Border-to-border state highways

[Max Rockatansky]

Hypothetical question...what about border-to-border state highways that no longer exist from renumbering and states that never had on to begin with?  If we're counting anything that might have existed I'm fairly certain there are several in the old Nevada State Highway route log that would qualify.  I couldn't ever find a border-to-border state highway that ever existed in Arizona.

Also if we're counting water as a border than CA 299 might qualify for the sake of this discussion terminating a mile or two of water at US 101 and the Nevada state line at old NV8A.  CA 78 is really, really close to both the AZ state line in Blythe and the coast at I-5 in Oceanside.

Also...I need some input from a Utah expect since I know there is a signage gap but what about UT 30?  I'm fairly it exists technically on I-84 and I-15.

FL SR 10 goes from a couple blocks from ocean in Atlantic Beach/Neptune Beach to AL state line west of Pensacola.. although it is subservient to US 90 for most of the route

There is a two-fold problem with counting Florida State Routes as border-to-border.  First; there is coastline on three of the state's borders.  Secondly almost all the major state routes are mostly just hidden designations for US or Interstate highways.  You could say that FL 8 and FL 5 reach border-to-border as well simply because I-10 and US 1 run from the state line to close an ultimate terminus point near a coast or on one.  FL 50 probably would have been coast-to-coast to example of a stand alone state route before it was truncated from Bayport to US 19. I guess FL 60 kind of counts since it ends at Clearwater Beach and A1A in Vero Beach. 

If you count only land borders with other states, I believe Florida's only qualifier is the eastern segment of SR 2, which turns into GA 94 on both ends.

I'll have to look in a minute after lunch but I just thought of GA 121 crossing from Florida to South Carolina.

Edit:  You're right about FL 2 in the Okefenokee Swamp but GA 94 technically is also Florida Border-to-Florida Border as well since it looks like it continues east of St. George to CR 2 on the Florida side.

CT has a few N/S that don't qualify because of water (8, 10, 12, 32, plus 104, 123, 124, 137 in the SW corner), but CT 41 runs from the NY border to the MA border (and beyond) in the NW hills of Litchfield County.  The only RI route that qualifies is 138 from the CT to MA border.  MA includes the same CT water border routes above (which qualify in MA), plus MA 31.  If you count silent concurrencies with US 1, MA 1A does.  NY 17 used to qualify when it ran from the PA border to the NJ border (excluding the Waverly dip).

NY 17 still counts. It still goes all the way.

You mean like Illinois 8, that basically followed the routes of US-34, current IL-8, and US-24 across the entire state before the US routes came along?

Yes routes like that...another example being Nevada State Route 1.  It could be just even run of the mill state highways that were decomissioned or renumbered over time into multiple routes.

What about all the unsigned state routes in Alabama and Georgia that go from border to border by running concurrent on US Highways? Do they count?

I tend to view them as the same as the hidden designations in Florida hence why I picked GA 121 since it's part of a three state route. 

Okay what about a segment of the good old proposed US 789 with WY 789 since it crosses from Montana to Colorado border-to-border.

[Duke87]

I'm surprised that these are the only ones in Iowa. Even more surprising to me is that there are only 2 "legitimate" examples in my eyes (165 is in Carter Lake, the community west of the Missouri River near Omaha; 27 is just the number they slapped onto the Avenue of the Saints corridor, where all but 10 miles are concurrent with a different route).

Indeed, a lot of the examples in the TM list end at the same border twice (e.g. IA 165) or exist in a corner of a state and end at two perpendicular borders (e.g. CT 41). Routes which legitimately span the entire width or height of a state and end a two opposing borders are less common. Topologically speaking even OK 3 doesn't technically qualify for that on account of it originating at the border with CO rather than NM.

The fact that OK 3 is entirely redundant with various US highways west of Watonga also makes me turn a hairy eyeball at it, though I suppose we have US 412's creaton to blame for that.

The only state highway that goes border to border in Wisconsin is Wis 32 and that was purposely made to travel border to border to honor the 32nd Red Arrow Division.  There is a long concurrency with US 45 to the Michigan State Line just for that honor.  Wis 35, Wis 64, Wis 70, and Wis 77 fall short just shy of the 2nd border.

Can we count route 9 in Maine, New Hampshire and Vermont?

[jp the roadgeek]

Can we count route 9 in Maine, New Hampshire and Vermont?

Sure.  And add Routes 11, 12, 25, 26, 119, and 123 in NH, and (for all intents and purposes) 11 in ME.  If you really want to get technical, add ME 113 (twice) and ME 113B in NH

[kurumi]

My first thought was that this has to be a pretty big list, so rather than listing a few examples I could come up with, I decided to run a search through the Travel Mapping data for routes in state highway systems that have first and last waypoints of the form "XX/XX", which is what we would normally use to denote state boundaries.  Here's what I got.  Note that it includes highways that border Canada where the province postal abbreviation was used, and excludes anything that uses a non-standard border waypoint label.

Also MN 23 in the Superior area.

What about all the unsigned state routes in Alabama and Georgia that go from border to border by running concurrent on US Highways? Do they count?

They're fully signed in Georgia, so I would argue that they count. Alabama, Florida, and Tennessee, not so much.

AL-10 goes from Mississippi to Georgia with only the section from Luverne to Brundidge concurrent with US-331, US-29, and US-231.
There's also AL-117 which goes from Tennessee to Georgia in the northeast corner with only a couple hundred feet on US-11.

The "Georgia" example is literally ridiculous. I've actually been there and I remember this sign. I still find it funny that there are so many highways running concurrently in that one spot. I also remember some pointless turn lanes along there that went no where but into the swamps.

FL SR 10 goes from a couple blocks from ocean in Atlantic Beach/Neptune Beach to AL state line west of Pensacola.. although it is subservient to US 90 for most of the route

There is a two-fold problem with counting Florida State Routes as border-to-border.  First; there is coastline on three of the state's borders.  Secondly almost all the major state routes are mostly just hidden designations for US or Interstate highways.  You could say that FL 8 and FL 5 reach border-to-border as well simply because I-10 and US 1 run from the state line to close an ultimate terminus point near a coast or on one.  FL 50 probably would have been coast-to-coast to example of a stand alone state route before it was truncated from Bayport to US 19. I guess FL 60 kind of counts since it ends at Clearwater Beach and A1A in Vero Beach. 

If you count only land borders with other states, I believe Florida's only qualifier is the eastern segment of SR 2, which turns into GA 94 on both ends.

SR 2 in Florida becomes SR 91 at the Chattahoochee River crossing. I've driven that route to Donalsonville way too many times. If we're including heavily multiplexed roads, AL 53 would qualify; it starts at the Florida border with SR 71 near Malone, heads toward Dothan and you don't see it again as a standalone until you get to Huntsville, where it becomes TN 7.

[Darkchylde]

I checked Louisiana, and it has zero examples due to having rivers on the western border and both eastern borders, as well as the Gulf on the south. About the closest thing it has to a border to border highway that isn't an Interstate or US highway is LA 1, which starts at a dead end literally feet from the Gulf, and runs north and west to near the Ark-La-Tex tripoint.

Hypothetical question...what about border-to-border state highways that no longer exist from renumbering and states that never had on to begin with?  If we're counting anything that might have existed I'm fairly certain there are several in the old Nevada State Highway route log that would qualify.  I couldn't ever find a border-to-border state highway that ever existed in Arizona.

Yes routes like that...another example being Nevada State Route 1.  It could be just even run of the mill state highways that were decomissioned or renumbered over time into multiple routes.

Nevada has no current examples, due to no state route overlaps and state route numbers being assigned mostly by county clustering.


In the pre-1976 numbering, there only two border-to-border examples that come to mind:

• State Route 1 (later US 40, now the I-80 corridor): CA to UT
  
• State Route 6 (later US 91, now the I-15 corridor): CA to AZ - although this one is border-to-border, it only clips the southern tip of the state.
  Another one you could potentially count was State Route 3, which went on a circuitous ~330-mile route from CA (via US 50 at Lake Tahoe) through west-central Nevada back to CA (via today's SR 266).
  
  
  EDIT: Realized 10 days later that I didn't complete my thought...added in SR 6.

I would also include AL 9, which is a standalone highway from the Georgia border to Wetumpka.  Then it's absorbed into US 231 then US 331 down to the Florida line.  There is also WYO 789 from Colorado to Montana that is fully signed even along the US routes.

Too bad Florida is out due to it being surrounded by water on three sides

Too bad Florida is out due to it being surrounded by water on three sides

There could be one that goes east/west from the Alabama border to the Georgia border.

[roadman65]

The segment of FL 2 between the two GA segments of GA 94 I guess  it could really count.
