This railroad deck truss has an unusual design. Look at the photo to the right, taken standing under the bridge. On the right side of the bridge, there is a typical truss line, composed by a single set of built-up beams. However, on the left hand side, the truss line is twice as massive. It has the appearance of two truss lines side by side, since rather than a single beam, there is a pair of built-up beams for the top chord and bottom, chord. The truss members are also designed like a pair of beams, however the vertical members are connected by riveted plate so technically this cannot be described as two truss lines, it appears to function like a single truss line. The reason for this unusual asymmetrical design may have been due to the fact that this bridge was designed to be widened some time in the future after it was completed. This can be evidenced by the overly wide abutments which have room for another superstructure. The plan with this bridge may have been to build another truss superstructure identical (including the asymmetrical details) to the existing one. When erected, the smaller truss lines on each structure would be combined to form the heavier "double" truss design like that seen on the outer edge, thereby forming a single superstructure composed of three "double" truss lines. The bridge was never widened however, so it retains the unusual design today, which can be easily viewed and appreciated by anyone walking on the rail-trail that passes under the bridge.
