State Suffixed Highways

[florida]

FL hates suffixed state routes  and only signs them when needed with the highest being SR 30E. There were quite a few "planned" ones that got up into the Gs, Hs, and Js (I believe.....will have to check the Bay County maps again). County roads are a different story as there are plenty of those, the highest being Dixie County 351U and Citrus County 44W (to not confuse with SR 44 in Crystal River).

I forgot to mention...OK-9 has three lettered spur routes. They are, in order: OK-9A, 9A, and 9A.

Huh?

[deathtopumpkins]

whaa?  3 routes with the same suffix?

New York, as mentioned earlier, uses suffixed routes.  US 9W is directional because it's west of the Hudson River.  Many suffixes use the letter A (I'd assume it's for "Alternate").  Some examples are NY 104A, NY 41A, NY 11A (from US 11), NY 38A, NY 15A and NY 96A.  Other letters are used, such as NY 34B.  The most suffixed routes I'm aware of are US 9 (thanks to an earlier post), and NY 31.  The following is a list of suffixed routes of NY 31:

Former:

• NY 31B
• NY 31C (replaced by NY 317)
• NY 31D

Current:

• NY 31A
• NY 31E
• NY 31F

Arkansas has used several different suffixes.  A (Alternate) (historical), B (Business), C (City) (historical), E (East), S (Spur), T (Truck), W (West), and the enigmatic Y.  The Y routes comprise of the third leg of a "Y" intersection.  Some are regular spur routes, while some are exit ramps or the third leg of an Oklahoma Y.  Most of the Y routes are either unsigned or they are signed as one of the routes they connect to in one direction, and the other route in the opposite direction.  An example is AR 88Y in Mena.  It connects US 59/71 to AR 88 which meet in an Oklahoma Y, and is signed as US 59/71 NB and AR 88 SB.  Occasionally, one of these Y routes accidentally gets signed:

You sure eased a little of my confusion about AR's signage.   I saw, in Stuttgart, a US79C designation (I think, it's been a few years).  I do remember doing a double-take when I saw it.  As far as I know, LA doesn't suffix ANY routes.  We only have 1 alternate state route (LA 2), and all other business/spur routes have banners above the shields.

Tennessee has like three suffixed state highway.

I think 220A and maybe one other one.  TN does have a fondness for suffixed US highways.

While A = Alternate makes a lot of sense, I think it's equally likely that it's just coincidence, and A was chosen simply because it's the first letter of the alphabet. Then the next route gets B, the next gets C, etc. (Unlike Arkansas, where the letters do have a clearer meaning.)

Also, you missed 17, which had lots of former routes, and current routes lettered A, B, C, K, and M.

Nebraska used to have many at one time, but the only one still standing is N-25A, which connects US 6 in Palisade with N-25 north of town.  I'm not sure why this isn't a connecting link, which is Nebraska's own system of highways with suffixes.

Which isn't really so much suffixes as a different way to mark routes, lettered A through Z.  The number just stands for the county in which the link or spur exists.

Since this thread has already been raised from the dead, I'll join in.

Do the CONN routes in Michigan count?  Connectors M-13 and M-44.  It's more like a prefix than a suffix, or like a business route.  They're a couple leftovers from when freeways were built.

Nope, that's a bannered route.  Georgia has them too, I believe.

[dgolub]

A whole batch of people have mentioned New York, which has a ton of them.  Connecticut was also already mentioned, so I'll say Massachusetts, which has a few, such as MA 2A and MA 6A.

[MVHighways]

MA/NH 3A, MA/NH 1A, NH 111A, among others.

Edit: spelling fix, and Maine doesn't have a 1A that is a state route, but there are multiple US 1A segments within Maine.

What Tennessee suffixes, Kentucky banners (at least for xxA routes). US 41A becomes Alternate US 41 at the Kentucky state line.

Virginia has its Y routes, which are short spurs of existing routes, mostly used at triangle intersections.

Virginia once had VA 37E and VA 37W briefly in the early 1930s north out of Warsaw.  37E became part of VA 3 while 37W became part of VA 202 (now secondary).

Some of the Texas park roads have suffixes.  All roads in state parks are maintained by TxDOT, but some of them are designated state highways, as Park Road X.  I believe park roads are a subcategory of the loop/spur system, which is a division of the State Highway system (I mean "State Highway" system as opposed to US Highway or Interstate Highway or Farm to Market Road systems).  Each system and subsystem has its own set of numbers.  Some of the park roads have branches, as needed to cover the park, and some of them are suffixed.  "A" is the only suffix that I know of being used.  They are shown on the statewide planning map, and are referred to in minute orders, but are not listed in the designation files.

Business routes, all of which are state highways regardless of the parent route's system, are technically suffixed, in alphabetical order, so that each "Business US X" is unique (as Business US XA).  I think the signs are supposed to have the letter in small print below the number, but that frequently isn't done.  I don't know if this meets the intent of the topic, but it's a possibility.

Arizona:

AZ 89a (formally US 89A) AZ89 @ Prescott to Business I-40/Historical US66 @ Flagstaff

AZ 95s (Signed as AZ 95truck) Parker (To CA 62)

AZ 180a The southern terminus of the highway is located at a junction with SR 61 near the community of Concho. It heads northerly from this intersection to its northern terminus at a junction with US 180 northwest of St. Johns
AZ 180a does dot return to parent.

Hawaii has on Maui 32A, 32B, and 36A. All are short spur routes to harbor and airport facilities.

I'm pretty sure Georgia doesn't currently have any of these, but it used to.

Current GA 85 Alt through Warm Springs used to be GA 85W, while current 85 through Manchester was 85E. This was changed sometime around 1996.

Current GA 3 (also US 41) from midtown Atlanta up through Marietta used to be GA 3E. The other branch (Marietta Blvd/Atlanta Rd) was not GA 3W, however; it was just plain 3. Around 1986, 3E was renumbered to 3; the old 3 shows up on GDOT maps as GA 755 (which probably wouldn't have been signed) before being fully decommissioned around 1990.

I'd argue the Ss are just spurs, since they are sometimes signed as spur, but if we're counting them then:



Though 266 Spur is just signed as "spur"

I guess I should've been a bit more specific. Are there other "directional" suffixed state highways? N,S,E,W that are split alignments of one highway?

Arkansas has a 58E (which used to be US 62/63) but no 58W.  AR 1 used to split into 1E and 1W at Paragould.  There is also an unsigned AR 23W in Madison County, but no 23E.

And now 23W is signed:

whaa?  3 routes with the same suffix?

Because ODOT.
