What do you suspect would be the LAST number used for a new interstate?

Not sure if this belongs in Fictional Highways or General Highway Talk, but here goes.

So we all know that there are many unused numbers that could be assigned to future 2di interstates, such as I-1, I-18 or I-62. My question is, of all the numbers remaining, which number do you think would be the last one to be assigned and why?

I-6 is a candidate for never being assigned, unless it would be an intrastate route in Texas.  Why?  Primarily because there's no place for it to fit into the grid outside of Texas.

Other routes that make no sense, if only because they wouldn't fit into the grid or there's nowhere for them to connect:

13, 18, 21, 23, 28 (unless that or 32 is used for a route connecting Memphis with Huntsville and Atlanta), 33, 34, 36 (which is what the eastern section of I-74 should be designated), 38, 42, 46, 52 (unless there is the unlikely route between Wichita and Denver), 54, 56, 58 or 62.

13, because Americans are a superstitious lot and would rather use something out of the grid.

There is already a US 13.  I would think the real reason would be that there would be nowhere in the grid to fit it.

Not sure if we will ever see an I-50 or I-60 either.  Normally the I-X0 routes are the longest east-west routes, I-30 being the lone exception.

Isn't I-32 supposed to run between Amarillo and Dallas along US 287 or is that some idea that has never been made official?

Interstate 1

I mean, where would you put it?

On US 101 between LA and San Francisco. That's where I'd put it anyways.

It would have to be 50.

Because 50 is a number that would make sense for a major, cross-country route, but was never assigned for the reason that it would conflict. It wouldn't really work for any other EW interstate existing already. It would have been used right from the start otherwise.

We probably will never see another cross-country interstate built.... certainly not in the part of the grid where an I-50 would go.

Since there are some newer posters in this thread I will link to something I posted in 2013...

Technically there has been an I-50...

An I-13's place on the grid would likely have it serving Las Vegas, or other Nevada city. The casinos there would not stand such an "unlucky" number in their vicinity, even if it might work elsewhere. I suspect they breathed a sigh of relief when 11 was chosen instead for the Las Vegas-Phoenix corridor.

Interesting responses. My guess is that the last available 2di to be assigned would be an even number in the 50s simply because 50, 52, 54, 56 and 58 are all available. Given how some interstates don't really fit in with the grid anyway, I don't see this stopping I-50. But the lack of other even-numbered roads in the 50s suggests one of these would be last.

I would rule out any of the even numbers between 28 and 48, simply because that is NC's location on the grid...

Given that I-50 sounds nice, to me at least, it may be used for some Congressman's pet project regardless of its location in the grid or length. I'd put I-58, as the last used number on an interstate, just for shits and giggles as the grid between the 30's and 50's makes those numbers difficult (but not impossible if the political pressure is there)

41 (or 2, depending on how you interpret "last") is probably the most statistically likely number to be the last new number that will ever be used.

Isn't 11 newer (as in not signed yet)? And 7 or 9 will probably happen in California.

The only number between 1 and 99 not used for an interstate or US route (I mean, like ever) is 47. So that one.

I'm not a scholar when it comes to US routes, but is there any particular reason why US 47 doesn't exist?

I would doubt that; there are a couple places out there that have candidates for future 2di's such as:

* The Kentucky Parkways not going to be part of I-69 or an I-x69.
* Some corridor in North Carolina
* I-380 and the Avenue of the Saints between US 20 and I-35 - If Iowa keeps have to put interchanges on the Avenue, it won't be that hard to fully upgrade this part
* The corridors Wisconsin may look into converting into freeways over the long term


On a somewhat related note, there is also the possibility of something coming out of the new federal transportation bill (mentioned in the I-69 in Texas thread), which has couple sections that mention looking into upgrading a couple of the NHS routes into interstates:  Link



As for my guess for the last 2di number to be used:  I-23, with I-1 and I-60 never getting used.

tidecat

I will concur with I-60 never being used, unless if California wants to upgrade CA 60 like it did CA 238.

The more appropriate place for I-60 would be along I-238, I-580, and I-205.  If it weren't for all the national parks in California, there actually would be a path along US 6 towards I-15 in Utah.  Of course there will likely never be any justification to build a freeway through that part of Nevada.  That routing would be the only way to keep US 60 and I-60 separated, and actually keep I-60 in proper grid sequence. I-60 could even make it as far as Kansas if you find some way to get across all the national parks in Utah and the mountains in Colorado.

I would argue that 1 and 3 are taken due to Alaska, Hawaii, and Puerto Rico, even if they are prefixed with letters.  There is of course the proposed I-3 for Georgia and Tennessee.

I actually could see I-13 or I-23 being the last odd number used due to where they fall in the grid.  Idaho may grab 13 if it feels travel in the western part of the state needs improvement, and Washington State or Oregon could get involved depending on the routing.  Where I-23 would naturally fall, there just aren't many people or even towns in Western New Mexico, Western Colorado, or Central Wyoming.  If Montana built anything north of Billings, Montana would have a good case for extending I-25.
Clinched: I-264 (KY), I-265 (KY), I-359 (AL), I-459 (AL), I-865 (IN)

I could see US 58 in Virginia being upgraded to an interstate at least from i95 east. Precedent in US74/i74 or 41.
