We've talked with PennDOT time and time again on this. Since their mission is safety first, and sometimes safety only, PennDOT loves the white line runble strips.
We've tried to work with them to stress the importance of maintaining bike access to the shoulder by breaking the rumble strips at regular intervals. I assume that was done on Saxonburg Blvd? Can you get to a shoulder that is safe to ride on at all?
