Renumbering the interstate grid

[FLRoads]

Just wanted to see how any of you would renumber the current interstate grid to fix some of the current issues it faces (i.e. I-99 in PA).  How would you number the interstates throughout the country?  I would like to hear your inputs on this. 

   

[Alex]

Interstate 99 goes to Delaware
Planned Interstate 49 south of Interstate 10 becomes Interstate 6
Interstate 74 in North Carolina becomes Interstate 38 or 42

Just to name a few suggestions  ;D

[deathtopumpkins]

Just move all the low digits to the west and high digits to the east. I mean how hard is it to just put the numbers in order (don't answer that--logistically I know it is rather difficult).

And remove a number designation from the I-64/I-664 mess, signing it simply as the Hampton Roads Beltway. 

[rawr apples]

I say we just get rid of the way we number than, other than East/West = Even , North/South = Odd

All it does is force interstates to have an out of place number when there is no other numbers available, and everyone complains in some way

I'd also let freeways that overtake the path of a Federal route to carry the number of the federal route, or any numbered route thats no longer in use for that matter. So I-95 would overtake US-1 and therefore be I-1, except US1 is still in use, but you get what i'm trying to say?

Change I-99 to I-81, and present 81 to 83 from Harrisburg to Canada. Between the 99 corridor and Harrisburg, perhaps change this to a spur off of either one?

Make that proposed I-3 another number. 18 comes to mind.

So would you have I-81 piggyback along I-70 westward into PA to meet up with your new I-81 (former I-99)?  I like the idea of extending I-83 northward from its current terminus though.

I-18 wouldn't properly fit into the grid, but if you reverse the numbers and have an additional extension of I-81 on a portion of that route, that could work.  Just extend I-81 south along I-40 to Knoxville to meet up with the proposed route, then route it south to meet I-85 in South Carolina.  I-81 could then follow current I-85 while rerouting I-85 onto the proposed route.  Then the new I-85 would head southeastward to meet I-95 in Savannah.  All former I-x85's in the Atlanta area as well as I-185 would have to be renumbered to I-x81's.

Either one of those would work in my opinion.

And that I-3 scenario could work as well. Although you'd still have the numbering issue from Atlanta to Montgomery on 85's route.

Renumber I-84 to I-82 and renumber I-82 to I-7

[Alex]

Renumber I-84 to I-82 and renumber I-82 to I-7

Interstate 82 originally was correct, sitting between Interstate 80N and 90. I like the idea, though if U.S. 395 is ever upgraded going northeast to Spokane, and the I-7 concept took place southward to Bend, you'd have to come up with a new number for I-82 northwest to Yakima and I-90. 

[Chris]

How about renumbering US 101 to I-3 and SR-99 to I-7/I-9?

Here's something I dug up about "I-7":

DE 1 could become the new I-99.

[Darkchylde]

Planned Interstate 49 south of Interstate 10 becomes Interstate 6

Seconded. It just wouldn't work as an odd number.

Also, I'm probably one of the few who would want suffixed routes back, in which case, redesignate I-12 as I-10N and current I-10 between Baton Rouge and Slidell as I-10S.

[John]

Suffixes are better than interstates going across each other (like I-89/I-91) or having roads way out of place (I-99, US 412, etc)

[Revive 755]

Also, I'm probably one of the few who would want suffixed routes back, in which case, redesignate I-12 as I-10N and current I-10 between Baton Rouge and Slidell as I-10S.

I also think the suffixed routes should come back, barring a complete renumbering of the interstate system.  There are a few places they could be used to help free up scare 3di's:

* I-70N over MO 370 and I-270
* I-70S over I-470, I-435, and KS 10 should the latter ever get a freeway bypass around Lawrence
* I-80N/I-80S around Quad Cities
* I-80N replacing I-680 around Omaha

Then there a few cases where splitting a main route might work better:
* I-95E/W in Maine
* I-93E/W in New Hampshire and Massachusetts, with I-93W running over I-293 and US 3
* I-75W providing a Detroit bypass over US 23 and I-475
* I-5E/W in California, with I-5E running over CA 99
* I-70N over I-76, I-376 and the proposed interstate route along US 22 into Ohio

[WillWeaverRVA]

Renumber I-99 to I-480 if it doesn't become a 2di. Renumber PA 283 to I-383.

Renumber VA 288 to I-695. Change VA 895 (yes, I know it's not an interstate) to an extended VA 150.

VA 164 should be I-164, and I-264 from I-64 to Virginia Beach should be I-64. (In other words, I agree with the idea to do that, then make present I-64 from I-264 to its terminus an extended I-664).

US 34 in Illinois between I-74 and Monmouth should become I-174.

[un1]

So I-95 would overtake US-1 and therefore be I-1, except US1 is still in use, but you get what i'm trying to say?

Like what Ontario does with the 400 series.
410 (10), 420 (20), Future 424 (24), 427 (27), 407 (7), 416 (16) and 417 (17) are all ones that were named like that.

I think that they should just re-number all of them, the same way as before. I-5 could become I-1.

-un1

[agentsteel53]

I think I-1 should be the brief freeway section of CA-1 in Orange and LA counties.  Then, there could be a branch route of it that heads up all the way to the Bay Area.  Yep, none other than I-101.  More practically, that corridor could become I-3.

I-7 should be US-97, especially in Oregon.  That corridor definitely needs an upgrade.

I-9: if US-99 can't get its old number back, then the freeway section of CA-99 should become I-9 between the Grapevine and Sacramento.

I-11 should be US-395 heading up from Victorville to Reno.

I-13 should be US-95 from Las Vegas on south.  Yes, this puts it east of I-15 but there really isn't a better number available, except maybe I-915 (to reflect its old number, similar to how US-53 became I-535 in Duluth/Superior.)

[Darkchylde]

Change I-25 to I-21, then work east from there.

[agentsteel53]

Change I-25 to I-21, then work east from there.

very sensible, also if we make 3dis out of the single-state short 2dis.

I-25 -> I-21
I-27 -> I-140
I-29 -> I-23
I-35 -> I-25 (perfect!)
I-37 -> I-735
I-39 -> I-27 (it takes up two states, so it can stay)
I-41 -> I-29
I-43 -> I-390 and I-994... split the two halves (to Green Bay and to Beloit)
I-45 -> I-710
I-49 -> I-33 (and I-6 on that Louisiana 'future' section!)
I-55 -> I-35, as it is major
I-57 -> I-37
I-59 -> I-39
I-65 -> I-45
I-69 -> I-47 (Indy to Port Huron), don't get me started on the rest!
I-71 -> I-49
I-73 -> never to be spoken of again
I-75 -> I-55
I-77 -> I-57
I-79 -> I-59

now there is plenty of room at the top.

[FLRoads]

Yes, I would say that leaves plenty of room.

[agentsteel53]

even if we keep I-25 as a major route, thus leaving I-35 as is, we can take out I-37, I-43, and I-45, and thereby have enough room to make I-55 into I-45 and have still a lot of room at the top.

[FLRoads]

I have always felt I-45 needed to be longer anyway.  A major north-south interstate that never leaves it origin state.

[agentsteel53]

I have no idea how Texas got I-45.  Even if it's a legitimate 2di, shouldn't it have been I-39?  (this was before the one in Illinois and Wisconsin showed up.)

[Darkchylde]

I was thinking more:

I-25 becomes I-21 (current I-25 is not a true cross-country route)
I-27 becomes I-23 (or I-140 until expanded either to Denver or to I-10)
I-35 from KC south and I-29 from KC north becomes I-25
I-37 becomes I-27
I-45 becomes I-29
I-49 (including unbuilt from Shreveport to KC, not "I-49 South" section) and I-35 from KC north becomes I-35
I-49 "South" from Lafayette, La to New Orleans becomes I-6
I-39 becomes I-37
I-43 becomes I-39
I-69 (when complete) becomes I-41
I-55 becomes I-45
I-57 becomes I-47
I-59 becomes I-49
I-65 becomes I-55
I-85 from Montgomery, AL to Atlanta becomes part of future I-14 corridor (runs west from Montgomery to either Alexandria, La or Austin, Tx)
I-73's planned route is changed from Ohio and Michigan to PA to connect with current I-99 and overtake it
I-71 becomes I-63
I-75 becomes I-65
I-85 from Atlanta north becomes I-69 or something

...And from there, use your imagination.
