Define "suicide"
I used to take 887 from about Clariton to the Waterfront when I lived in Glassport. You'd have to take a lane about half of the way, but I don't think the traffic is too bad. (But this is coming from the guy who takes 885 from Second Ave to West Mifflin everyday)
Once you get to the Waterfront, you have some more suicide options. You can go on through Homestead until you wind up on Carson St (long road, absolutely no shoulder, no room to pass, storm grates to mess with you if you try to hug the curb) or you can walk along a train track for about a hundred yards and be maybe 12 feet away from hundreds of tons steel going 35/40?
