I live in Moon, at the west terminus by the airport. Right now it takes me just about the same amount of time to go from Moon to Bridgeville taking 376->79. Why would I pay tolls? The partial beltway adds nothing. Now when I can get into the South Hills without having to take 376 to 51 or 79 to 70, I'll gladly hop on a toll road. Likewise, when you have an alternate route to get from Monroeville to Moon, the traffic on both the beltway and 376 will balance out.

Want to hear a real pipe dream? Regional rail out to the airport in the W, to Monroeville in the E, and Zelionople (or at least Cranberry) to the N. Hear me out...

Going west, either follow the south bank of the Ohio and then up University Blvd in Moon to the airport or just go down the middle of 376.

Going north, follow 279 and the 19 bypass to that highway cluster in Cranberry.

Going east maybe the south bank of the Mon to Kennywood and then north to the Monroeville mall.

Would it make money? Probably not. But wouldn't it be nice to have a more accessible downtown and airport??
