I-710/CA 710 overall history

(1/5) > >>

Max Rockatansky:
We really didn't have a catch all thread for I-710/CA 710.  I decided to take a crack at the insanity/dumpster fire history of the overall 710 corridor:

The Ghostbuster:
It’s too bad the 710 extension to 210 will never be built. While building a tunnel would have been very expensive, it would have been a crucial link in the Los Angeles freeway system. As for the scrapped expansion of existing 710, I would have built the new lanes in a similar fashion to the elevated lanes in the median of the 110 freeway.

At this point, CalTrans should at least relinquish the CA-710 stub and the vacant land south of that from Palmetto Dr to I-210/CA-134 to the City of Pasadena. That's prime real estate that could be developed. Keep the I-210 WB entrance off Pasadena Ave/Walnut Ave.

I thought that was happening as of Jan 1.

Max Rockatansky:
Just deleted the corridor from the Freeway & Expressway System.  A total relinquishment is an entire other matter.

Equally fascinating:

1.  I-710 doesn’t exist per FHWA and AASHTO logs south of Ocean Boulevard or north I-710.  Despite that I-710 is signed in both segments.
2.  The actual acquisition of 710 on Terminal Island by the state is incredibly murky.  It shows up as expressway on the 2005 Caltrans Map before it should have.  So the question I’ve always wonder is, what changed to turn that over from the Port of Long Beach?
