Non-Interstate Highways with Numbered Exits

[TEG24601]

In Washington, non-Intersate Freeways/Highways don't have exit numbers.  However, I was just going over things I had, and remembered that the Sunset Freeway (US 26) West of Portland, OR, and OR 217 do have numbered Exits, as does Michigan and California.  Is this wide spread and Washington is odd, or vice-versa?

Numbered exits on non-Interstates are usually not a thing out here. NJ 42 and DE 1 are exceptions. The Garden State Parkway and the NJ Turnpike I guess qualify as well.

Numbered exits on non-Interstates seem not at all unusual; that might be something where states go both ways. UT 67, and the freeway segment at the west end of CA 299 as well as most of CA 99, come quickly to mind.

In Alaska, the only numbered exits in the entire state are on a road (Johansen Expressway in Fairbanks) that not only isn't an Interstate, it doesn't even have a signed state route number.

Pennsylvania does in some cases, but not universally.

For example, none of US 15's freeway sections (except the short I-180 overlap in Williamsport) have exit numbers, whereas the US 6 freeway northeast of Scranton does have numbered exits–even though that segment is numbered sequentially and mileposted without regard to its mileage throughout the rest of the state.

The US 220 freeway between Mill Hall and Linden is now signed with exit numbers which are mileage-based and continue where I-99's interchange numbers would resume assuming an overlap with I-80. And yet, where I-99 is slated to continue along the US 15 freeway north of Williamsport, exits are not numbered, even though some guide signs have blank exit tabs and space for a three-digit exit number to be added.

PA 33, which is a freeway from end to end, does not have exit numbers, while the exits on the freeway portion of PA 28 do, albeit sequential ones.

Interestingly, PennDOT only includes Interstate exit numbers on its official state map. Even if non-Interstates' exits are numbered, they're not shown.

Wisconsin regularly does this for non-Interstate freeways and expressways.

Georgia does this for GA 400 and US 78, but kept sequential numbering for them.

[NE2]

The latest MUTCD says it should be done. Florida does it on most toll roads but not free roads.

SR 3 and SR 16 have some numbered exits: https://www.google.com/maps/@47.545657,-122.673847,3a,26.3y,30.58h,96.99t/data=!3m6!1e1!3m4!1smp4TkZyqjLHG-vXKK4J0CA!2e0!7i13312!8i6656

Many freeways outside the US 

Seriously though, FL 528 has numbered exits when I went there in 2008/9.

[hotdogPi]

These all do:

MA 2
US 3
MA 3
NH 16
MA 24
MA 25
NH 101
MA 128
MA 140
MA 213
Everett Turnpike

It's actually unusual for a numbered highway with several exits not to have numbered exits.

Freeways or other interchanges without exit numbers:

MA 125 at MA 28 (single interchange, neither road is a freeway)
US 4 at NH 155A, 155, and 108 (expressway, not freeway)
MA 57 (legitimate example)
MA 116 (single interchange)
Plimoth Plantation Highway (unnumbered route)
Storrow Drive / Soldiers Field Road (unnumbered route)
Bypass of Keene, NH

1, you beat me to the punch.

Here's a few from MA you missed:

US 6/Mid-Cape Highway
Freeway portions of MA 146 (added within the last few years)
Lowell Connector

For NH, don't forget the Spaulding Turnpike.

A more challenging topic would be what Interstates have no exit numbers?

[Rothman]

Most NY parkways have numbered exits.

[roadman]

The freeway/expressway section of US 1 between the Tobin Bridge and the Danvers/Topsfield line doesn't have exit numbers.

[1995hoo]

From my observations over the years, the use of exit numbers on such roads is not at all uncommon, but it seems to be most common when the whole road is "freeway" grade. Virginia State Route 267, the Dulles Toll Road and Greenway, is a good example–it's better than some Interstates I've driven and it has exit numbers. The Durham Freeway, NC-147, is another; I lived right by Exit 15A for three years. The Bee Line (FL-528) has been mentioned already. Then you have the Garden State Parkway as another example.

It seems to me to be less common–I deliberately do not say "uncommon" or "nonexistent"–when a road transitions, either permanently or back and forth, between "freeway" grade and some other class of road. (An example of a road that changes back and forth is US-29 in Virginia, which has "freeway" sections, "expressway" sections, urban and suburban arterial sections, and at least one two-lane road section through the Manassas Battlefield from the War Between the States, and nowhere does it have exit numbers that I can recall. BTW, I put "freeway" and "expressway" in quotation marks to denote the technical terms since those usages are uncommon here.) Of course, there are exceptions; I recall US-15/501 in Durham had exit numbers on the bypass segment near Duke University when I attended said school in the 1990s, though there were no exit numbers on either road beyond the ends of said segment (except the obvious exception of the I-85 concurrency). We can always find exceptions, so I'm not saying "it never happens" or the like.

Then you have some of Nova Scotia's 100-series highways. Some of the "exit" numbers on those are not what most of us would consider "exits" since they're at-grade intersections (Route 103 heading around from Yarmouth towards Lunenburg and Halifax is an example), though others are in fact interchanges.

Up until PennDOT converted to mileage-based exit numbering in 2001, I-180 lacked exit numbers.

I-180 was my hometown interstate as a very young child, and when I finally saw I-80 for the first time around age four and discovered that the exits had the added bonus of exit numbers, I immediately assumed that 2DIs had exit numbers while 3DIs lacked them. Of course I quickly learned otherwise once I got my first atlas.

As to why I-180's exits weren't numbered–I always assumed that PennDOT was waiting for the entire 80-to-80 loop (the Susquehanna Beltway–"the Beltway" , as locals still call it) to be completed first. Perhaps pressured by local leaders to get red and blue shields in Williamsport, PennDOT designated the half that was completed as I-180 in 1984, but the fact that they didn't bother numbering the exits at that time suggests that they still had some notion that the two gaps in the western half of the Susquehanna Beltway would be completed in the near future.

I-676 in PA and I would think a lot of 3di's would lack them. Are there any 2di's that do?

LA 3132 in Shreveport, LA.  US 167 in El Dorado, AR now that the super 2 has been converted to a 4 lane highway.

Kentucky does exit numbers on freeways that aren't interstate highways. as in the Parkway System (Which is the bulk of non-interstate freeways) and I've even seen an exit number on KY 9 which isn't even a freeway.

Numbered exits on non-Interstates are usually not a thing out here. NJ 42 and DE 1 are exceptions. The Garden State Parkway and the NJ Turnpike I guess qualify as well.

I was going to correct you, and assumed you were confusing 42 and 55... but Wikipedia says they added exit numbers to 42 in 2003, about a year or two after I last drove on it.  There's also NJ 18 with exit numbers.

US 29 Business freeway through Lynchburg along with US 501 continuing the freeway has sequential exit numbers.

Some bypasses in southwestern Virginia have them, notably Christiansburg/Blacksburg...

The only ones I can think of are extremely short 3DIs in urban cores–like I-676 in Philadelphia, I-579 in Pittsburgh, I-175 and I-375 in St. Petersburg, and I-375 in Detroit.

what Interstates have no exit numbers?

I know two of Virginia's shortest Interstates, I-195 and I-564, do not have exit numbers.  However, Virginia's shortest Interstate, I-381, has one numbered exit (Exit 0) and two lettered exits (exit A for I-81 North, and exit B for I-81 South).

FL 408

US 50 in Maryland

This will be a rather comprehensive list...

Michigan has done it on most if not all US-route freeways, and on M-14 as well.  Google also shows exit numbers on M-6 south of Grand Rapids.

[The High Plains Traveler]

Starting to pop up in Colorado. Exits have been numbered on the E-470 tollway probably since it opened (Mile 0 at I-25 on the south end, not surprisingly). Recently, they have shown up on CO-115 where it has a few interchanges leaving Colorado Springs to the south, and on CO-21, Powers Blvd., in its brief freeway sections like at the Platte Avenue (U.S. 24) exit.

Minnesota, as far as I've seen, only has them on U.S. 52 in its freeway section through Rochester.

In New Mexico, U.S. 84-285 north of Santa Fe has them. U.S. 84 is treated as a north-south highway, and its mile 0 is where it intersects U.S. 60 at Fort Sumner and continues east to Texas concurrent with 60. The only other non-interstate freeway in the state is U.S. 70 east of Las Cruces, and when I last drove that highway it had no exit numbers.
