Rehabilitation of the Three Sisters Bridges
Mike Burdelsky, P.E., Allegheny County Department of Public Works, Pittsburgh, PA
The Three Sisters Bridges are perhaps the most iconic bridges in Pittsburgh. This trio of century old bridges have been rehabilitated to ensure that they can serve the residents of Allegheny County for another hundred years. Along with structural steel repairs and concrete deck replacements, the completed projects feature many other improvements including wider travel lanes, separated bike lanes, highway lighting improvements, masonry restoration, and a lighting display to highlight the bridges aesthetic and architecture.
Dark and Dirty Elephant: Rehabilitating the Armstrong Tunnel
Jason Molinero, P.E., Allegheny County Department of Public Works, Pittsburgh, PA
The Armstrong Tunnel is a vital link to Downtown Pittsburgh for both motorists and pedestrians, fulfilling the County’s vision when it was built nearly 100 years ago. In 2022, the Allegheny County Department of Public Works embarked on a rehabilitation project for the tunnel that included structural repairs, cleaning of the stone portals, new tunnel wall lining, a widened sidewalk, new LED lighting system, CCTV, fire detection and suppression and other tunnel life safety features.
2:15 – 3:00 PM; City of Pittsburgh
Rapid Response Engineering – The Race to Rehabilitate Pittsburgh’s Historic Charles Anderson Bridge
Aaron B. Colorito, P.E., Michael Baker International, Moon Township, PA; Zachary Workman, City of Pittsburgh DOMI, Pittsburgh, PA
The 1939 Charles Anderson Memorial Bridge is a historic, three-span Wichert deck truss bridge spanning over two railroads to connect the City of Pittsburgh’s Oakland neighborhood to Schenley Park, a Section 6(f) resource. A rehabilitation project was in the preliminary engineering phase when an update to the structure’s load rating analysis prompted an immediate closure to all vehicular traffic.
This presentation will briefly introduce how Asset Management has evolved in the City following the 2022 collapse of the Fern Hollow Bridge, the ramifications of this program (including what lead to the closure of the subject bridge), and the extraordinary effort to deliver almost two years of anticipated engineering effort in just eight months (plus incorporating an adjacent simple-span superstructure replacement for an added challenge).
