"Nice Wide Lanes And Easy To See Exit Signs"
I-79 going into and in Pittsburgh is a fairly night highway system. It is cut into the mountains/hills, so it could feel closed in and tight; however, because they made the lanes nice and wide with good size shoulders, you do not feel closed in at all. I-79 drives like a boulevard. It rolls with the landscape and, because its so open, the exit signs are easy to see and do not usually sneak up on you as they do on I-279 in the city center. As someone who does not typically like highway driving and avoids it at all costs, I-79 is an easy drive. Please note that I drove it on the weekend and weekdays but never during rush hour.
