Trying to compile a list of all the exits that have numbers in the U.S. (maybe Canada too). In your state, which non-interstate highways have exit numbers?
I'll start.
Colorado
CO21
CO470
E-470
Northwest Parkway
Pennsylvania
PA 43 (PTC portion)
PA 66 (PTC portion)
PA 576
PA 581
I am unsure if the Nanticoke Freeway on the northern section of PA 29 and the PA 309 freeway section north of I-81/PA 115 in Wilkes-Barre count. I see those as similar to the odd ADHS Corridor exit numbers on US 23 (Corridor B) and US 460 (Corridor Q).
The ones for US 15 and US 220 do not count IMO as they are intended for Future I-99.
Everything in Massachusetts has exit numbers besides MA 57, MA 28 on Cape Cod, US 1 north of Boston, US 44 in Plymouth, and MA 79
In California, all state-maintained freeways (many of them non-Interstates) have exit numbers. There are a lot of them. For some routes, some numbers are assigned but not posted, as reflected in the following list.
https://dot.ca.gov/programs/safety-programs/exit
In Alaska, funny thing is that, AFAIK, only its one non-Interstate freeway, the Johansen Expressway in Fairbanks, has exit numbers. Just a few, with low numbers. There are freeways with paper Interstate designations, but AFAIK no exit numbers.
All of Hawaii's freeways are Interstates, except a short HI 78 stub between HI 99 and H-201 that has no numbered exits of its own.
IL 255
IL 390
IL 6
That is off the top of my head for Illinois
For Maryland:
US 15 (9-18, Frederick area only)
US 29 (13-25, Howard County portion)
US 50 (3-45, includes unsigned I-595 overlap [7-24] but also extends further on either side)
US 301 (13-45, on portion overlapped with US 50)
US 340 (9-12, on portion overlapped with US 15)
MD 32 (3-25, freeway portion)
MD 100 (1-20, entire length)
MD 200 (3-20, entire length)
Michigan:
US-10
US-23
US-31
US-127
US-131
M-5 (east-west portion)
M-6
M-10
M-14
M-39
M-53
M-59
Essentially, all freeways in Michigan except:
M-5 (north-south portion)
M-8
M-47 (freeway portion)
M-60 (freeway portion)
I-375

No, not that. But you guys know I'm a nerd for tracking things and/or coming up with statistics. I thought it would be kinda cool to see which exit number is the lowest that doesn't exist, for example. Or how many Exit 0s there really are. Or what percentage of highways have an Exit 1, etc.

Interestingly, I think the only freeway in California without any exit numbering at all now is the short Route 33 spur in Ventura, at least as of 2020 when I and a friend took it as part of a roadtrip through Ojai.
Kentucky:
All the parkways
US 60 (Owensboro bypass)
KY 4 (New Circle Road in Lexington)
US 23 (Pikeville cut-thru)
KY 9007 (Has an Exit 0 at KY 622/Plano Road)
KY 841 (Gene Snyder Freeway between US 31W/60 and I-65)

Consider my shorts changed.
MN has a potpourri of partially completed ones with zero real coordination or planning
US 10 has a few one-offs through Blaine and Anoka
US 10/61 southeast of 494 have a couple one-offs
US 12 from I-394 to the western Hennepin CSAH 15 exit
US 14 on the recently completed four-lane in Dodge County
US 52 through South St. Paul, a few one-offs between the metro and Rochester, and then through Rochester itself (the latter was first non-Interstate in MN to get them)
US 169 on the Shakopee bypass up to the northern Hennepin CSAH 1 exit
US 212 between TH 62/US 169 and I-494
TH 62 Crosstown from Shady Oak Road to I-35W, and then on the TH 55 duplex
TH 77 south of the Minnesota River
TH 100, northern half
TH 610, the only complete one that I am aware of

That question came up here a few years back and it was 511, for the US. (https://www.aaroads.com/forum/index.php?topic=27509.msg2527385#msg2527385) Likely higher including other countries with kilometer-based exits.

Fear not, Alabama has no exit numbers on any of its non-interstate grade separations. Did I miss anything?
AL 255 (Research Park Blvd) - no
AL 158 (Industrial Parkway) - no
AL 152 (North Boulevard) - no
US 31/280 (Red Mountain) - no

Indiana:
IN 912
US 31 - Kokomo Bypass, Plymouth-South Bend, Hamilton County, and SR 28 interchange in Tipton County
St. Joseph Valley Parkway (US 20/31) - added to the list in 2024
IN 265 (resigned as I-265)
I'm pretty sure the only non-interstates in Texas with exit numbers are US 59 in Shepherd, US 75, US 54, TX 375, and Spur 601. Essentially just El Paso District's highways and two logical continuations of interstate highways.

They are I-99 AFAIC, they just need the route marker at this point.

After the MUTCD made it a requirement (Section 2E.31 in the 2009 edition, Section 2E.22 in the current edition...use of the word "shall"), the impression I got from MnDOT is they're adding exit numbers as part of normal sign-replacement projects. But they're not going out of their way to add exit numbers just for the sake of adding exit numbers if the rest of the guide sign doesn't need replacing. This would certainly explain the hodgepodge implementation you mentioned.
As for Vermont, there are only 4 non-Interstate roads rhat could be considered freeways. 3 of the 4 have exit numbers (VT 279 being the exception). VT 289's exit numbers are mile-based, going off the original Circ plans (mile 0 was to be at I-89 in Williston). US 4 (W of Rutland) and US 7 (Bennington-East Dorset) have sequential exit numbers, but also have those "Milepoint signs" that have sprouted up on the Interstates.
Just about every freeway in Michigan does with a few exceptions.

Which is particularly weird, given that full sign replacements of these routes are either underway or recently concluded. It would have been an excellent opportunity to switch them over, and the fact that they have not leads me to doubt that VTrans intends to actually follow through on a proper conversion.
Excluding US 67, the Hot Springs Bypass and US 82/167 through El Dorado have numbered exits. I guess AR 151 in Miller County has exit 1, even though it's just a continuation from loop 151 in Texarkana.

US 82 through Grayson and Fannin County uses exit numbers, although they correspond to TxDOT mile logs and don't have a true zero basis.

Which I could understand that if they didn't repeatedly replace/add new signs without adding the exit numkers (US 169 inside 494/694 and in Elk River, TH 101 at CSAH 39/90th St across the river incidental to that 169 project being two of these). That was more why I said it seems kind of haphazard.
US 19 & 82 in Albany, GA. If it hasn't been mentioned before ( I'm sure Rothman will de facto moderate lol) has exit numbers numbers on the Liberty Expressway.
Niumpers? Crazy autocorrect creates its own word.
West Virginia
- US 22
- WV 43, except for unnumbered interchange at I-68
These are the only two non-Interstates that are full freeways in West Virginia. (WV 43 has a diamond interchange at I-68.)

IMO that section of US 6 fits under the odd sequential mileage provision I mentioned for PA 29 and PA 309.
PA 378 in Bethlehem counts, but those numbers I believe came from when the freeway portion was briefly I-378.

Bring up something interesting. I've always known that PA 378 had exit numbers and always knew US 22 at its northern end had none. Didn't put the two together until now. Now I see the inconsistency even know it's been always been like that.
Since you brought up defunct I-378, I now see how that came to be.
For Missouri:
I believe MO-364 and MO-370 are the only ones. MO-364 had new exit numbering for the MO-94 north exit when they put in ramps in at Heritage Crossing.

They should be interstates anyway.
Iowa pretty much has exit numbers on every freeway and at-grade divided road with one-off interchanges.
Doesn't look like anyone's attempted NY yet. Exit numbers on non-interstates are not the norm here, but there are some. All numbered sequentially to my knowledge:
- Palisades Interstate Pkwy
- NY 27 - Sunrise Hwy
- Several (most?) of the Long Island Parkways (Belt, Grand Central, Cross Island, Southern State, and possibly others)
- NY 17 (future I-86)
- NY 390, NY 481, NY 590, NY 690 (state route extensions of their respective interstates)
And probably a couple of others I'm missing.

Is there a 375 anywhere in the US? The thread you linked doesn't mention one, and JayhawkCO mentioned in the other thread that it's the lowest exit number that isn't used on an interstate. I tried to find a non-interstate Exit 375 but couldn't, but maybe I missed something.

Thanks for the corrections/additions. Why I thought NY 690 had numbers is beyond me, I guess I just lumped it in with its state route extension of Interstate counterparts.
In Northern Kentucky, the KY 9/AA Highway has a county-based exit number (14) at the US 27 interchange in Cold Spring. If overall mileage was used on KY 9 starting near Grayson, the exit number would be 107.
In Ohio, there are quite a few. US 35 from Xenia to Washington CH (48-85) and in Gallia County (160-173), OH 2 , OH 11, US 24, US 6 around Napoleon and Bowling Green (including the at-grade interchange with I-75—Exits 66A-B), US 20 on the Fremont bypass and at the OH 420 interchange area, US 30 around the Canton area, US 33 near Athens (which are no longer county-based but state-based), US 50/OH 32 at both US 33 interchanges around Athens, and a county-based exit number (17) on OH 32 at the OH 327/124 interchange east of Jackson. Also, the Norwood Lateral received sequential exit numbers (1-3). Most of these exit numbers have been posted within the last ten years.
I believe most non-interstate freeways in RI have exit numbers, with the exception of RI-138 in North Kingstown-Jamestown.

Pretty much all of US 33 east of Columbus has exit numbers except in Pomeroy (not sure about west of Columbus towards Marysville). Also US 23 north of Columbus, including the interchanges for downtown Delaware and all interchanges in the Marion area.
I don't believe any non-interstate freeways in South Carolina currently have exit numbers.
Tennessee is as follows:
TN 153
TN 155
TN 386

Now normally Tennessee mileposts along all state highways are county-based, so exit numbers would end up resetting at county lines. Of the ones listed above, only TN 386 crosses a county line (from Davidson to Sumner), and the exit numbers and mileposts are all based on total mileage from I-65.

Maine has "lettered" exits on ME Route 703 (Maine Turnpike Approach) (https://www.aaroads.com/forum/index.php?topic=29087.0) and the freeway portion of US 1 between Brunswick and Bath (https://fox23maine.com/news/i-team/ask-the-i-team-why-are-some-route-1-exits-in-maine-now-using-letters-midocast-bath-brunswick-mainedot-road-changes-emergency-crews-first-responders). All of the ramps on these sections have "RAMP X" (where X is the letter) signs (https://www.google.com/maps/@43.6256653,-70.3283842,3a,44.9y,249.38h,88.09t/data=!3m6!1e1!3m4!1sfQKgxzq-_59DC8bZ5OfW3g!2e0!7i16384!8i8192?coh=205409&entry=ttu) when exiting or entering these segments. I don't think they are signed on ME Route 701, the Scarborough Connector as of now.
New Hampshire has sequential exit numbers on:
NH 16 / Spaulding Turnpike portion (Newington - Milton)
Everett Turnpike south of I-293/NH 101, on both segments where it's standalone and where US 3 is concurrent from Exit 7 to the MA/NH border
NH 101 between Exit 7 I-93 and Exeter Rd (Exit 13) - I-95 and I-93 (WB only) are unnumbered

Quote from: wriddle082 on June 11, 2024, 07:01:09 AMQuote from: amroad17 on June 11, 2024, 04:19:09 AMIn Northern Kentucky, the KY 9/AA Highway has a county-based exit number (14) at the US 27 interchange in Cold Spring. If overall mileage was used on KY 9 starting near Grayson, the exit number would be 107.
In Ohio, there are quite a few. US 35 from Xenia to Washington CH (48-85) and in Gallia County (160-173), OH 2 , OH 11, US 24, US 6 around Napoleon and Bowling Green (including the at-grade interchange with I-75—Exits 66A-B), US 20 on the Fremont bypass and at the OH 420 interchange area, US 30 around the Canton area, US 33 near Athens (which are no longer county-based but state-based), US 50/OH 32 at both US 33 interchanges around Athens, and a county-based exit number (17) on OH 32 at the OH 327/124 interchange east of Jackson. Also, the Norwood Lateral received sequential exit numbers (1-3). Most of these exit numbers have been posted within the last ten years.
Pretty much all of US 33 east of Columbus has exit numbers except in Pomeroy (not sure about west of Columbus towards Marysville). Also US 23 north of Columbus, including the interchanges for downtown Delaware and all interchanges in the Marion area.
I don't believe any non-interstate freeways in South Carolina currently have exit numbers.
Tennessee is as follows:
TN 153
TN 155
TN 386
US 25E in Morristown
US 27 in Downtown Chattanooga only (though technically this is unposted I-124)
Sam Cooper Blvd. (though these are old I-40 exit numbers back when... well, we all know how that went!

The exits along the freeway portions of TN 111 do not have exit numbers. The same is true for US 51 between Dyersburg and the Kentucky state line, or at least that was the case the last time I was on that road.
Connecticut, based on info from https://kurumi.com/roads/ct/exits.html :
Have exit numbers now:
US 7, CT 2, 2A, 3, 8, 9, 11, 15, 17, 25, 40, 66, 72, 182, 349, SR 571, 695, 796
No exit numbers now, but will soon with milepost renumbering:
US 6
Won't have numbers even after renumbering:
CT 20, 78, 187, 190, SR 598
All but CT 20 (Bradley Airport connector) are very short.
CT 34 used to have exit numbers but the short freeway now terminates in the New Haven street grid.
^ Adding exit numbers for 349 but not 20 strikes me as rather illogical.
The interstate-grade portions of US-69 in Oklahoma has exit numbers
In Virginia:
Richmond-Petersburg Turnpike had exit numbers before it was designated as I-85 and I-95 (this lasted for only a month)
The Virginia Beach Expressway (former VA 44) had exit numbers before it was redesignated as an extension of I-264
Lynchburg Expressway (US 29 Business and US 501)
US 19 in Lebanon
US 58 ALT in Big Stone Gap
US 58 ALT in Norton
US 58 ALT in Coeburn
US 460 in Christiansburg and Blacksburg
US 460 in Bluefield
US 460 in Tazewell
US 460 in Cedar Bluff and Richlands
VA 168 - the Hanbury Road exit northbound is accidentally posted without an exit number but all other exits are numbered
VA 267 - both the Dulles Toll Road and the Dulles Greenway
VA 895 has exactly one numbered exit - exit 3, for VA 281. By extension, VA 150 is a non-interstate freeway with numbered exits as VA 150 and VA 895 have combined mileposts
I think that's all of them. The routes listed multiple times all have different sets of sequential exit numbers that are unrelated to one another.

What interchanges on non-interstates here in Wisconsin don't now have numbers?

Quote from: JayhawkCO on June 06, 2024, 01:59:27 PMTrying to compile a list of all the exits that have numbers in the U.S. (maybe Canada too). In your state, which non-interstate highways have exit numbers?
I'll start.
Colorado
CO21
CO470
E-470
Northwest Parkway
And CO58
All of them. We don't have Interstates in Québec, despite FritzOwl's best efforts. :bigass:
I'll count non-Autoroutes.
- QC 112/116 has them on their freeway segment.
- QC 117 has exit numbers that are an extension of A-15's.
- QC 132 has them on its freeway segment in Boucherville.
- I'm not gonna acknowledge A-720, it's obviously still an Autoroute.
- QC 138 has them on the freeway that leads to Pont Honoré-Mercier.
- QC 175 has them for the QC 136 and Chemin Saint-Louis exits north of the Pont de Québec.
- QC 185 has had a numbered exit or two between the two A-85 segments, but I'm not sure if those became A-85 already.
^ At least Québec has an interstate-like autoroute system (even if there are examples like A-955), something no other province can truly claim to have. British Columbia, Alberta, Saskatchawan, and Newfoundland make no attempt to differentiate their freeways (and only Alberta has what I would consider to be a freeway system, though British Columbia would too if a couple key gaps were filled in). Manitoba and PEI don't even have any freeways that travel a significant distance (although maybe someday the Winnipeg beltway will be a full freeway; I'm not sure if PEI has any plans to upgrade more of TCH 1). Ontario has a reserved set of numbers, but uses the same shield. New Brunswick and Nova Scotia in theory have a separate shield, but both systems have tons of sections with at-grades and sometimes even driveways too; many of these will likely get upgraded over the long term, but both have routes I expect have no plans to ever upgrade (like NB 3, NB 4, NS 107, NS 142, and NS 162).
Quote from: LilianaUwU on June 15, 2024, 09:02:35 PM- QC 117 has exit numbers that are an extension of A-15's.
These are interesting, since A-15's mileage and QC 117's mileage are approximately the same. I wonder if that's why A-15's exit numbers reset and were never changed to reflect the entire route.
Quote from: LilianaUwU on June 15, 2024, 09:02:35 PM- QC 175 has them for the QC 136 and Chemin Saint-Louis exits north of the Pont de Québec.
Also for a short bit past the northern end of A-73, continuing A-73's exit numbers. But that's probably just MTQ preferring to end A-73 at a numbered route instead of a park.

And PEI's closest example, the Cornwall bypass of TCH 1, is still a super two.
Quote from: vdeane on June 11, 2024, 08:45:54 PM^ Adding exit numbers for 349 but not 20 strikes me as rather illogical.
In the same vein, there's an Exit 1 on CT 82 WB at CT 9 (which I guess makes 82 a freeway :-)

Ohio:

OH 2
In Nevada, US 95 still qualifies because I-11 has yet to be extended to Exit 99. CC 215 has exit numbers that continue I-215's numbering scheme. Of course, both of these are intended to become Interstates at some point.
One example that currently is
not planned to become an Interstate is NV 613 (Summerlin Parkway). It received exit numbers, including an Exit 0, recently enough that GSV has yet to capture them.

And Summerlin Pkwy, last I was on it, only had exit numbers on its western half, due to a recent construction project on that end replacing signs.
Only non-interstate freeway up in Northern Nevada is US 395, which has exit numbers—there is a jump in exit numbers crossing I-80 due to the section south of 80 being concurrent with I-580.
