1. No loop around Pgh - I have to go east toward Philly frequently and would prefer traveling to Washington, PA and over rather than thru the city. progress on the loop has been at a snail's pace. 2. Entrance and exit ramps share a lane - this is probably the worst traffic problem in Pgh. Whoever designed these ramps is an idiot. If our highways were all 6 lane thruways, it wouldn't be a problem, but with only two lanes on each side, the crisscrossing is very dangerous 3. Mult entrances and exits on the Ft. Pitt bridge/tunnel - There are too many entrance/exit ramps at the Ft. Pitt tunnel/bridge causing crisscrossing on both ends. We need some dedicated highways that don't have to touch down at the Point. 4. There hasn't been a real improvement on the parkways in years. All the construction and delays have only been like "a new coat of paint" - no real improvement in traffic flow. 5. There are no good connectors between the major roadways - 79, 19, 51, etc. people are forced to rely on backroads thru residential areas to get from one point to another.
Traveling that stretch of 376 is bad on any afternoon, not just Friday. And for a town the size of Pittsburgh, "rush hour" should not start at 3:30 in the afternoon.
The northeastern branch of the Mon–Fayette Expressway (576 loop) was indeed planned for an extension to Monroeville, but it seems that whole project has been scrapped.
I definitely agree that the transit system needs a major expansion also. I can't believe there hasn't been any development into the airport area or other major residential areas.
