Interstates getting their own number

[Roadmaestro95]

The interstate highway system uses a number designation for two interstates that we all know will never connect. Shouldn't they use other number designations instead of repeating them? (Such as I-86 in Idaho and plans for I-44 in NC)

[agentsteel53]

there's a plan for I-44 in NC?

[bugo]

Wouldn't surprise me.  Maybe he's thinking of North Carolina 44, which will eventually be US 70, not I-44.

keep on topic here...

The general rationale behind duplicate I numbers (I-76 in CO/NE and OH/PA/NJ, I-84 in OR/ID/UT and PA/NY/CT/MA, I-86 in Idaho and NY/PA, I-88 in IL and NY) is to keep from breaking "the grid" more than it is now.  All even I-xx numbers between 64 and 96 are used.  So to renumber one of those duplicate interstate numbers you'd either have to make it a 3di or use a 2d number that is way out of the grid.

And, no I haven't forgotten about I-69 or I-74.  Both have plans to join the pieces though it's much more likely that I-69 will be one interstate than I-74.

Of course, we also still have those two copies of I-95!

you're right.  I'm sorry.  I will only discuss I-366 here.

[Takumi]

Yeah, the I-74 extension is really the oddest of all of them, especially since it not only exists in the same state as a US route with the same number (the reason there isn't an I-50 or I-60), but multiplexes with it!

[vdeane]

They probably should have planned for it with the grid.  Personially I prefer the numbers be a little off (as long as its reasonable) to duplicates.  So renumbering the duplicates is in (especially since many of the duplicates shouldn't be 2dis in the first place), but I-74 in NC and I-3 in GA are out.

I-86 begins in Erie County near North East PA and continues through the southern New York and ends is eastern NY.  I can't see them doing this it is very illogical

[Mapmikey]

Renumber I-82 as an odd 2di number

Put I-82 on current I-84 in the east

Renumber ID I-86 as a 3di

Renumber one of the I-88's as I-92.

Maybe suffixes should just be reintroduced. I personally never saw what the big deal was with having I-80 and I-80N. I don't think it's really all that confusing.

[hobsini2]

I personally have no problem with duplexes of a single number when there is a great distance between them or they both have an endpoint on the same road. No one is going to confuse I-76 in Denver with the one in Philly unless they are a dope.

[froggie]

Considering how many dopes have drivers licenses these days...

[agentsteel53]

that would be extraordinarily dopey.  the last time I ran into that mistake was when I tried my damnedest to find out how I-495 on Long Island connected to I-495 in Massachusetts.

I was six years old.

Actually I'd make i-82 an odd interstate because if you look at it...it really looks more south to north than east to west. I agree making I-84 in the east I-82 and ridding I-86 in the west completely. However, how can I-88 be made I-92 if it is south of I-90?

Perhaps this a dumb question...but is Interstate 98 in use anywhere?

[agentsteel53]

it is not, and I doubt the western US-2 corridor needs the upgrade.

In the eastern US, some New York communities are actively promoting the notion of a Watertown to Plattsburgh intrastate I-98 (I assume they envision interchanges with I-81 and I-87):
http://www.watertowndailytimes.com/article/20111221/NEWS05/712219939/0/FRONTPAGE

"The St. Lawrence County Industrial Development Agency agreed Tuesday to transfer $8,511 for Interstate 98 to the Business Development Corporation for a Greater Massena, removing itself from the reimbursement process.
The BDC will become a temporary conduit for municipal and agency contributions made on behalf of the Northern Corridor Transportation Group, which has spearheaded promotion in recent years of the proposed Watertown-to-Plattsburgh interstate." ...

I'd love to see US-11 turn into an interstate. It would be better and faster than staying along the Saint Lawrence.

[agentsteel53]

that might be better suited as I-887.  (I think it's a "loop" because it connects two interstates, even though it does not touch the same route at two points.)

[vdeane]

I said "many", not "all".  The western I-86 has no business as a 2di; I'd move I-82 onto the western I-84 and renumber I-82 either as I-7 or a 3di.  Both I-88s are similar in length to I-476.

Theoretically I-98 could be I-81 (it does follow US 11 after all).  IMO it's more likely that it will start on I-781 rather than I-81 itself.  There are a few other corridors it could connect to to make a longer interstate as well on the US 2 corridor.  Plus the number isn't in use.

Maybe I'd like to see this happen like it did way back when...

If it is the eastern 88 to be renumbered as 92, think of it as a diagonal interstate like I-24 or I-26 that don't match the grid exactly as-is.  This would have the added benefit of keeping I-88 in Illinois which could be used on US 20 across Iowa if anyone ever wanted to do that and it would still fit the grid.

The western I-88 could be eliminated by I-92 and gridded correctly if you did the real-world unnecessary step of making I-88 part of I-90 which would then have to use I-380, upgraded IA 27 and I-35 to get back to present I-90.  Then renumber I-90 through SE Minn, Wisc, and NW Ill as I-92

I actually don't think many people outside the roadgeek community think about the grid to this extent...
