Standing Detour - Emergency Closure Of Smithfield Street Bridge
Begins: 1/1/2026 12:00:00 AM
Ends: 12/31/2026 12:00:00 AM
Summary:
On occasion, the historic Smithfield Street Bridge, a vital link for thirteen (13) Pittsburgh Regional Transit bus routes and four routes for two regional transit agencies (FACT, MMVTA) as well as the bus substitution routing for buses replacing light rail service, when the bridge is compromised, either due to scheduled maintenance or emergencies, must use a lengthy and extensive detour until service over the Smithfield Street Bridge is restored.
Closures could be for heavy maintenance of the bridge by PennDOT or due to emergencies such as excessive flooding of the Monongahela River and high waters or by barge strikes on the piers of the bridge, resulting in concerns for its structural integrity until fully inspected.
This detour will be activated by default, usually by police or emergency forces closing the bridge immediately for emergencies.
