Pittsburgh will restrict the 28th Street Bridge, which connects the Strip District and Polish Hill, to a single lane of traffic beginning tomorrow, November 3, 2026. The restriction follows a Tuesday inspection and is expected to become a long-term inbound-only limit.
Why it matters
The bridge's deck, substructure and superstructure are rated "poor" in a PennDOT database, and the city is preparing to refurbish the aging structure. The change will reroute outbound drivers, the southern sidewalk is closed, and Pittsburgh Regional Transit buses are adjusting their outbound routes.
The 315-foot 28th Street Bridge opened in 1931, and its deck, substructure and superstructure are each rated "poor" in a PennDOT database. The engineering design work is contracted with PennDOT oversight, and the scope of the refurbishment and its cost remain unannounced.
The players
Department of Mobility and Infrastructure
The city of Pittsburgh agency that inspected the bridge and ordered the lane restriction and detour.
Pennsylvania Department of Transportation (PennDOT)
The state transportation agency that maintains the statewide bridge condition database and provides oversight for the refurbishment design.
Pittsburgh Regional Transit
The regional public transit agency whose buses cross the bridge and are adjusting their outbound routes.
The details
The Department of Mobility and Infrastructure will limit the bridge to one lane starting tomorrow, with outbound traffic directed to Liberty Avenue and Bigelow Boulevard via the Bloomfield Bridge. Pittsburgh Regional Transit buses will continue inbound crossings and take an outbound detour via Herron Avenue to serve 54D stops.
Timeline
Tuesday: Department completes inspection that prompted the lane restriction.
November 3, 2026: Single-lane restriction on the 28th Street Bridge begins.
2028: Refurbishment work is expected to start.
2030: The bridge is expected to reopen.
Business Strategy Context
The city's approach mirrors the state's bridge management process, in which PennDOT's condition ratings trigger local refurbishment planning under state oversight. The 2028 start and 2030 reopening timeline places the project in the multi-year capital planning cycle used for aging urban infrastructure.
Drivers heading outbound from the 28th Street Bridge will need to use the Liberty Avenue and Bigelow Boulevard detour via the Bloomfield Bridge. Bus riders on the 54D route should expect an alternate outbound path via Herron Avenue while the single-lane restriction is in effect.
The takeaway
Commuters who cross the 28th Street Bridge should plan for inbound-only access and allow extra time for the outbound detour. Watch for updated restriction details as the refurbishment schedule approaches.
What happens next
Refurbishment design work is expected to proceed under PennDOT oversight, with construction projected to begin in 2028 and the bridge reopening in 2030.
