Mainline Interstates That Terminate Into 3dis

[ethanhopkin14]

Looking at the current northern terminus of Interstate 49 in Kansas City, I get upset it terminates into I-435 (or I-470, I am not really sure where the signage stops).  I would rather it continue on US-71 and terminate into downtown Kansas City so it can party with the rest of the routes.  It got me thinking about how many times in the system do mainline interstates terminate into 3dis, giving them indirect access to another mainline interstate?

I-22 into I-269 south of Memphis?

I-88/IL eastern terminus in Hillside @ I-290 and I-294

One could make the argument that the route across Chicago's West Side to the Circle Interchange and Congress Pkwy Downtown should be numbered I-88 instead of I-290, but it is not

[wriddle082]

Eastern ends of I-64 and I-70.

[ilpt4u]

Still at present: Original/Northern segment of I-69 at the southern terminus @ I-465 NE side in Indy. Once INDOT finishes the Martinsville-465 SW side segment, then I-69 can come off this list

I-97 at both ends (695, unsigned 595)

In Raleigh, NC, I-87 actually has a 3 mile overlap with I-440 so that it can properly end at I-40. Otherwise, it would just end at I-440 and require travel on I-440 to reach I-40. Once (if ever) it is built into Hampton Roads, it will likely terminate at the I-64 / I-464 interchange, though there's been speculation on this forum that it may replace I-464 and continue north into Downtown Norfolk, where it would terminate at I-264.

I-64 in Hampton Roads terminates at I-664 / I-264, though since I-64 is the only interstate in/out of the area, there's no using 3di to connect to another interstate, though technically following I-664 does loop you back to I-64 in Hampton, and significantly cuts off the distance using I-64 back around through Norfolk.

Eastern I-76 terminates at I-295. Many have argued that I-76 should continue on NJ 42 and the Atlantic City Expressway to the shore...

[webny99]

On a tangentially related note, I-390 is sort of like an extension of I-99.

Although I-99 technically ends at I-86, the fictional proposals to extend either I-99 or I-83 to Rochester (via a multiplex with I-86) are never-ending.

I-4's western terminus is at I-275 in Tampa.

[ilpt4u]

At the moment, I-11's Northern Terminus is at I-215 and I-515. Not for too much longer, tho

[jp the roadgeek]

The REAL I-87 terminates at I-278

And I-70 for all intents and purposes terminates at I-695

[kurumi]

In the early 1980s, the plan was to have the eastern I-84 terminate at I-395 (RI cancelled their segment before CT did)

Why is this a problem?  Some 2DIs don't even terminate at other Interstates, even ones that don't go to Canada's or Mexico's border crossings.

I-90 doesn't end at an interstate at either end.  It ends at WA 519 at its western end and MA 1A at its eastern end.

[Roadgeekteen]

I-45 and I-345.

[Ketchup99]

Does it matter? An interstate's an interstate.

[sprjus4]

I-45 and I-345.

I-45 also terminates into I-30 at that junction, which connects to I-35E.

It doesn't "matter", it is just an observation since the original plan was to connect these mainline interstates in the downtowns of major cities.  We have gotten a little away from that where we see main line interstates terminate into 3dis, indirectly connecting them to another 2di in the same metro area. 

It is just like "that guy is tall and his friend is short"  there isn't a problem, just an observation.

Technically, the eastern I-84 ends at I-380 near Scranton/Wilkes-Barre, although they both continue to their mutual end at I-81.

Fair enough.  To be brutally honest, there's a good reason why I-49 doesn't go to downtown Kansas City: the expressway and partial freeway shouldn't have even built in the first place, and the land should never have been taken from those neighborhoods.  That alignment of US 71 is a relic of racist land acquisition and freeway building policies.  Completing the middle portion as an expressway instead of a freeway was a problematic compromise, because it poses serious safety problems.  However, it will be hard to fix it in a manner that honors the neighborhoods' needs, and it's often a subject on Fictional Highways and other boards here.

Actually, if you go back far enough, the original concept for Interstates was not to have them go through city centers but rather have them go around them, in a similar fashion to the Pennsylvania Turnpike.  But then Robert Moses, racism, and abuse of the Urban Renewal program happened.

As for the Kansas City example, I could think of several re-numberings that would connect all the 2DIs together without pushing I-49 through the east side and to Downtown, but again, that's a topic for Fictional Highways, and some of the ideas have already been discussed there.

I-70 ends at I-695 for a similar good reason.  I could think of one or two Fictional Highways re-numberings to connect the 2DIs around Baltimore, too.  The thing is, re-numberings rarely happen IRL because of the potential to cause confusion, at least in the short term (although, some re-numberings could really have a long-term navigational benefit in terms of systematic "clean-up").

Why doesn't I-76 continue onto the Atlantic City Expressway instead of ending at I-295?  That's a good question, and I think others have posted answers before.

I could think of a Fictional Highways re-numbering to connect I-22 to I-55, and that one's so new, it makes me wonder why they didn't number it that way in the first place, unless it's a case of "Worship the Mighty I-69!"

I am not a fan of renumbering highways unless they were spurs before and became a part of the new longer 2di, so my intention of this thread wasn't to renumber anything, just more of what other 2dis am I not aware of that terminate into 3dis?

It's more like I-380 ends at I-84, since mileposts only show I-84 distances and not I-380.

In this case, planning and official designation of I-269 came before I-22.  We knew it was going to be I-269 two decades before I-22 came about.

Well, actually they're about as old as each other, as I think my first correspondence about renumbering US 78 to I-22 with Senator Shelby's office was written about 1997 or 1998.  Although I-69 was legislated in 1998, indeed I-22 wasn't legislated into existence in 2004.
.
I think most of us expected Tennessee to be willing to upgrade US 72 at least to I-240.  If 22 ended there, it still would be ending at a 3di though!  I think part of the "Bridges of Memphis" solution should be to route I-22 along I-269 and I-69 towards Tunica, and build a new bridge and connector route sweeping across the river and northward to end at I-40.  Then traffic coming from I-30 & I-40 points west could completely bypass Memphis to the south on such an extended I-22...  Then building a new I-55 bridge a thousand feet south of the current bridge could proceed without making Memphis a permanent traffic jam.
