Stark Street Bridge

The Stark Street Bridge is a 277-foot (84 m) steel truss bridge spanning the Sandy River near Troutdale, Oregon. It connects Southeast Stark Street with the Historic Columbia River Highway and serves as one of only two western entrances to the highway. Designed by Karl Billner under the supervision of State Bridge Engineer Charles H. Purcell and overall construction oversight by Samuel C. Lancaster, the bridge replaced an old wooden structure that collapsed on April 25, 1914, during Good Roads' Day.

The new bridge, described in a 1914 report by Oregon State Highway Engineer Henry Bowlby, features one 200-foot riveted through Pratt camelback steel span and one 77-foot Warren pony steel span. It has a reinforced concrete slab floor with creosoted wood block pavement. The bridge provides 35 feet of clearance above low water and includes bitumen-filled expansion joints in the concrete slab over each floor beam. The clear roadway is 20 feet wide, designed to accommodate live loads such as four 20-ton trucks in line or two passing 20-ton trucks.

Constructed by contractor George H. Griffin, the bridge was completed on January 10, 1915, at a cost of $21,042.40. It is documented by the Historic American Engineering Record (HAER) and is noted for its design and historical significance.
