Shouldn't Interstate 210 connect with its parent?

[blawp]

If it doesn't, it should be renumbered to Interstate 305, because it's really just a spur of the 5 at this point.

But it's California so anything they do is correct.

[Bigmikelakers]

After the CA 210/I-215 interchange is complete, Caltrans is supposed to petition CA 210 to become I-210. So one day, I-210 will meet with its parent once again. Should I-105 be called something else since it doesn't meet with its parent neither? I never knew aux routes actually had to meet with their parent routes. But, it does make sense for them to do so.

[PurdueBill]

Doesn't 105 start at 605 and extend past 405?  That is more than enough for it to be an X05--it's a child of a child of 5, kinda like I-190 Mass, I-795 MD, I-990 NY are branches off 290, 695, 290.

As stated above, the 210 numbering will be totally kosher when CA 210 becomes I-210.  It will have one end at I-10 and the other end at an interstate, so the even first digit criterion will be met.

I-105 meets I-605, which is good enough to follow the rules.

there are other examples of that - I believe I-280 does not quite meet I-80 officially in San Francisco.

Correct (due to unconstructed portion between King Street and the old 80/480 junction, which was cancelled in the 1980s).

Interestingly, prior to 1968, I-80 was actually planned to terminate at I-280 in Golden Gate Park, when 280 was still planned in SF as a replacement for the current Route 1 surface street alignment along 19th Avenue and Park Presidio Boulevard!

Now, I-380 and I-980 are examples of I-80 3dis that do not meet I-80 at all and never were planned to.

It's closer to connecting than any of the I-x78s in New York.

Why do you keep trolling us with questions without looking it up?  What the heck is <eom>?

I-210 in the past used to connect to I-10 via what is now CA 57. When Caltrans decided to upgrade CA 30 to an interstate, they decided to truncate I-210 at CA 57 and sign the sections of already-complete freeway as CA 210, until the whole freeway and all the interchanges were complete. I guess once the CA 210 /I-215 interchange, the CA 905 freeway and the I-710 extension are complete, Caltrans will be requesting permission from the FHWA to sign them as interstates.

[blawp]

I feel like it will not happen in my lifetime, but we will see. If it doesn't happen, Caltrans should go ahead and re-sign the interstate as Interstate 305.

[Bickendan]

I-305 -- both California's incarnation and Oregon's terminated -- disagree.

[ljwestmcsd]

I-280 in CA meets with I-680 and I-880, so it qualifies even if it never meets I-80.

CA-210 can be I-210 without ever meeting I-10, or a child thereof. After all, we're talking California.

CA-238 became I-238 without ever meeting I-38, didn't it?

[Bigmikelakers]

How about an I-X15?

I-38 is the San Francisco Bay Tunnel and Express Route to the shore of Lake Tahoe.

Why in the hell should Caltrans renumber I-210 as I-305?!?!?   Don't you know I-305 is already assigned to the US 50 portion of BL-80 in Sacramento?  If you're under the age of 30 (and judging by your posts, you might be under 20!) you will see the CA-210 portion of the Foothill Freeway signed as I-210 within your lifetime.

If you had done some research, you would have known what National Highway 1 said in his post... that I-210 used to connect to I-10 via what is now CA-57.

FWIW, "eom" means "end of message" and while it may be appropriate under certain circumstances, I don't think it's appropriate in a message board posting.

LOL!  Seeing how I'm headed to Reno in a couple of days, where can I access this express tunnel!

Weren't the joint terminii of the original alignments of I-280 and I-480 on Doyle Dr at the approach to the Golden Gate Bridge (US 101) at what is now the junction of US 101/CA 1 (Exit 438)?

[JustDrive]

Is this a serious question?  I mean, unless you weren't around SoCal in 2007, you'd know that I-210 used to end at the Kellogg Interchange in Pomona, where it DID meet up with I-10.

And now for the actual serious question:  Caltrans really won't wait until the 710 extension is complete to submit CA 210 to AASHTO for Interstate designation, will they?

[myosh_tino]

I would seriously doubt Caltrans will wait until the 710 extension is built before asking to sign I-210. It is plausible that they might wait until the 905 freeway is completed so they can ask for I-210 and I-905 at the same time.  From what I understand, the final freeway segment of CA-905 is under construction.

Correct (though mid-1960s editions of the Rand McNally atlas once showed 480 continuing along Route 1 down Park Presidio Boulevard to Golden Gate Park at the proposed 280/80 junction).

The section of US 101 along Lombard Street, Richardson Avenue, and Doyle Drive (the latter now supplanted by the still-under-construction Presidio Parkway) was legislatively part of I-480, later Route 480, until 1991.

[national highway 1]

Why was I-480 demoted to a state route in 1968? Was it because it was incomplete like CA 210, CA 215, CA 905 etc.?

[bulkyorled]

Actually, I THINK there was a reason for it that doesn't relate to that (after all, the current 280 was never finished to 80 and retained its Interstate designation!) -

- in 1968, as a result of the freeway revolts in SF, the original Junipero Serra Freeway extension (planned 280 north of Font Boulevard to Doyle Drive), the extremely contentious Interstate 80 Western Freeway proposal (connecting 280 in Golden Gate Park with the Central Freeway), the 480 gap between Richardson Drive/Marina Boulevard and Broadway all got canceled (and 280 was moved to the mostly-completed existing Route 82 (former US 101) and planned-but-not-signed-as-Route 87 freeway that now leads to the baseball stadium). 

At the same time, the original I-105 (Santa Ana Freeway segment of US 101 between the San Bernardino Split and East Los Angeles Interchange) and I-110 (San Bernarndino Freeway spur/former US 60/70/99 between the Santa Ana and Golden State Freeways) in Los Angeles were decomissioned without having ever been signed.

All of this freed up Interstate milage was then transferred to what had been proposed as an upgrade of Route 42 to a new freeway alignment, but which now became today's I-105 Century Freeway.

One odd side effect - and I still do not know if this was intentional, to gain two more miles towards today's 105, or a paperwork mistake - is that the old US 40/50 viaduct that was added to I-80 in the 1950s has not officially been part of the Interstate system since 1968, but has ALWAYS been signed as I-80 regardless.  I've thought that that was a clerical error in attempting to rescind the mileage of the unbuilt Western Freeway from the Interstate system.

[swbrotha100]

You wanna renumber 210 to I-102, or I-12, or I-14? Those numbers were all considered back in the 1950s:

http://www.kurumi.com/roads/3di/ix02.html

[Quillz]

I-210 used to connect to I-10 and it will eventually connect to I-10 again, albeit farther east, once CA-210 is rebadged. The extended I-210 will effectively take over the former CA-30 routing.

You could also make a case that both CA-110 and (eventually) I-710 come close enough to I-210 to allow for the "child of child" auxiliary rule to take effect. As far as I know, 3di that at the very least connected to another 3di were always "legal" as far as the numbering was concerned.

[Desert Man]

I-210 stands for a route funded by the US Dept. of Transportation, while Cal. route 210 signifies only the state (CalTrans) funds the other section of the road. The Cal. route opened in a later time when the DoT already recommends more freeways to be funded by states instead, or in the case of FastTrak by private companies within a few counties approved private-funded roads, but they also carried state route monikers.
