We have that sort of thing in random places; There are 3 lane stretches on US22 between Pittsburgh and Altoona, and then scattered further east across the state. It's ok, if the zones are long enough. Otherwise it's "tromp it, see how much you can get around, slow down, wait" and sometimes someone else pulls out to pass and is in no hurry. It's worse when there are hills involved, which is often.

Thankfully, since I got my license in 1989 they've been upgrading this to 4 lanes divided. It also connects near Altoona with a nice north-south highway, US220 (also known as I-99. what a travesty) which they're extending north. Can't wait for that to be done.
