Which Non-Interstates In Your State Have Exit Numbers?

[wriddle082]

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.

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!

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.

NJ Turnpike
Garden State Parkway
Atlantic City Expressway
Palisades Interstate Parkway
NJ 18 (only the southern portion)
NJ 21
NJ 24
NJ 138 (sort of, exits 35 and 36 are a continuation of I-195's numbering system)
NJ 42
NJ 55

Maine has "lettered" exits on ME Route 703 (Maine Turnpike Approach) and the freeway portion of US 1 between Brunswick and Bath. All of the ramps on these sections have "RAMP X" (where X is the letter) signs 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

Forgot about the Atlantic City Brigantine Connector, which has lettered exits too (A, B, E, F, G, H, and I)

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.

[Streetman]

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.

[vdeane]

^ Adding exit numbers for 349 but not 20 strikes me as rather illogical.

[Robinsml]

The interstate-grade portions of US-69 in Oklahoma has exit numbers

[WillWeaverRVA]

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.

[Dirt Roads]

North Carolina:

Surprisingly, the two "unnnumbered" freeways (Raleigh's Wade Avenue and Greensboro's Bryan Boulevard) do not have any exit numbers (except the I-73 portion of Bryan Boulevard).

I highly suspect that there are more in North Carolina.

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

Mike

[jlam]

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

And CO58

[LilianaUwU]

All of them. We don't have Interstates in Québec, despite FritzOwl's best efforts. 

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.

[vdeane]

^ 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).

- 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.

- 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.

I wonder if MTQ eventually plans to upgrade QC 175 further north. Work's already almost done.

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).

And PEI's closest example, the Cornwall bypass of TCH 1, is still a super two.

[kurumi]

^ 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 :-)

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

For Green Bay area: WI 54 Mason St Bridge, WI 54/57, WI 172, US 141 north of Abrams.

Niumpers? Crazy autocorrect creates its own word.

Somehow, I feel compelled to give this weird misspelling a definition.

niumpers (noun), plural - figures or amounts one quickly makes up without a second thought (note: not to be confused with imaginary numbers).

[tigerwings]

Ohio:

US 24
US 23 has exit 234 signed before the MI line
OH 2

[Scott5114]

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.

Any examples up north?

The interstate-grade portions of US-69 in Oklahoma has exit numbers

Other Oklahoma non-interstates with exit numbers:
- OK 351 (Muskogee Turnpike portions)
- OK 364 (eastmost portion)
- OK 375 (Indian Nation Turnpike)
- US 412 (Cimarron and Cherokee turnpike portions)

[thspfc]

Wisconsin
US 10, 12, 14, 41, 45, 51, 53, 61, 151
WI 16, 26, 29, 64, 145, 441

Does US-61 have its own numbers anywhere? Should be on 151's in Grant County.

[Interstatefan78]

For NJ these are
RT-21 Newark to Paterson
RT-18 Old Bridge to Point Pleasant
RT-55
RT-42
These are none Interstate State highway freeways to have an exit number
NJTA
GSP parts are US-9
NJ Turnpike Exits 1-6 since 6-73 are I-95 Mainline NJ Turnpike followed by Exits 14A-C I-78

[amroad17]

Ohio:

US 24
US 23 has exit 234 signed before the MI line
OH 2

Also, US 33 from St. Mary's (OH 29 interchange) to I-75 in Wapakoneta (25-38) as well as OH 126 and OH 129.

US 33 does have state mileage-based exit numbers on the freeway portion between Bellefonte and Dublin.

Any examples up north?

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.
