State Highways in your state that are exclusively freeways

[OCGuy81]

What are the state highways in your state that exist for their entire length as freeways? 

For example, I'm in Oregon, and this is an easy one.

- OR-217 is a freeway its entire length.

MA 24

MA 25

MA 213

Forgot about the surface part of 128 in Gloucester.

IN 641 is exclusively freeway.

IN 265 (which goes away as soon as INDOT gets around to signing it as I-265) is exclusively freeway.

IN 912 is almost exclusively freeway, but it extends a bit south of I-80/94 as a surface street.

Washington:

SR 512
SR 518 (though it ends at a signalized interchange)
SR 520
SR 599

And some almost freeways:

SR 8 - still a divided highway with only a few interchanges
SR 16 - Northern terminus isn't grade separated
SR 18 - Tiger Mountain section is being upgraded, Federal Way stub is going to still be a city street
SR 167 - Still being upgraded, but will have a short stub in Renton as well
SR 509 - Will be moved to a freeway in phases

That's a fairly lengthy list for California.  Rather than list them all, I'll just point out the most obscure in the form of CA 77 and move on.

Just LA 3132 for Louisiana

The only ones I can think of in PA at the moment are PA 33 (though ends at an intersection with PA 611), PA 581, PA 283 (has two stoplights on it now at its western end, one for the I-76 access), PA 43, and PA 576.

[GaryV]

M-6
M-14 (although there may be some unsigned old parts of it that are not freeway, but still on the state books)

[OCGuy81]

Took a stab at Wisconsin, having recently visited family back there.

WI-119 Airport Spur

WI-30 in Madison

WI-441 in Appleton

[jlam]

Just CO 58 and CO 470 in Colorado. CO 21 might be added in the future.

I think VA-267 is a complete freeway.
Old VA-44 was one, until it got replaced by I-264.
VA-164 and VA-195 are freeways, VA-195 is an extension of I-195.

For VA, I think you are only missing VA 288.  I cannot fully justify VA 37 due to having stoplights at the I-81 ramps and an at-grade with SR 642 at its south end.

[TheHighwayMan3561]

MN:

TH 77 (some might dispute this based on whether they believe 77 ends at the McAndrews Road interchange or at the 138th St intersection)
TH 100
TH 65's unsigned south segment from 35W/94 to downtown Minneapolis
TH 280 (northbound only)
TH 610

100% my fault, I only had the ones I listed at the top of my head. I was about to publish an edited version with VA-895. Still forgot about VA-288.

Georgia

* all SR route numbers 401 - 411
* SR 413, 415, 417, 419, 421
* SR 10 Loop (also numbered 422)

Most of these are state route numbers for Interstate routes, except for 410 and 422/10 Loop . 410 has US 78 overlapping it, and people usually just call it 78 and not 410. Similarly, 422 is never called 422 but rather 10 Loop. It also has US route overlaps (with 78 being one of those routes) but there are sections without any overlaps.

So it could be argued that if Georgia didn't use SR numbers for Interstates/US routes, 10 Loop would be the only exclusively-freeway route. But on the other hand, it might be instead numbered US 29 Loop/Alternate/etc .

[jmacswimmer]

I think the only 2 in Maryland are MD 10 & MD 200, although both have a signalized intersection at one of their termini.  Two other close contenders:

-MD 100: Has 2 signalized intersections in the final mile before its eastern terminus at MD 177
-MD 295: Although mostly unsigned, it officially continues past the north end of the B-W Parkway along Russell St and the Greene/Paca one-way pair to a northern terminus at US 40

After a quick scan, it appears Florida only has State Road 9B South of Jacksonville, which is supposed to become I-795. State Road 202 (Butler Blvd) in Jacksonville almost makes the cut, but has a very short at-grade section from Phillips Highway to I-95.

The state has plenty of toll roads designated as state roads, but no other all-freeway state routes to my knowledge.

[kirbykart]

For NY we have:

- NY 400: A freeway from West Seneca to East Aurora (Buffalo metro)

- NY 695: A short connector in the Syracuse metro.

That's all I can think of right now but there are probably some others.

[Quillz]

CA-55
CA-57
CA-22
CA-52
CA-56

There are more, I just thought of these off-hand. Also they might technically have some non-freeway segments, but usually they are just glorified off-ramps (like with CA-22).

That's a fairly lengthy list for California.  Rather than list them all, I'll just point out the most obscure in the form of CA 77 and move on.

I thought it might be a longer list than this, but there's a number of routes that have short non-freeway sections on one end or the other (CA-55, CA-237, etc.)

SR 11 — Otay Mesa*
SR 15 — San Diego
SR 24 — Oakland to Walnut Creek
SR 51 — (unsigned) Sacramento
SR 52 — La Jolla to Santee
SR 56 — Del Mar to Poway
SR 57 — Santa Ana to Glendora
SR 60 — Los Angeles to Beaumont*
SR 71 — Corona to San Dimas*
SR 73 — Mission Viejo to Costa Mesa (toll)
SR 77 — Oakland**
SR 85 — San Jose to Mountain View
SR 87 — San Jose
SR 110 — North Hollywood to Pasadena
SR 125 — Otay Mesa to Santee
SR 134 — Los Angeles to Pasadena
SR 163 — San Diego to Miramar
SR 170 — North Hollywood to Sun Valley
SR 210 — Glendora to Redlands
SR 217 — UC Santa Barbara to Goleta
SR 241 — Rancho Santa Margarita to Anaheim
SR 242 — Concord
SR 244 — Carmichael**
SR 259 — San Bernardino
SR 261 — Irvine to Orange
SR 905 — San Ysidro to Otay Mesa

*Very nearly almost all freeway, actively removing non-freeway portion
**Stub

[Max Rockatansky]

Depending on how you view CA 15 that is also entirely freeway nowadays.  Unless I'm mistaken doesn't CA 163 technically end before it becomes a surface highway?

Yeah, by the legal definition you're correct. For both of those I was thinking of the stub/ramps south of I-5. Added to my list.

[Ted$8roadFan]

The only ones in RI that comes to mind is RI-24 and RI-99.

[froggie]

MN:

TH 77 (some might dispute this based on whether they believe 77 ends at the McAndrews Road interchange or at the 138th St intersection)
TH 100
TH 65's unsigned south segment from 35W/94 to downtown Minneapolis
TH 280 (northbound only)
TH 610

Two "formers" worth mentioning:  MN 103 (Lafayette Freeway extension south of I-494, now US 52) and MN 312 (now US 212 in Chanhassen & Eden Prairie).

In my other "states of interest":

None in Alabama (AL 255 comes close but has at-grades before its northern end).

The only one in Mississippi is MS 304.

Only VT 279 in Vermont.  VT 289 is debatable because it has a jughandle about a mile north of VT 117 (which was intended for a side road that was never built).

[ilpt4u]

IL 6 and IL 255 are the two that come to mind in the Prairie State, and both for the same reason: State route continuation of Interstates 474 and 255, respectively

The IL 390 Elgin-O'Hare Tollway also fits
