Lotus Bridge was one of the shortest steel bridges built on the Montour Railroad. This 10 foot bridge was last used on Lotus Siding to span a small creek flowing under Cliff Mine Road and the railroad at trail mile 5.5 in Robinson Township. It was reportedly originally built on the main line in the late 1800's. During a realignment project in the 1920's, a heavier bridge was erected on the main line, and this span was moved and reused when the siding was built. Allegheny County replaced this and two adjacent bridges with a concrete culvert in 2010. Its construction can be seen under the cut-away ties. Larger steel bridges on the railroad were built in similar fashion, with two main girders connected by cross bracing on a larger scale, and the main beams or girders were spaced so the rails and the weight of the trains were directly over these main supports. The Montour Railroad maintained over 80 bridges on 55 miles of track, and many of them are still in use on the Montour Trail.
