Cases where one state DOT maintains something else in another state

[codyg1985]

I have noticed that TDOT maintains ITS infrastructure not only in Shelby County, TN, but also along I-40 and I-55 in Crittenden County, AR. TDOT maintains cameras, VMSs, and those "Tune into Radio Station AM xxxx when flashing" signs there.

Is there any other case where an outside DOT maintains something in another state?

NY maintains a couple of freeways that dip into other states (I-684 CT and NY 17 PA).  I-15 in AZ is maintained by Utah.

[froggie]

MnDOT maintains the half-mile or so of MN 23 that dips into the northwest corner of Wisconsin.

I believe NYSDOT maintains the stretch of I-684 that dips into Connecticut, but I'm not 100% on that.

Technically, the Maryland Transportation Authority maintains the short bit of the US 301 Nice Bridge and approach that's on the Virginia side of the riverbank (everything from mean low tide on the Virginia side east is considered Maryland).

The little piece of US-191 on the west side of Yellowstone in Wyoming is maintained by Montana.
Wyoming 70 is maintained by Wyoming where it dips into Colorado

I-15 in AZ is maintained by Utah.

No it's not- the presence of state-named shields would be the first clue, as is the AZ style signage and "Veterans Memorial Highway" designation

Kentucky maintains the entirety of the bridges that extend into Ohio. Thus US 25 ends in Cincinnati despite not being maintained by Ohio.

Not entirely true. Ohio maintains the US 23 bridge, and if I am not mistaken, the Ironton-Russell bridge.

In another Kentucky example, West Virginia maintains the two portions of US 52/US 119 that cross into Kentucky north of Williamson.

it is a crew out of St. George which does the actual work, but the contracts are all laid out to Arizona specification. 

another Arizona example: AZ-95 is signed in Needles, CA on green signs that are clearly of Arizona manufacture.  in fact, the easiest way to trace the route of AZ-95 is to take the bridge across into Needles, then south onto I-40, then back into Arizona where AZ-95 breaks off at exit 9.

so, in its own special way, there is an AZ-95/US-95 multiplex ... in California.

VDOT maintains the entirety of the US 29/US 58 interchange in Danville, even though half of it is in North Carolina. They also maintain the first half mile or so of US 29 entering North Carolina.

Parts of NY-120A dip into Greenwich, CT, however the road is entirely NYSDOT maintained and signed, less one erroneous CT-120A shield at the Merritt Parkway exit.

[Jim]

If we're willing to extend to Canada, here are a couple more.  The Klondike Highway section that cuts through BC to connect with Alaska Route 98 is maintained by the Yukon.  Same is true of the sections of the Alaska Highway south/west of Watson Lake that dip back down into BC.

I believe Virginia and Maryland maintain the smidgen of I-95 that passes through DC on the Wilson Bridge (though of course DC is a territory rather than a state).

[HazMatt]

Georgia maintains both small sections of GA 246 that cross into NC.

[ghYHZ]

How 'bout one country maintaining a section of road in another. In winter, Fort Fairfield, Maine plows a section of road in New Brunswick as the driveways of the US residents open onto the NB road.

Oregon DOT maintains the U.S. 101 (Astoria-Megler), I-5 (Interstate), I-205 (Glenn Jackson), U.S. 197 (The Dalles), and I-82 (McNary) Bridges across the Washington-Oregon state line.  Due to recent bridge work on the Astoria-Megler bridge one can find quite a few ODOT construction signs and ARRA signs on SR 4 and U.S. 101 on the Washington side.  The obvious sign is of course Oregon's "Speed, not Limit" signs on the bridge, however I believe ODOT has replaced the signs on I-205 with the universal "Speed Limit" signs.  There, the obvious reference to Oregon's jurisdiction is that the speed limit drops from 60 to 55 before you get on the bridge (the I-5 bridge is already at a reduced 50 MPH speed limit.)

WSDOT maintains the SR 433 (Lewis & Clark) and U.S. 97 (Sam Hill) Bridges.  "Washingon Jobs Now" signs could be seen on the western approach to the bridge while still on Oregon soil.

The Cathlamet Ferry is owned/operated by Wahkiakum County (WA).  The Bridge of the Gods is owned/operated by the Port of Cascade Locks (OR).  The Hood River Bridge is owned/operated by the Port of Hood River (OR).  And the Columbia Gorge Regional Airport (a.k.a. The Dalles Municipal Airport), despite being located in Dallesport, WA, is partially owned by the City of The Dalles (OR) and Klickatat County (WA).

I believe Virginia and Maryland maintain the smidgen of I-95 that passes through DC on the Wilson Bridge (though of course DC is a territory rather than a state).

I thought the whole bridge was federal, for precisely that reason (the weird geography).

Similar to Ohio, Indiana maintains the I-64 and SR 237 bridges over the Ohio River. Because the state line is the high water mark of the north bank of the river when Kentucky was made a state, these are better examples than the ones maintained by Kentucky.

I believe Virginia and Maryland maintain the smidgen of I-95 that passes through DC on the Wilson Bridge (though of course DC is a territory rather than a state).

I believe that was true of the old bridge but not of the new spans.

[SteveG1988]

Technicaly 95% of the delaware memorial bridge is in delaware due to the odd border. Low tide in NJ is the border in that area. Once you are half way up the approaches and over water...you are in delaware. It is operated by the DRBA a Bi State authority due to that reason.

Kentucky maintains the I-65 bridge in Louisville, and Indiana maintains the I-64 bridge, even though most of both bridges are in Kentucky, since the state line is close to the Indiana shoreline

Correct.  FHWA owned the old bridge.  VDOT and MD SHA own the new bridge, and in my experience (considerable, since it's my daily commute route) most of the maintenance is done by SHA.

On one of my 2008 road trips, I saw several ODOT-spec speed limit signs in an Idaho construction zone near the border.  But I'd assumed that the work was being done by an Oregon-based contractor, which had only Oregon-spec signs in its inventory.

Arkansas and Oklahoma have some deal with AR43/OK20. The road straddles the state line, but the sign assemblies are mostly Oklahoma (including the little mileage markers on the backs of the stop signs), though it has Benton County, AR County Rd Blade Signs (such as Hog Farm Rd  39 )

US 71 in Texarkana is split: one side is Arkansas signage, the other is Texas , but the traffic signals appear to be predominantly Texas-style (horizontal ) as opposed to Arkansas's vertical

[roadman65]

I imagine that the DE & MD 54 route along the DE- MD Line is most likely maintained by only one state.
What about State Line Road in the Metro-Kansas City area?  It cannot be maintained by both local or county agencies while the road sits in both states of KS and MO.

[Beeper1]

There is a section of NH 113 that is maintained by Maine where is passes along the ME side of a border-dividing lake.

While I don't frequent the bridge enough to know in detail whose trucks are out there ...

Per the 2001 ownership agreement, Maryland and Virginia share cost of the operation, maintenance and repair of the new bridges 50/50.
