This bridge is an unusual example of a truss bridge using bolted connections for all field-attached connection points. Its design is very similar to an average truss bridge from the period with riveted connections, except that there are bolts holding the members to the gusset plates.
During the late 1800s, pinned connections were the most common form of connection used on truss bridges because field riveting equipment and skilled labor was not available to erect the bridges on-site using riveted connections. Bolts were used sparingly, generally only to assemble segmented pieces of the larger shop riveted beams together, such as the top chord. As the 20th Century rolled around and field riveting became available, then riveted connections became common, and rivets were used for mostly everything until the 1960s. As such, bolted connections did not become overly popular until the 1970s.
Otherwise, the bridge is traditionally composed, although the top chord and end post is a rolled beam rather than built-up.
