PUNXSUTAWNEY â€” Representatives from PennDOT District 10 presented plans for work on Margiotti Bridge this summer during a public event Thursday at the Mahoning East Civic Complex.
According to John McCombie, senior civil engineer supervisor-transportation for PennDOT, the scope of the project entails retrofitting certain parts of the barriers on the 75-year-old bridge that spans Mahoning Creek, Water Street and part of the Buffalo & Pittsburgh Railroad.
McCo-mbie said crew will remove open joints on the barriers â€” or the lengths of concrete that prevent pedestrians or motorists from traveling off the bridge â€” that have worn over the years.
The open joints are, at the most about two inches in length, he said. Instead of repairing the joints, the barriers on both sides of the bridge will be replaced with new concrete barriers and rebar.
The project â€” scheduled to begin the second week of June, when school is closed for the summer â€” will entail a partial one-way detour, with northbound traffic being detoured, while southbound traffic will be maintained during the project, McCombie said.
One lane of the bridge will be closed for work on the barrier, while the other lane will be open to traffic traveling south along Route 436. Once the work is completed on the other side, the finished lane will be open to southbound traffic, McCombie said.
Pedestrians will still have access to the bridge during construction, which is expected to last about two months.
