"The Parkway" refers to the expressway that was built in the late '40s and '50s to "modernize" the traffic flow of US 22 (William Penn Highway) and US 30 ( Lincoln Highway) from roughly Monroeville, through Downtown Pittsburgh, and out to the airport. It is formally known as "The Penn-Lincoln Parkway" (kinda catchy, isn't it?). From downtown to Monroeville it's called "the Parkway East". From downtown, across the Fort Pitt Bridge and out to the airport, it is "the Parkway West". Other "Parkways" are bogus.
