The City of Pittsburgh's Department of Mobility and Infrastructure (DOMI), in conjunction with PennDOT District 11 and the Pittsburgh Downtown Partnership, have announced their intention to close a portion of Smithfield Street and the Smithfield Street Bus Lane in the Downtown area of Pittsburgh beginning Monday, September 21, 2026.
The closure is required to allow contractors to perform full street reconstruction including the roadway, curb and sidewalk improvements related to the city's Smithfield Street Reconstruction Project.
Beginning with the start of service on Monday morning, September 21, 2026, Smithfield Street and the Smithfield Street Bus Lane between Oliver and Fifth Avenues will be closed. Once closed it is estimated the block will be closed for approximately two months before shifting to the following block, between Fifth and Forbes Avenue when the P12 Holiday Park Flyer, P16 Penn Hills Flyer & P67 Monroeville Flyer will be returned to regular route.
The overall project, which will alternatively close Smithfield Street between Sixth and Forbes Avenues, is expected to continue for approximately two (2) years and will require additional detours as the project progresses.
Start: 09/21/2026 — End: 09/21/2046
