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.

Sometimes Google changes the images that it uses which causes the historic image to disappear. The only way to insure that the right image is available in the future is to save it as a photo. Other wise it is at Google's whim that it remains the same image.

Isn't adding a google snap shot redundant when google map is already on the page? Photo's mean photo's.
