The whole area of S. Chester Rd (320) from approx. Fairview Rd all the way to Swarthmore College is worse than an obstacle course. There are HUGE potholes that sometimes you just can't avoid because of the traffic on the opposite side of the road. Passed by there this morning, and held my breath that my tires didn't burst. PLEASE address this road soon or you are going to have some very angry drivers with flat tires.
