I worked out in Robinson for 4 years. There is absolutely traffic on that stretch of road. I hated working out there for that reason and I barely go out there to shop for that reason.
Also, it may only save 2 minutes FOR YOU. You're one meaningless person on earth. Hell, you probably pass 79 to get to the toll road or drive the opposite direction on 79 to get on it. Imagine if you lived in steubenville and had to commute to southpointe, for instance. Imagine if you lived in Rostraver and took 70-79-376 to get to the airport. Or you worked for a business in southpointe and we're coming from the airport. Or one of the other thousand scenarios that don't apply to you. Not to mention this is just one section of the road that will ultimately be built. You can't even navigate your way through bethel Park, but your opposed to a highway that helps a bunch of people who's only flaw is they aren't you lol.
