Exit 0 (Zero) on Interstates or Interstate Standard Highways

[Mapmikey]

Perhaps I'm misremembering, but I could have sworn that my first encounter with an Exit 0 back in the late '90s was on I-581 near Roanoke, VA. What made it even more of an oddity was that the gore sign had EXIT 0 in the center with diagonal arrows on both sides, looking kind of like a confused person shrugging his shoulders.

GSV from the August 2013 on the northbound I-81 side of the split shows a sign similar to what I described, but as Exit 1 and not Exit 0 (and oddly enough, earlier signs in the sequence reference Exit 1 N-S instead of A-B, which was a practice I didn't think VDOT engaged in).

A more recent 2015 GSV photograph taken in the southbound I-81 side of the split shows the gore sign having been replaced with an unnumbered sign with an I-81 shield in the center and opposing arrows for NORTH and SOUTH.

Maybe I'm mistaken, and it never was Exit 0, but can't imagine that I dreamt it. Does anyone here know for sure?

This June 1969 video shows it was Exit 1N-S back from the beginning...the relevant part is 0:55 and later.  Exit signs are on the sign supports and not the BGS's

IMHO, if there ever was a poster child for using Exit 0; the Lowell Connector would be it.

IMHO, if there ever was a poster child for a completely pointless highway, built solely for the sake of building a highway, the Lowell Connector would be it.  That or I-395 in Baltimore City, which is effectively a glorified exit ramp from I-95 to the downtown area.

Do keep in mind that there were plans to extend it beyond its current terminus; but, like a lot of other highway plans, such never came to fruition.

That road's even shorter than the Lowell Connector; it's just over a mile long.

Surprised no one mentioned the GSP:

There's one on I-355 at I-80

I think the western terminus of I-94 at I-90 near Billings is an Exit 0.

Someone did mention it

The only exit zero in NJ is on the Garden State Parkway.

Maybe I am misremembering, then. Great old film footage, though–I found some other old highway-related films in their collection. Thanks for sharing it.

Michigan doesn't use Exit 0, but there are a few cases where there could be one:

- I-96 at US-31 and Hile Rd, signed as Exit 1A-B-C
- I-696 at I-96 and I-275, signed as Exit 1
- I-275 at I-75, unnumbered
- I-196 at I-94, unnumbered
- M-6 and I-196, unnumbered (its eastern exit with I-96 is also unnumbered)
- I-496 at I-96/I-69, unnumbered

In the last three cases, Exit 1 exists on each freeway at a surface road.

There are a few such places in Georgia that theoretically could be Exit 0, but none of them are:

- At the west end of I-520, the I-20 interchange is Exit 1A-B.
- At the south end of I-185, the US 27/280 interchange is Exit 1A-B.
- At the southwest corner of I-285, the I-85 interchange is Exit 62, numbered as being at the end of the route and not the beginning.
- GA 400 uses sequential exit numbering. Still, when the southbound 400 to northbound I-85 ramp opened recently, it was given the number 1A; the existing Exit 1 for Sidney Marcus Blvd was renumbered as 1B.
- At the southwest corner of the Athens Perimeter, which does use mileage-based numbering, the US 29/78 interchange is Exit 1.

Safe to say Georgia has no interest in Exit 0 as a concept.

Also I-16 at its west end at I-75 has the I-75 south left ramp signed as "Exit 1," while the I-75 north ramp has no numbering, I guess because that was considered the I-16 mainline. I have no idea whether this will survive the interchange reconstruction; design plans should be coming in the next few months before it is let in September since these signs are understandably omitted from the I-16 signage replacement project that was let last month.

It's odd to see an up arrow (gore sign) and a down arrow (84 West) so close together.

This should be most of them, though some may be missing.

There are no Exit 0's in California so I'm not sure why CA-13 and CA-110 are listed here.  Caltrans' exit numbering policy states that any exit from mile 0 to mile 1.5 shall be signed as Exit 1.

NJ's GSP Exit 0 is missing.

[vdeane]

Is that list by any chance from CHM or TravelMapping?  The original policy on those sites was to use 0 at the beginning of a freeway if there was no number (that has since changed, but not every region may be updated yet).

[jeffandnicole]

Delaware now has an Exit 0. I-495 South's exit for I-295 North is marked as Exit 0.

[US 89]

As an example, there is no exit 0 on I-70 in UT. The Cove Fort exit is numbered 1, and the split at I-15 is unnumbered.

PA 66 has exit 0A/0B in New Stanton for US 119 and the connector to I-70/I-76

Apologies for reviving this ancient thread, but why doesn't I-95 at the North Carolina-South Carolina border have an exit 0?

I was watching a YouTube road trip video and the person stopped at South of the Border, SC. I looked it up and saw that the interchange is split in half by the state line (GSV link).

The nearest exit 0 to me is on I-10 in Anthony, TX and the entirety of that interchange is on the Texas side of the border. If there was ever a good candidate for an exit 0, it's I-95 at the NC/SC state line.

Among all the interstates in NC/SC, is there one with Exit 0? I only checked I-74 and I-140 just now but I saw exit 210 and exit 1. To be fair, no interstate in California have an exit 0, only exit 1 and letters if there are multiple exits nearby.

Now here's an Exit 0 that hasn't been mentioned pictured in this thread in I-270 in Colorado

[Scott5114]

Did they seriously both a bubble shield right over top of a correct shield on the 270 there on the side?

Just north of the KY/TN line, on northbound Purchase Parkway (future I-69) in Fulton, KY, there is an Exit 0, which apparently serves the Greater Fulton suburbs of Weigh and Station:

And now it's unnumbered again.

And going south, Fulton and Hickman are the destinations signed.
