Title: Interstates that end at state lines
Post by: bugo on February 18, 2014, 10:57:55 PM
I-540 in Arkansas ends at the Oklahoma line (although unsigned).  Do any other interstates end at state borders?

Is this the case for the west (north) end of I-26 in Tennessee?

I-276 absolutely qualifies for this, until the junction with 95 is completed.

IIRC I-95 currently becomes I-276 at the state line. I-74 and I-69 overlap I-77 and I-55 to state lines.

That's probably all, unless you count I-49 north of Texarkana.

No, which leads to bullshit exit numbers that begin at US 11W rather than the state line.

If the end were where you expected it to be it would be an interesting case indeed... since the end of the designation and the location of the state line would be only indirectly related - i.e. it'd end at the state line because the freeway was built to end at the state line, not because the state line was deliberately the cutoff for the designation.

Or the northern ends of I-5, I-15, I-29, I-75, I-69/94, I-190, I-81, I-87, I-89, I-91, and I-95; and the southern ends of I-5 and I-110. :spin:

69 and 74 are supposed to be extended so they don't really count.  I-49 near Texarkana enters Texas for a few feet, so it doesn't count either.

When did I-276 officially get extended to the PA/NJ line? I'm not disputing that it is–the current FHWA Route Log shows 32.65 mi., which is almost exactly the distance from the Valley Forge Interchange to the state line.

But I seem to recall that the official designation formerly terminated at I-95–I assume owing to the fact that (at the time) the NJ Turnpike in Burlington County was not currently nor planned to be given an Interstate designation. And I also remember some historical accounts discussing the designation of the addition of PA Turnpike to the Interstate System having a caveat: ("...except a short portion at the Eastern end" ).

Does anyone know more about this?

No, which leads to bullshit exit numbers that begin at US 11W rather than the state line.

If you're going east, US 11W is the first exit. Going west (or north on US 23, if you prefer, the route divides into a couple of one-lane ramps, one to stay on 23 and the other for some Tennessee state route (either 36, which is old US 23, or a 3xx route).

US 85 :bigass:

A bunch used to end at the PA-NY line. US 220 comes the closest now, but it does barely enter NY.

There are a few bannered routes where one state doesn't like the route (anymore), e.g. US 1A MA-RI (unless RI has downgraded it), US 2 Biz WI-MI.

Oh shit. US 25. (Unless you consider it to end some tens of feet north.)

I-16 has a situation somewhat similar to I-26, where it ends at city streets but a freeway (in this case US-17 / SPUR-GA-404) continues to the state line.

If we're going to talk about US routes, there is also US 46 which ends at the NJ/NY border on the George Washington Bridge

Also NJ's portion of I-676 may or may not end at the NJ/PA border on the Ben Franklin Bridge depending on whom you ask. The signs seem to imply it's continuous with PA's I-676 through the short surface street section, but at the same time, going east from the PA side of I-676, the I-95 entrance is the pull-through and Ben Franklin Bridge (complete with an I-676 shield) is "Exit Only". Never mind that it's a split and only the right lane would be "Exit Only" even assuming it were an exit.

Some stretches of US 1A in RI now sport RI 1A shields.

Such shields were a contractor error or a rumored down-grade has indeed taken place.

US 65 formerly ended at US 61 in Natchez at the same location where US 425 ends now. It may have ended at the state line prior to being extended to New Orleans in the 1930s, though most likely it crossed the river (no bridge then, just a ferry). US 98 did end at the MS-LA state line for a time, at least according to signage.

If (and this is a big IF), I-580 in Nevada were extended north of I-80 in Reno, it would have to end at the Nevada/California border because...

1. I-580 already exists in California
2. California does not allow route number duplication
3. The road downgrades to a 4-lane expressway with at-grade intersections north of the stateline.

To be a tad more articulate: I-19 and I-35 both end near, but not at the border: in both cases it's a brief trip on city streets from the end of the freeway to customs. The other examples I gave have the interstate feeding directly into customs with no local roads in between.

I-96 also fails to qualify for similar reason: it ends at I-75, it does not continue onto the Ambassador Bridge.

According to signage, but per MDOT it ends at US 84 Bude...though wouldn't be the first time Mississippi signage didn't line up with what officially exists (or doesn't).  Also never got a good answer from MDOT as to when US 98 acquired its Bude terminus.

Similar for the new I-69E in Texas (ends a few at-grade intersections north of the border).  I-69C doesn't come close, ending at I-2.

I-69E might yet reach the border some day.  Of the at-grades, we have a right in/no out that could be restriped as a ramp (or cut off), a signalized intersection that could easily become an interchange, a no in/right out that can become a ramp or cut off, a RIRO that can be cut off, and the customs complex which we can ignore.

Before the completion of the Mark Twain Bridge, I-72 was wholly within Illinois and it ended fairly close to the state border.




Also, while formally I-80 ends in Teaneck, NJ at the I-95 junction, there is enough "informal" indication, including BGSes that seem to indicate that I-80 westbound begins at the George Washington Bridge.

Technically although signage for both I-22 and I-69 ends at state lines (AL/MS and MS/TN, respectively), the adjoining state has approval from FHWA to sign the route in their state but has chosen not to at this time.
