| One of 26 images posted by Mike Brady [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). |

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: http://industrialscenery.blogspot.com/.../csxc-1917.... 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.

| Mark Hinsdale posted Sunday Night @ the Oldies "Red, White & Blue" "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.

| Jamie Adams posted Chessie/B&O #4106. - The location or photographer aren't mentioned on the slide mount, unfortunately, but the color of the trees, the way the image is composed, and the subject matter make this one, one of my favorites amongst the others. - Kodachrome slide. October 1981. Collection of J.L. Adams. John Rompala: P&LE Bridge, the photo was taken from the Signal on #2 Track on the Monaca side of the Ohio River, MP PLE 25. |
