I am going to rent a car to drive to Falling Water this Monday. I will be staying at the Marriott City Center and renting from a nearby Hertz location.
I will leave downtown Pittsburgh around 9 am, maybe a little earlier and return probably between 4 and 5 pm. I have mapquested the route and I'm good with directions, so I'm not worried about that, but I am wondering how bad traffic is likely to be at that time.
I will head east on 376 to Monroeville and back west on that route probably after 4 pm. How bad is traffic likely to be at that time?
