I think work has started on this (or will start soon):I wonder if both Rail Yard Place and the nearby progression of SPMS that Robertee recently documented (re: Infrastructure around Julian Street, etc.) will somehow accelerate the opening of Autumn Street across the RR tracks. This would give quick access to SAP via Coleman Ave. (and 880, etc.).
IIRC, the RR track prep work there is complete (oh, 1-2 years ago), but I don't know if the City of San Jose was waiting for the R/W acquisitions running south (and through the "neighborhood" located to the west of the Guadalupe River Park and Little Italy) to be fully consummated. I think the land is there (ready) north of Julian, but I don't know if the City would green-light the process I speak of unless and until the "end-result" Autumn configuration was ready as a whole.
Info or insights (no pun intended), anyone?
