This thread kind of slipped my mind after reading it. In my state, private contractors do everything from paving and grading to mowing. SO I looked it up for Pa.
Now that you mention it, i did see a beat up grader sitting at the Warehouse restaurant. Theres no way a private individual would be legally permitted to work on a state road, is there?
Well there you go. And no.
From Penndot's website:
Most new highway and bridge construction as well as large-scale repaving projects on PennDOT's state-owned transportation system are done by private contractors, who are awarded contracts following a public bidding process. PennDOT construction engineers and inspectors oversee the
work done by private contractors.
