Pressure-treated timber was a main element in the bridge which spans 18 feet at a height 100 feet above the San Joaquin River Gorge. Approximately 11,600 board feet of Douglas Fir weighing three and one-half tons was used. The decking was treated with penta preservative in light petroleum solvent and stained green. The deck tread was made up of 3x12 by 8-foot timbers spiked to 6x14 stringers, which are bolted to the steel bridge structure with galvanized bolts. The bridge provides a 6-foot wide passage between handrails. The contractor transported his materials to the site and across the river by a system of highlines.
