Unnamed Creek, Tulsa County

Built in 1920, this little pony truss is an excellent example of the adaptability of truss spans. This span has been both moved and widened. Above, a view looking east through the structure. The bridge is a 60-foot riveted Pratt, and features a generous 24-foot wide deck. Notice the original lattice safety railing still intact after 90 years. Below, an elevation-flat side view of the span. This is a standard design bridge popular in the 1920's and 1930's.

Above and Below, these two views show how the deck was widened from 18 feet to 24 by the addition of over 6 feet of extra steel. As you can see the joints where the extra material was welded in was carefully done. The alteration also required adding an additional stringer to each panel. As you can see, the new stringer ins bolted in.

Above,  what you are looking at here is the remains of a stringer approach span that attached to the end of the span. When the span was removed from its original location, the I-beam stringers were simply cut from the angles that attached them to the truss.
