Blue line: how many times has it been promised?

Faiz Imam linked this twitter thread in a comment below, but I’m bringing it up to the top here because it’s worth seeing: Steve Faguy’s list of the repeated political announcements of money for the blue line extension, an unfulfilled promise made every few years since 1985.

Update: With Steve’s permission I’ve turned his twitter thread into a permanent timeline page linked to my sidebar.

Another point about the extension: hasn’t excavation and tunneling technology advanced at all since the 1960s? Shouldn’t digging five stations be faster and more efficient now than it was between 1962 and 1967, when 26 stations were built and opened?
