Roads removed from interstate system.

[Crown Victoria]

Will also add the old southern terminus of Interstate 176 in Morgantown, PA, with an approximately one mile long section of freeway now designated as a quadrant route.

[-- US 175 --]

I-20 in TX between I-30/Loop 12 in Dallas, to where Spur 557 now intersects current I-20 in Terrell.

Is the I-515 designation going to be removed in Vegas? It's pointless now that I-11 is on that road as well. Obviously that's not relevant to the question here, but still.

NVDOT hasn't committed to routing I-11 on what's now I-515, which is still signed only as I-515/US 93/US 95, with no mention of I-11. Other options for extending I-11 through the Las Vegas area are in play in the ongoing environmental review process, though it would not surprise me if I-515 disappears sometime this decade.

There's a very long thread on this issue.

Ok, interesting, I thought for some reason that I-11 was already signed on I-515.

Also I-124 in Tennessee.

It's still there, just unsigned, though, isn't it?

I-480 San Francisco

I-80 ended up following the former I-880 and I-305 was substituted for part of it (from the former I-880, now I-80 "Stay Right to Stay On" to what is now CASR-51). After a 90 degree turn advise to 35 MPH, what is now CASR-51 (and signed as "Business 80") was removed from the Interstate system.

Which are in Sacramento, not San Francisco.

Now for one that will bring the tomato throwing...

GA 520 was officially placed into the interstate system from US 17 to Jekyll Island for 1 day as I-50.  That one day was May 7, 2006.  Why there?  That's where the AASHTO US Route Numbering Committee was meeting and they were doing a vintage car ride to celebrate the 50th anniversary of the Interstates...

This is really cool, and I didn't know about it. So I added it to the Wikipedia page for GA 520.

Also I-124 in Tennessee.

Yes, it's still in the system.

I-894 still exists for no apparent reason (other than Wisconsin really loves triplexed highways) around Milwaukee.

Depends on the confusion over how to sign the Chicago Skyway.


Technically most of I-90 west I-5 was deleted, even though it was never built, and the designation stopped at 4th Ave, instead of SR 99/Alaskan Way Viaduct.


I-505 in Portland was partially built, and supposedly signed, before being removed, properly terminated, and just becoming part of US-30.

Of course, I'm sorry that I didn't say so.

[ilpt4u]

Coming soon...the piece of former I-164 between US 41 and where the new I-69 Ohio River Bridge willl be built in Evansville. I guess that little piece could end up with an unsigned/hidden Interstate system designation of some sort, but I figured it would just become part of a slightly longer Verteran's Memorial Parkway like the highway west of the US 41 interchange is

[bing101]

I-880 Sacramento but there is a section of CA-244 that was supposed to meet interstate standards for the then possible Beltline freeway expansion until that was cancelled though at the now CA-51@ I-80 interchange .

[KeithE4Phx]

I thought that was settled several years ago, and it really is part of I-90 again.

Technically most of I-90 west I-5 was deleted, even though it was never built, and the designation stopped at 4th Ave, instead of SR 99/Alaskan Way Viaduct.

Same goes for I-710, a never-built freeway in Tucson AZ that was killed off in the mid or late 1970s.

[Hot Rod Hootenanny]

Also coming soon, in Cleveland, I-490 should get trimmed a 1/2 mile, east of I-77, when the Opportunity Corridor boulevard is completed next year. (It will then be signed as Ohio 10, east of I-77, for reasons only ODOT knows)
I do not know if I-290 was ever signed with I-271, between I-90 and US 422/Oh 87, before I-290 taken out in 1970.

I don't know where the gap at the Skyway came from. I have the improvement plans from 1960 . The Skyway was 94 then and Bishop Ford was 90. They were flipped about 1965. The numbers on the IKE and Kennedy were too. Part of the Kennedy was a state highway because it was a non chargeable segment. But nothing has been deleted. There was the crosstown that got a number and a South lake shore drive that did too they've ever never built.
There seems to have been some debate about 255 in metro east but it was done.
The only deletion discussion was the famed 180 that is so fascinating it should have a thread.....but it's bridges are being redeemed so it will stay. Illinois adds does not delete.

I had a 1978 atlas that showed I-90 along the Eisenhower instead of I-290, with the Kennedy between I-94 and IL 53/I-290 being IL 194 and the O'Hare Freeway (now I-190) being IL 594

[3467]

Yes I checked mine it appears the switch took place just after.
1965 Map had same but no number on Bessie Coleman. The Skyway Bishop Ford Switch was there.

Also toll  US 41 on the Tri State.

The change was in 1979.  I want to say May, but I'm not 100% sure.  I lived in Glendale Heights and worked in Rolling Meadows at the time, so the "Eisenhower Extension" was my way to and from work.  I drove to work on I-90 one day, and drove home that night on I-290.

IIRC, the I-90/I-94 swap was in 1964.

The TOLL US 30 on the East-West (Reagan) Tollway and the TOLL US 41 on the Tri-State were relics from the late 1950s.  They were removed in the mid '60s.

Oh, good point. Don't know how I forgot about that.

[PHLBOS]

Looks like PTC forgot that when they placed these overpass signs on such roughly a decade ago.

I-20 in TX between I-30/Loop 12 in Dallas, to where Spur 557 now intersects current I-20 in Terrell.

Yes, what is currently US 80 to Spur 557 was I-20.  I wish they had kept that freeway in the system and named it I-220

I-495 in NJ
