Richardson Bridge Portal Bracing

Richardson Bridge (1912) is a rare example of a double-intersection Warren through truss design. A Warren truss (or equilateral truss) utilizes equilateral triangles in its truss geometry for ultimate weight-saving efficiency. This bridge has been moved twice, but remaining within Oregon. Originally built in 1912 over the Crooked River in Crook County, it was relocated in 1956 to a crossing of the Siuslaw River in Lane County, and finally, in 1986, relocated to its current location in West Eugene and converted to a pedestrian-bicycle crossing of Amazon Creek for the Fern Ridge Trail. Partial dismantling for the 1956 and 1986 relocations saw the original rivet fasteners being replaced with modern-era high strength bolts. Notable is the absence of upper lateral bracing. Lane County, Oregon, USA.
