Which Non-Interstates In Your State Have Exit Numbers?

[formulanone]

Jayhawk's scared of formulanone breathing down his back in the lowest exit thread...

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
US 31 (scattered along Montgomery Highway) - no
US 82 (McFarland Boulevard) - no
US 43 (scattered here and there) - no

You forgot Memorial Parkway!
US 231/US 431 (partially) (Memorial Parkway) - no

Duh. I forget it has exits at all, it's mostly mini-Texas slip ramps.

The ones for US 15 and US 220 do not count IMO as they are intended for Future I-99.

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

MN has a potpourri of partially completed ones with zero real coordination or planning

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.

[Flint1979]

Just about every freeway in Michigan does with a few exceptions.

[vdeane]

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.

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.

[TBKS1]

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.

[Road Hog]

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.

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.

[roadman65]

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.)

[hotdogPi]

WV 9? US 250 south of Wheeling?

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.

Also, the PA-28 freeway from it southern terminus (on the Northside of Pittsburgh) to US-422 - though these are sequentially numbered exits

Also...US 6 Casey Highway in Lackawanna County (sequentially numbered).  And maybe PA 378 in Bethlehem?

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.

[cenlaroads]

In Louisiana:

The freeway portions of US 90
LA 3132 in Shreveport

These are the only ones I'm aware of.

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.

[froggie]

These are the only two non-Interstates that are full freeways in West Virginia.

WV 9? US 250 south of Wheeling?

Pretty sure he was referring to routes that are freeway for their entire length within the state (hence the cliffnote he added to WV 43).

They should be interstates anyway.

[SSOWorld]

Iowa pretty much has exit numbers on every freeway and at-grade divided road with one-off interchanges.

[webny99]

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.

NY 890 is mile-based, as are the the Taconic and Hutch.  NY 481 is due to switch.  NY 690 doesn't presently have exit numbers.

[TheCatalyst31]

...which exit number is the lowest that doesn't exist, for example.

That question came up here a few years back and it was 511, for the US. Likely higher including other countries with kilometer-based exits.

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.

[webny99]

 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.

[Ted$8roadFan]

I believe most non-interstate freeways in RI have exit numbers, with the exception of RI-138 in North Kingstown-Jamestown.
