Lowest exit number that doesn't exist in your state & where to put such an exit?

I've never seen an Exit 19 in WA, so I'd put one on I-5 for a connection to NW Griffith Road, south of Woodland.

(BTW, this sounds more like a topic that would belong in Fictional Highways, since we're discussing ideas for the lowest unused exit numbers in various states.)

Might as well do RI.  Historically, it would have been 31, as I-95 went up to 30.  Now, the lowest number is 12.  Only 3 roads with exit numbers (I-95, I-295, RI 146) are at least 12 miles long (US 6 has an expressway from the 15 to the 20 MP but no numbers).  The best (and a legitimately needed) Exit 12 would be a direct exit on I-95 to RI 165 and RI 3; RI 165 crosses at the 12.1 MP, and one must exit at Exit 9 (NB only) and travel 3 miles up RI 3 or Exit at RI 102 and go 2 miles to it.  RI 165 is a back way to the Norwich, CT area for those who want to avoid the casinos and/or New London. 
Interstates I've clinched: 97, 290 (MA), 291 (CT), 291 (MA), 293, 295 (DE-NJ-PA), 295 (RI-MA), 384, 391, 395 (CT-MA), 395 (MD), 495 (DE), 610 (LA), 684, 691, 695 (MD), 695 (NY), 795 (MD)

I don't think there is a 19 anywhere in Utah. Easiest way to get one would be to build an interchange on Bangerter at 3500 South, which is probably coming at some point in the next 5 years or so.

There is no exit 12 in Alabama, and essentially no good place to put it. Either there's a suitable exit nearby, or just a lonely dirt path that might be close.

I-459 has a community with a tiny bit of ROW for a RIRO-type exit but I doubt the local urge, will, and need exists for that.

If they decide to number the exits on SR 255 Research Park / Northern Bypass, maybe we'll get an Exit 12. Not sure if that would coincide with a need for it.

Quote from: pianocello on October 11, 2024, 11:27:44 PMIowa doesn't have an Exit 14, as far as I can tell. Best place to put it would be I-380 and 76th Ave SW in Cedar Rapids.

I can't disagree with that, but I'm surprised they deemed McClelland, Iowa unworthy of an exit off of I-80. A road going west from McClelland that connected to I-80 could be Exit 14 and would be a quick connection to Council Bluffs and the Omaha area.

I could see that if Omaha/Council Bluffs suburbia ever expanded further east, but for right now McClelland has a population under 200 and its access to I-80 is not too bad via 270th St/ US 6.
Just curious, if the Des Moines southeast bypass was I-435 (or a similar number), would there be an exit 14 there?

Best place to put it on? Interstate 465. NB exit and SB entrance to 96th St.

Other options:
I-94 at Wagner Rd in Porter
I-65 at CR 600 S in Underwood
Indiana: counties 100%, highways 100%
Illinois: counties 100%, highways 61%
Michigan: counties 100%, highways 56%
Wisconsin: counties 86%, highways 23%

Quote from: TheCatalyst31 on October 14, 2024, 08:29:09 PMWisconsin doesn't have an Exit 14. The best place for one is probably County Highway J on I-94. It wouldn't be that useful, but it's a connection to a signed highway on a stretch with a decent-sized gap between exits, which is more than I can say about any of the other options.

There is a jughandle intersection for WI-26 at Old Koshkonong Road just south of Fort Atkinson that I think would be Exit 14.

I saw that one, but it looks like it would be 15.

To complete New England, Maine would be 12.  There are only two roads with exit numbers that are that long: I-95 and I-295.  An I-95 exit 12 could be used for Clay Hill Rd, or a connector road leading to Ogunquit (an exit 13 leading to Berwick Rd would be better).  I-295's would be too close to the Falmouth Spur/US 1 exits and would be redundant.

US 89

So turns out there is a 19 on SR 7 southeast of St George. It's a half interchange that currently goes nowhere, but it counts.

That means the lowest that doesn't exist in Utah is 28. The easiest way to get a 28 in Utah now, and something I would love to see, is some sort of exit off of 215 that connects to US 89 in North Salt Lake. Some variant of this idea has been thrown around with the I-15 Farmington to Salt Lake expansion/reconstruction project, but I'm not yet sold on that actually happening in its current form. But that's really the only viable spot for a 28 anywhere in the state as all four primary interstates have their mile 28 either very close to an existing rural exit, or way out in the middle of the desert. Anything else with exit numbers either is not that long or isn't a freeway at that point.

There actually used to be a 28 in Utah - it was the Redwood exit on I-215 in Davis County. It got renumbered to 27 when the Legacy Parkway interchange opened.
