Specifications for Metal Bridges Movable in a Vertical Plane
The excellent paper and specifications for movable bridges by C. C. Schneider, Past-President, Am. Soc. C. E.,* though quite general, pertained mostly to the common swing bridge, or one which rotates about a vertical axis. The writer has felt the need of specifications covering railroad bridges movable in a vertical plane, which necessity was created by the third and fourth track work in progress on the railroad with which he is connected. The common swing bridge is not well adapted to more than two tracks. The writer knows of only two four-track swing bridges in operation.
