How does this affect my trip? Eastbound buses will operate via N. Ridge, Clark, Ashland, Foster, Broadway, and N. Ridge, ending their trips at Bryn Mawr/N. Ridge. Westbound buses will begin their trips at Bryn Mawr/N. Ridge, then continue their normal route on N. Ridge. Allow extra travel time. Why is service being changed? Buses are rerouted due to construction to improve the Bryn Mawr Red Line station.
