Temporary Detour Vacating Sixth Street In Downtown Pittsburgh, Between Liberty Avenue & Fort Duquesne Boulevard, for Pittsburgh Downtown Partnership & City of Pittsburgh’s Re-Thinking Sixth Street Concept For Restaurants, Beginning in Summer 2020 and Continuing Through September 2021 (Date Subject to Change)

As with the “Re-Thinking Penn Avenue” closure detouring buses for the attempt to provide street dwelling capacity for local restaurants afflicted with internal seating restrictions during the COVID-19 Pandemic, the City of Pittsburgh’s Department of Mobility & Infrastructure (DOMI) and the Pittsburgh Downtown Partnership (PDP) initiated a similar concept called “Re-Thinking Sixth Street” along the same named street, from Liberty Avenue to Fort Duquesne Boulevard. Port Authority was requested to temporarily re-route outbound buses from Sixth Street.

Originally scheduled to end on January 29, 2021, due to the continuing COVID-19 Pandemic and major restrictions on indoor dining at restaurants, the “Re-Thinking” concepts on both Sixth Street and Penn Avenue will be extended again through the late spring, until the middle of May, 2021, with additional temporary infrastructure hardware on both streets, rendering the areas impractical for bus operations.

Port Authority bus routes affected: 7 – Spring Garden, 13 – Bellevue, 15 – Charles, 16 – Brighton, 17 – Shadeland

Second Extension of Temporary Restructuring Of Traffic Lanes (Including Reduction To Single Lane) On Penn Avenue, Between Eleventh & Ninth Streets, for the Pittsburgh Downtown Partnership & City Of Pittsburgh’s Re-Thinking Penn Avenue Concept Through September 2021 (Date Subject to Change)

The Pittsburgh Downtown Partnership has notified Port Authority that it has received a permit from the City of Pittsburgh Department of Mobility & Infrastructure (DOMI) to temporarily close and restructure a two-block section of Penn Avenue in Downtown Pittsburgh beginning Tuesday evening, July 7, 2020. Called “Re-Thinking Penn Avenue”, the concept had been approved to provide additional outdoor seating space on sidewalks and a portion of the street area of Penn Avenue to assist restaurant economies during the COVID-19 Pandemic. The street reconfiguration shifted the Penn Avenue bicycle track and reduced Penn Avenue between Eleventh and Ninth Streets to one narrow westbound traffic lane, weaving back and forth from side to side in order to accommodate restaurant businesses and hotel valet parking. Buses of any type are not desired in the area during the conceptual process.

Enacted Tuesday, July 7, 2020 the original plan was for the campaign to end around October 31, 2020; however, per recent notification, the plan and street restrictions will stay in place, with additional winterization efforts added, until at least January 21, 2021. Second Revision: As the pandemic and restaurant restrictions continue, the City of Pittsburgh has again extended the closure restrictions to approximately May 17, 2021. Said plan will now remain in place until mid-May 2021 but is subject to change based on COVID-19 Pandemic parameters, actual success of the concept and traffic congestion.

Port Authority bus routes affected: 29 – Robinson, 31 – Bridgeville, G31 – Bridgeville Flyer, 86 – Liberty, 87 – Friendship, 88 – Penn, 91 – Butler Street, 2 – Mt. Royal (Weekend Service Only)
