Description 

The 100' structure consists of two approximately 20' high verticals fabricated from pairs of laced angles embedded in caissons. Angles set inward at 45 degrees to the tower-verticals are bolted from the tower top to the lower chord; they are counterbalanced by pinned, adjustable cylindrical eyebars also set at 45 degrees and which extend outward to where the lower chord and the concrete abutments meet; and thus the whole consists of two cantilevered kingpost spans joined through an extension of their I-beam lower chords. The inner panel of the longest kingpost has been subdivided to make the top chord more rigid. Designers added a diagonal from the bottom of the pier-tower to the middle of the top chord and an adjoining vertical of a pair of angles. The lower chord supports a 6' timber deck.
