States That Have 2 Or More State Routes With The Same Numbers

[cpzilliacus]

Virginia has/had several VA route extensions of US routes but VDOT considers them a single route.

SR 211?  Though GSV shows at least one U.S. 211 assembly west of I-81.

Yes...

The current pairs are US 33/VA 33, US 211/VA 211, and US 360/VA 360.  There are error US 33 and US 211 shields on the state route portions.  VA 211 is a late-comer to this dynamic, as VA 260 used to be the designation from VA 42 to New Market.  It is unclear why west of I-81 was renumbered to VA 211 when there is zero possibility of it ever becoming US 211.  VDOT tried to get a US 360 ALT designation for current VA 360 when it was created in 1982.  Not sure why they didn't call the route VA 360 ALT.
The complete list of pairs, past and present:

US 13/VA 13 (VA 13 was south of the Chesapeake Bay for a time)
US 17/VA 17 (VA 17 upgraded to US 17)
US 29/VA 29 (VA 29 was an alternate routing for US 29 from Culpeper to Warrenton.  Southern half is now VA 229, northern half no longer primary)
US 33/VA 33
US 121/VA 121 (this is current VA 121; US 121 renumbered as US 52)
US 158/VA 158 (both renumbered to 258)
US 211/VA 211
US 258/VA 258 (most of VA 258 became US 258)
US 301/VA 301 (VA 301 became US 301)
US 311/VA 311
US 340/VA 340 (VA 340 became VA 12 but later became US 340)
US 360/VA 360
US 501/VA 501 (VA 501 became VA 39 in the 1940 state line renumbering)
US 522 was a renumbering of VA 522 but both were not present in Virginia at any one time

Indiana has several: 8, 37, 39, 43, 45, 48, and 71 come to mind immediately.  Some of these may have "implied" connections -- 43 and 45 with US 231, along separate segments; 37 along its previous alignment multiplexed with IN 9 and US 24, and 71 as being partially subsumed by the IN 63 expressway.  Also some, like 8, occupy much the same trajectory, just without connection between sections.  I suppose the hard mileage cap within IN has a lot to do with the numerous gaps.

That's IN for you.  IN 4 may or may not be a broken route with three segments.  Or it's three separate routes.  Who knows?  IN 25 exists west of US 231 and east of I-65.  Maybe it exists in the middle.  Or maybe not and it's just US 52.  IN 26 got cut in half the same way IN 25 did.  There's no trying to make sense of it.

[vdeane]

Can't believe I forgot NY 878.

[hotdogPi]

New Hampshire has three routes numbered 111A. I'm not sure why this is, since they have many other routes with both an A and a B, so they easily could have done 111A, 111B, and 111C.

With all that I am surprised you never mentioned VA 42 which is in I believe 3 parts.

[Mapmikey]

With all that I am surprised you never mentioned VA 42 which is in I believe 3 parts.

VDOT conceptually considers this as one continuous route - traffic logs show the multiplexes required with the primary routes to make it so.

SR 615 between New Castle and US 220 is not particularly bad and could probably be put into the primary system without a ton of work.  SR 730 OTOH between VA 100 and US 460 is terrible.

If VDOT is never going to connect them up (SR 730 was removed as VA 42 but the other current gap has mostly always been secondary) after 80+ years, they should renumber the southern extension as part of VA 91 and the middle section as part of VA 18.

[jp the roadgeek]

I thought this was 2 state routes.  If we're going multiple numbers of different type of routes, NY currently has more:

Unrelated
NY 2 and US 2
NY 15 and US 15 (questionable with creation of I-99)
NY 78 and I-78
NY 81 and I-81
NY 86 and I-86
NY 88 and I-88
NY 90 and I-90
NY 95 and I-95
NY 190 and I-190
NY 278 and I-278
NY 290 and I-290
NY 295 and I-295
NY 695 and I-695
NY 990L and I-990

And then there's the state routes that are (mostly) continuations of 3DI's: 390, 481, 495, 590, 690, 787, 878 (though I-878 is unsigned), 890

Pretty famous, and mentioned in threads elsewhere on this site, but Maryland has a state route 68, and I-68 in the same county with interchanges on the same freeway (I-70, exit 18 and exit 1A, respectively). There are signs (here and here) on westbound I-70 approaching Exit 18 to inform and warn drivers that MD-68 is not the same as I-68.

Curiously, I am not aware of any similar signs on I-70 eastbound coming out of Pennsylvania.

Similarly, and I guess less famously, there is an I-97 (Anne Arundel County) and Md. 97 (Montgomery County and north).  Similar in the sense that the state highway came before the Interstate highway.

They are far enough away from one another that there is no real confusion.

[TheHighwayMan3561]

I thought this was 2 state routes.

Me too. In that case Minnesota has three US/MN duplicates all related to each other:

US/MN 61 (MN 61 replaced decommissioned US 61 northeast of Duluth)
US/MN 169 (extension of US 169 from Virginia to Ely)
US/MN 65 (extension of US 65 from Minneapolis to Littlefork; MN 65 existed on its route long before US 65 was decommissioned between Albert Lea and Minneapolis)

[Road Hog]

Arkansas:
45, 37, 74 (most frequent reused), 170, 253

Those are just off the top of my head.

AR 88 is another one. With the 2-digit highways, most of these disjointed segments are at least arranged where they could theoretically be connected. With 3-digit highways, who knows.

It even happens with 1-digit highways. AR 5 has a gap between Cabot (where it joins US 67) and Little Rock (where 5 resumes as Stagecoach Road). Theoretically 5 could be duplexed along with 67 and I-30 to Roosevelt Road and then down Asher Avenue. (Google Maps is incorrect; 5 doesn't pick up again until west of University.)

[mapman1071]

California has a ton of them borne out of incomplete/unbuilt routes, implied routes through National Parks, or relinquishment.  Really by technicality they aren't duplicates since they generally exist complete on paper in legislative definition but some of the notables would be; CA 39, CA 178, CA 190, CA 65, CA 120, CA 89, CA 146, CA 173, CA 169, and CA 146 just to name a few.  Florida has duplicates among US, Interstate, and State Highways but that is only because US in addition to Interstates also have state route numbers.  Some notable examples would be US 1/FL5 and FL A1A or I-10/FL 8 and US 90/FL 10.  Although the segments of FL 2 and FL A1A are more in line with what you asked for.  Arizona has some duplicates US and State highways; US 89, US 89A, AZ 89, AZ 89A in addition to my personal favorite come to mind:



In the case of AZ 95 things get even stranger since there is literally two different highways that carry that State Highway number.  The first segment runs from the Colorado River at the California State Line at Needles to AZ 68.  The second AZ 95 runs from I-40 to I-10.

AZ 95 South Section Ends At JCT US95/Business I-10 In Quartzite
AZ 95 North Section Ends At Nevada State Line/NV 163 on Colorado River Bridge (1/4 Mile W Of Jct AZ 68)


There is also AZ64 split by Grand Canyon National Park  South/North Signed I-40 to GCNP, East/West GCNP to US89 at Cameron.

Florida had quite a few CR segments that are in the grid.. Many used to be SRs or secondary SR

Many times thete is an unsigned and unacknowledged multiplex, usually only seen on old maps. The FL Atlas and Gazeteer will show even unigned segments of CRs.

Around me i can think of the following off the top of my head

SR 224 on Kingsley Ave And then CR 224 on College Dr in Clay County with implied multiplex with SR21

Multiple secions of CR 315 in Clay, Putnam an Marion Counties, with multiplexes with SR 16 and 21

CR225 loops around US301 in Clay, Bradford and Alachua Counties.

The routes are in the same general overall corridor but for the general non roadgeek public its confusing

There are tons of similar ones around Florida

-------------------
For states like FL, GA, MD and DE there is no rule against different "classes" of roads having same number... So SR 29 and US29 is ok... I like the FL state highway grid

Don't forget the two SR 931s, one near Kokomo and the other south of South Bend. We could argue that all of the following are duplicate routes, though some were once connected as continuous roads: SR 1, 3, 11, 22, 44, 63, 70, 101, 109, 110, 114, 119, 121, 144, 159, 218, 234, 236, 237, 250, 252, 335, 337, 545, and 550. If my count is right, that makes 36 different routes numbers that are duplicated. Some are used three or four times.

[Scott5114]

Oklahoma has several instances. Some were once one route and had a gap created in the middle (like 74 and 52), some were never connected but the routes are 'close enough' to get the same number (58), and some are two completely unrelated highways that have the same number, often because one connects to a route with the same number at a state line (4, 37).

[oscar]

Alaska has two disconnected AK 10 segments (Chitina and Cordova), and four AK 7 segments (Haines, Juneau, Petersburg, and Ketchikan). At least the AK 10 gap is due to a never-built connecting road between the segments. I'm not sure there ever was a plan to build a continuous AK 7 down the southeast panhandle, but if there was it probably died more than a half-century ago.

Hawaii has no route number duplication within the state system. However, there are duplicate numbers between the state and county systems, usually where a county route is or was intended to be an extension of a state route. County routes generally use route markers identical to state routes (until the late 1960s, both state and county routes were in a unified route numbering system), to further confuse the tourists.

[Bickendan]

Oregon has a good number of duplications between its Route (signed) and Highway (internal) systems, but that's largely irrelevant in affecting the general public. The Route system avoids duplication, with two exceptions:
I-82 and OR 82. It could be argued that they're related by a (non-existent) connection via I-84 between Hermiston and La Grande.
I-205 and OR 205.
The Oregon Transportation Commission considers neither of these are close enough to each other as to be confusing for the public.

Something I forgot about is gaps in state roads that were relinquished back to counties but are still signed as county routes.  A good example would be the gap in FL 15 from the 528 tollroad south to US 192/441/FL 15 with CR 15 on Narcoossee Road.  That situation certainly creates duplicates in many other locations that may not always be apparent due to the State Road number being silent on a US or Interstate Route.

[bzakharin]

One could argue that there are two NJ 41s; granted both segments are linked with sporadic TEMPORARY 41 route signage.

The temporary 41 is actually official NJ 41 at least internally. NJ 440 is sort of discontinuous (connected by NY 440), but the county route that it is concurrent with (CR 501) doesn't continue into New York under that number, so has a real discontinuity. Some of the 600 series county routes have sloppy definitions making them intersect themselves. For example CR 657 North along Evergreen Road goes all the way to NJ 27 (https://www.google.com/maps/@40.5592262,-74.3404838,3a,75y,60.59h,79.76t/data=!3m6!1e1!3m4!1sT9XUCMcF3NVPyS_0XJDXiA!2e0!7i13312!8i6656!5m1!1e1!6m1!1e1), but Thornall Street which intersects Evergreen just short of 27 is also CR 657 (https://www.google.com/maps/@40.5658041,-74.330874,3a,75y,112.37h,84.11t/data=!3m6!1e1!3m4!1s-qHffgt3yesrhIZQRDPU6Q!2e0!7i13312!8i6656!5m1!1e1!6m1!1e1). Meanwhile CR 657 South along Parsonage Rd goes all the way to US 1, but Lafayette Ave is also 657, and crosses Parsonage just short of US 1.

[hbelkins]

If VDOT is never going to connect them up (SR 730 was removed as VA 42 but the other current gap has mostly always been secondary) after 80+ years, they should renumber the southern extension as part of VA 91...

And do what with the section of 91 between Broadford and Tazewell (the gravel section)? Turn it into a secondary?

[kphoger]

I thought this was 2 state routes.

It seems to me that is how this topic started out.

At any rate, Texas has a boat load of duplicate, unrelated state route numbers.  The primary and secondary numbering overlaps greatly.  I'm not aware of any pairs that intersect, however.  Although the portion of the Camino Colombia between Mines Road and the Mexican border is officially SH-255, it is still signed as FM-255 until at least 2014 (the last time I drove that way).  So, although technically inaccurate, here is a GSV of a shield assembly near the intersection of the two state routes [Toll-SH-255] and [FM-255].

Yes...even most of the paved portion up to US 19-460 Bus is not up to primary standard and has no striping.

I also find it weird (unique?) that an unpaved highway has a Business-Bypass (Glade Spring) scheme not far away...

[jwolfer]

Another Florida pseudo example is SR20 which is signed from Palatka to Gainesville and then from Tallahassee to Niceville(?). It becomes subservient to US 441  and 27 in between.  SR 20 used to be routed along SR 100 to US 1 in Bunnell, but i never saw it signed in my lifetime, just on maps

For example CR 657 North along Evergreen Road goes all the way to NJ 27 (https://www.google.com/maps/@40.5592262,-74.3404838,3a,75y,60.59h,79.76t/data=!3m6!1e1!3m4!1sT9XUCMcF3NVPyS_0XJDXiA!2e0!7i13312!8i6656!5m1!1e1!6m1!1e1), but Thornall Street which intersects Evergreen just short of 27 is also CR 657 (https://www.google.com/maps/@40.5658041,-74.330874,3a,75y,112.37h,84.11t/data=!3m6!1e1!3m4!1s-qHffgt3yesrhIZQRDPU6Q!2e0!7i13312!8i6656!5m1!1e1!6m1!1e1). Meanwhile CR 657 South along Parsonage Rd goes all the way to US 1, but Lafayette Ave is also 657, and crosses Parsonage just short of US 1.

But to further complicate this issue, Parsonage Road is actually CR 630 (though Middlesex County hasn't communicated any of their county route changes to NJDOT in over 15 years). The real fun starts when you get to Monmouth County where you have juggernauts like this where you can go either north, south, or south on CR 4.

See also NJ 7 with two distinct (but not intersecting) segments.

Pretty famous, and mentioned in threads elsewhere on this site, but Maryland has a state route 68, and I-68 in the same county with interchanges on the same freeway (I-70, exit 18 and exit 1A, respectively). There are signs (here and here) on westbound I-70 approaching Exit 18 to inform and warn drivers that MD-68 is not the same as I-68.

Curiously, I am not aware of any similar signs on I-70 eastbound coming out of Pennsylvania.

Louisiana is similar, it has a note that LA-59 and I-59 are not the same route.
