PennDOT will begin preservation work on the Tarentum Bridge from March 15 to mid-April.
Crews will replace deteriorating concrete in the structure underneath the bridge, said Yasmeen Manyisha, PennDOT spokeswoman.
No traffic disruptions are planned.
However, some traffic restrictions are expected later this year when PennDOT works on other bridge repair projects, she said.
The preservation project includes structural steel repairs, painting the structural steel girders, concrete substructure and bearing repairs, expansion dam replacement and repaving a bridge ramp, according to PennDOT.
The agency will repave the westbound lane for traffic exiting to West Seventh Avenue in Tarentum.
Several chunks of concrete fell from the ramp in June 2019. No one was hurt, and no damage was reported.
All bridge repairs are expected to be complete by fall, she said.
PennDOT still is working on the timeline for this year’s work and road restrictions for the bridge, she said.
The agency does not have information yet on the total cost of the project.
About 30,000 vehicles cross the Tarentum Bridge over the Allegheny River daily.
