OpenStreetMap
As of yesterday I’ve decided to restart my attempts to improve the mapping of every route in Pennsylvania one by one, from US 1 to PA 999, plus bannered routes and major old alignments, as well as unnumbered routes like the Harrisburg Airport Connector and the Central Scranton Expressway.
So far I’ve completed every numbered route up to and including US 22.
Here’s an example of the sort of sloppy TIGER mapping that gets fixed:

I think this is an excellent idea.
I’m a relatively active mapper from Pittsburgh, and I’ve cleaned up a few whole state routes and significant portions of others. I did the entirety of PA 18, clear from Erie to the border with West Virignia. I also cleaned up all of PA 51 and 68. Partial routes I did include US 30 from PA’s western border to Pittsburgh International Airport, US 422 from Armstrong to the western border, and US 119 from Point Marion in the south almost to Punxatawney.
I’m glad you’re interested in our roads because they desperately need work, especially out in rural areas. Good luck; I hope you finish eventually.
