if you think 78 is bad, in Pittsburgh you have I-279 which goes over the fort duquense bridge. It's 4 lanes of people criss-crossing going from one lane to the other, kinda looks like a ballet. You don't go through that at 70mph unless there is no traffic, it is just too dangerous. but just a few hundred feet away you have Pa-65 merging from the left onto I-279N and you have to pray that there isn't anyone in the left lane when you merge, and if you are trying to get to 28N you have to cut across both lanes to do it. It sucked to begin with, but now they have added a parking garage which obstructs your view of the oncoming traffic (as if you had a view to begin with) It's so unsafe that I actually avoid it whenever possible. And since it is a curve you can't even go slow on it because you can't see the people coming at you until they hit you. Just an overall bad design.
