To celebrate the 100th anniversary of the Mountain Quarry RR out of Auburn, CA the last of the railroad engines, a Porter 0-4-0T was hauled out and placed on the "no Hands bridge". The bridge is a 75ft high concrete bridge built by the Mt Quarry RR in 1912. It is one of the first reinforced concrete railroad bridges and has withstood several floods including one that took out the highway bridge just upstream.
