Mirror highway junctions

I recall posting this photo of the Four-Level (from Eric Fischer's archive) a while back:

It doesn't clarify if US 70 started at the Four-Level, but that spot on US 101 (at the start of the Santa Ana Freeway) is probably the westernmost sign for it that ever existed.

(One could argue that the usage of US 70 signage this far past the San Bernardino Split is similar to today's Caltrans usage of US 101 signage on I-80 west between the foot of the Bay Bridge and I-80's terminus at the Central Freeway in San Francisco.)

I had forgotten about that one.  but yes, it stands to reason to sign US-70 from just a mile or so away from the East LA.

by that time it looks like 60 was gone.

I remember us discussing that at length some time ago - assuming the pre-1964 situation, and assuming that there were no Interstates in the area at the time of this photo (otherwise, we'd see the situation that exists today, of I-5 advanced signage from the Four-Level onwards on 101)...

1. Did 60 even ever reach the Four-Level?  (The sign the 70 shield covers up is a 99, which I assume at this point was on the Golden State Freeway)
2. Was 60's west end until 1964 always at 101, whether at the existing San Bernardino Split, or at the proposed East Los Angeles Interchange?

no idea, as the original San Bernardino Split was built before the Four-Level.  Mike Ballard says the two went to the Four-Level, but I've seen it only signed to the San Bernardino Split.

2. Was 60's west end until 1964 always at 101, whether at the existing San Bernardino Split, or at the proposed East Los Angeles Interchange?

no, it was truncated by 1959 or 1960 to what is currently 71@10. I have maps showing only 70/99 on the San Bernardino Fwy.

U.S. 60 continued to be posted along the San Bernardino Freeway from Pomona to downtown L.A. until the 1964 renumbering. The format of the signage indicated that the Division of Highways was preparing to move the route to the Pomona Freeway; there were assemblies of I-10/U.S. 70/U.S. 99 shields on one post or light pole, then a lone U.S. 60 shield on another light pole nearby. After U.S. 99 was moved onto the Golden State, the overhead signage at the San Bernardino/Golden State interchange inbound to L.A. was changed to U.S. 70  - the only time I remember seeing any suggestion that U.S. 70 might ever exist other than as a concurrent route. After 1964 that shield was replaced with U.S. 101.

wow, that is the first time I had heard of that!

I had seen somewhere a photo of a 10/70/99 with no 60, and also the maps... I'll have to find the 10/70/99 to see if there is a 60 lurking in the background

Personal observations. We roadgeeks start young.

Would 540/ 45 count? 

I-540/AR 45 in Ft Smith.

it would if they both were the same type of route. I vs state doesn't count.
