If the bridge deck is carried along the bottom of the truss (called a through truss) or if a lightweight lower chord is present, identification is made solely by the multiple diagonal members emanating from the end post tops.Īn Inverted Fink Truss has a bottom chord without a top chord. This gives the bridge an unfinished saw-toothed appearance when viewed from the side or below, and makes the design very easy to identify. Many Fink trusses do not include a lower chord (the lowest horizontal member). These diagonal members extend to the bottom of each of the vertical members of the truss with the longest diagonal extending to the center vertical member. It is identified by the presence of multiple diagonal members projecting down from the top of the end posts at a variety of angles.
