There is no connection from the Ft. Duquesne Bridge to the north east. It's a shame that there didn't seem to be any long term planning of the overarching traffic flows.

It may be gossip and I have no evidence, but my mom played bridge with a woman who worked in the city planning department and was quite a bit older. She said the main planner was a severe alcoholic. Apparently, the city ended up getting help from Robert Moses of NYC (in)famy. Having lived in NYC, I know he is pretty despised and I read the Caro biography which isn't flattering.

However, I also lived in London and the lack of any series traffic planning has dropped the average car and bus speed to horse drawn speeds. I barely drove there and it still was worse than anywhere I've driven.

I just wish there had been a way to provide the road infrastructure in Pittsburgh in a sensitive way. How many junctions on main streets are there in Pittsburgh where the incoming road doglegs half a block or more? There was a point at which things like 28 at Highland Park Bridge and these other problems could've been fixed in a much easier way. I would think by the time government realized the was a problem, there was no money to do anything.
