All the construction happened while I was living in San Francisco. On a trip home in 1994 my mom couldn’t wait to show me, and all but demanded we take a drive downtown. At the time I wasn’t impressed; after all, it seemed like the tunnel through Yerba Buena island for I80/Bay Bridge was longer. Knowing now what went into the construction definitely impresses me for its sheer engineering prowess.
I’ve also had the pleasure of visiting the control center to replace some PCs while I was working for ADOT. I had no idea how complicated the entire system was, so I definitely came away with a newfound appreciation for what went into it.
