Description 

The Stark Street Bridge is a two span steel truss structure built in 1914 across the Sandy River off of the Historic Columbia River Highway near Troutdale, Oregon. The 200-foot main span consists of a ten panel Parker through truss with built-up riveted members. The south approach span is a 77.5-foot polygonal Warren pony truss with verticals, which is also made from built-up riveted members. The bridge carries a narrow 18-foot roadway which funnels two lanes of traffic over the river.

The bridge was not originally designed with pedestrian facilities, but a timber sidewalk was added to the east side of the structure during the 1990ís. The original guardrail for vehicular traffic is a riveted lattice railing which was popular on truss structures in Oregon during the decade between 1910 and 1920.

The bridge was designed by Karl P. Billner of the newly formed Bridge Section of the Oregon State Highway Commission under the supervision of state bridge engineer Charles H. Purcell. Contractors George H. Griffin and the Portland Bridge Company completed the onsite construction of the bridge, while the American Bridge Company fabricated the steel truss spans.
