It is probably bad map data coming from governing agencies.  I can certainly see Fresno County doing something like that given the field signage they have in place.

The Interstate Guide's Business Route 5 page (https://www.aaroads.com/interstate-guide/business/ir-005/) says this about the business route through Coalinga: A Compass map from the early 1990s displayed a business loop to Coalinga, originating at Exit 325 and ending at Exit 337. The business route traveled west along Jayne Avenue to SR 33 north and Polk Street to SR 198 (Elm Avenue) in the city of Coalinga. SR 33/198 extended the route north to their split, with SR 33 (Coalinga-Fresno Road) returning Business Loop I-5 to the freeway. This route may never have been posted or was a cartographic error. Furthermore it did not appear in the Caltrans system signing log from 1991 and no signs have ever been observed for the route.

This is the kind of signage present directing traffic to I-5 in Coalinga.

Never seen a mileage number as part of the blue "to" signage before. I guess when it's 13 miles, people will start to wonder if they're going the right way.

Maybe it was a copyright trap.

Yeah that's the only location like that along CA 33 that I can think of off the top of my head.  I guess it makes sense, it isn't as though 13 miles is around the corner from town.

Sure, without that I could imagine someone driving 12 miles and saying, "This can't be the right route," and turning around and going back to Coalinga.

(That's assuming they don't have a smart phone, in-car nav, or even a paper map.)

Google is so polluted with fictional route designations. Where do these fanciful ideas come from? Is there some group of road geeks working at Google that just imposes their fantasies on the map, perhaps hoping that somehow their dreams will come true?

Where else? One that is led by an owl named Fritz.

Oh, I dunno.

This is even new signage - here's my pictures from a good decade plus ago.

We have someone on the wiki who has worked for companies that produce maps like this (I don't think he's worked at Google specifically). The stories he's told about people working on road map products who assume the entire world is just like the Bay Area and/or don't actually drive a car explains a lot about why Google Maps is such garbage sometimes.

Kind of looks like a toll road / turnpike sign.  Here are examples of blue South African and German toll road indicator signs,

Anyone know the story behind this?

[Max Rockatansky]

Fair amount of Old CA 30 combined with apparently new frontage road built south of the freeway corridor. 

[pderocco]

That was an interesting serpentine road to drive back when they were building the 210 freeway. I think it was still signed as 30, even though lots of it had been substantially rerouted to make way for freeway interchanges.

As you can see in this:

https://gisdata-caltrans.opendata.arcgis.com/datasets/77f2d7ba94e040a78bfbe36feb6279da_0/explore?filters=eyJSdGVTdWZmaXgiOlsiVSJdfQ%3D%3D&location=39.925244%2C-123.770124%2C13.74

there are unrelinqued bits of I-8, 14, 58, US-101, and 210 in Kramer Junction, Sylmar, Santa Clarita, Winterhaven, Willits, Piercy, LaVerne, Fontana, and Rialto, but only the Santa Clarita piece of 14 is signed.

Thanks for this map. I've been looking for a resource that shows an up to date map of the SHS including relinquished bits. I'm surprised there's an 8U. 58U is pretty fresh from the Kramer Junction bypass, and 101U slightly less fresh from the Willits bypass. Also surprised that Route 710 goes all the way to Columbia Street.

Finding this out makes it more surprising that 14U is getting relinquished, and is even getting the full "ineligible for adoption under Section 81" treatment.

Caltrans has been authorized since 2017 to transfer that part of old route 14 to local control, only the locality (Santa Clarita) has balked at taking it off Caltrans' hands. Is there any recent progress on actually carrying out the relinquishment?

[Max Rockatansky]

Santa Clarita apparently doesn't want the segment Sierra Highway.  My understanding is that the issue stems from how slide prone said segment is. 

[kernals12]

I got a copy of the 1958 San Rafael general plan and it looks like there was a proposal for a freeway parallel to US 101 off the coast of Marin County.

That's all within the City of Rialto, by the way. I think that simply means none of it was officially relinquished yet (the stuff in the County and I think City of San Bernardino should be).

[pderocco]

I drove that hundreds of times when I lived in L.A., and the only place I've actually seen any slide activity is in San Fernando Pass, which has already been relinquished, and that was only a few occasions where a lane had to be closed and some debris swept up, not significant blockages.

I mean hey, I find it a questionable claim also.  But then again why should Santa Clarita or any city accept any old highway simply because Caltrans wants to dump maintenance responsibility?  To my knowledge the state hasn't offered any incentives like they sometimes do with relinquishment agreements.

Well, they should. Perhaps they could install some mesh drapery, because I think the problem is more likely loose rocks than massive collapse.

IIRC the city asked Caltrans to build a pedestrian overpass, but that's all I've seen.

The Caltrans GIS Data page has some stuff I didn't know about just clicking around it. For instance, Route 19 is now completely off the books, while small parts of Route 164 still remain. There are also small portions of former state highways that exist at freeway interchanges including Route 126 east of I-5 still on Magic Mountain Parkway, and Routes 187 and 1 in a couple spots. Also Main Street in Barstow between I-5 and I-40 is designated as part of Route 40, but no S or U.

[ClassicHasClass]

Doesn't CA 187 technically exist *until* LA agrees to take it over?

[Max Rockatansky]

Per the Postmile Tool all that is left of 187 is Venice Boulevard at the ramps to I-10.  For awhile there was a similar necro-highway segment of 225 in Santa Barbara at a ramp to US 101.
