This massive 2-span pin-connected Pratt pony truss bridge carries an active railroad over the Milwaukee River. The abutments on this bridge are perpendicular to the railroad, while the center pier is skewed to match the angle of the river. As a result, the end posts of each span at the center pier are not parallel to each other, with one being longer than the other. These truss spans are enormous; the end posts and upper chords are extremely wide, and the diagonal tension members are very thick and feature gigantic turnbuckles for tension adjustments. The trusses are as tall as some highway through trusses, and lattice is on the lower chord and under the upper chord. The verticals are built-up with plate steel rather than battens or lacing.
