Description 

This unique span featured two horizontal members in each truss. The top one ran through the verticals and then up into the upper chord/endpost connection where it was likely adjustable. The lower one ran to each outer vertical and may or may not have been adjustable. This is the first time I have seen two sets of these on a bridge.
