this, unless AHTD changes their policy. I would like to see US 71 (and US 62 where appropriate) returned to US 71B through Fayetteville/Springdale/Lowell/Rogers/Bentonville. The northern and southern parts of the original Fayetteville loop can become x49s or US 71S and 71Y.
Agreed there. That is why it is so great they gave the Future I-49 in Miller County an AR designation instead of moving US 71 on to it. Even though not allowing I-49 to be on it was for other reasons it worked out that they did invent a state route number so that US 71 stays where its at.
The route south of Texarkana is not "Future I-49", it is AR 549. It will one day be I-49 (probably within the next year) but it is not signed "Future I-49" and is not known as such.
I did not mean "Future I-49" as being its official route number. I meant it literally as it will be future I-49 as in someday when LA and AR connect the the two freeways. I believe I said it was AR 549 and complimented AHD for thinking of that one in the same manner as DelDOT did by giving the St. George Canal Bridge in Delaware a "BYPASS US 13 designation before the DE 1 Turnpike was finished. Now US 13 could remain its original alignment through St. George, DE instead of designating it another road to go back later.
