As part of the agency's regular four-time yearly schedule adjustments, more than 70 Port Authority bus routes will see changes on Sunday.

Approximately 45 bus routes will be adjusted. Among the changes are tweaks to routes affected by the ongoing weight restriction on Swissvale’s Kenmawr Bridge, as well as changes to better serve Bedford Avenue in the Hill District, according to the agency.

Port Authority will also begin bus-stop consolidations. Nearly 430 stops that see little to no use will be eliminated Sunday.

Details on the service changes and links to new schedules are now posted at www.portauthority.org under “Service Changes" and are available here.

Paper schedules will be available prior to the changes.
