When will the Port Authority get new buses, particularly ones from the Collier garage? Many are falling apart, are filthy and need brake alignment. Also, the 61 buses from West Mifflin garage are either late during the day or not running — particularly from 1 to 4. p.m. Passengers are packed like sardines, and students from four colleges board along the route, bringing bags, backpacks, shopping bags, etc. The Port Authority needs more buses or backup to this vital region.
