Big map of Western PA with desired routes drawn in red

(all trips outlined in red... make sure you click the 'Full size' link to the right, see the entire map).
We really enjoyed the trip from Bridgeville on 50 to 18 to 30. We also really enjoyed the red belt. Next, we'll try heading north thru Butler (via Franklin and 528), then west (via 488 and 168) and south, down to Ambridge, and follow the red belt back to Cranberry. (we also loved Frnaklin and 528, hopefully the rest of the route is as good).
Actually, once in Shippingport (on 168), we'll try turning right, and picking up 151 to Ambridge.
