[Many of the images show the stresses calculated for each member of the truss.]
Pictures are of the original Stress sheet of the P&LE cantilever bridge at Monaca - Beaver PA . Appears to be drawn on vellum type paper using a ink well pen. All of the math about the bridge is here. Live load,dead load, impact load and wind load Date is Jan. 31, 1908. Bought this on eBay around 20 years ago. Was unaware at the time of purchase of what I was getting. Wow, when I actually received it. Total calculated design load on one of the main bearings is 11,994.000 or 12 million pounds or ( 6 thousand tons).

Mark Arnold posted five photos with the comment: "CSX's Ohio River crossing between Monaca and Beaver Pennsylvania."
Pedro RamosPedro and 757 others joined RAILROAD BRIDGES, TRESTLES, TUNNELS AND CUTS within the last two weeks. Give them a warm welcome into your community! Wow makes you wonder how were they ever able to build a massive structure like this.
Dennis DeBruler One of the reasons for building cantilever designs is that it allows minimal interference during construction in the navigation channel. Typically, they would use timber falsework to build the trusses between the abutments and piers. Then they would use travelling derricks along the top chords to build the other sides with minimal falsework. I found some construction photos for a bridge: But the top chords on this bridge have a very steep angle, so I don't know if they could have used a travelling derrick.

"Bicentennial" liveried Pittsburgh & Lake Erie #1501 makes a splashy entrance to Beaver PA as it comes off the big P&LE bridge over the Ohio River with the westbound afternoon Pittsburgh to Beaver Falls (College) commuter train.  The weekday train was the last surviving remnant of a once robust passenger train service over P&LE rails, between Pittsburgh, Youngstown and, via the Erie Railroad, Cleveland.  May, 1976 photo by Mark Hinsdale

CSX Q331 passes over the ex P&LE Beaver Bridge to continue it’s journey West towards New Castle, PA. The tracks below are the NS the Cleveland Line and in the distance to the left, are the tracks for the NS Fort Wayne Line. Enjoy!
