2) Market Street met up with the Embarcadero in what appears to be some sort of public transportation traffic circle.
It was a big turnaround for Market Street trolleys. I've seen a pic of it at the Pacific Cafe (where Mike dined tonight).
Thanks - do you know when it was 'redesigned'?
My guess would be around the time that they put in the Embarcadero freeway, but I would defer to local history buff TCat for confirmation on that.
Here's an old pic of it taken from in front of the Ferry Bldg., but not the one I referred to above. Still looking for that one.
And here's a postcard from a different angle, closer to the one I'm looking for but still not it.
