Description 

The Necanicum River Bridge on Broadway Street in Seaside is the only known patented Luten arch in Oregon. The design and construction methods devised by Daniel B. Luten, a consulting engineer from Indianapolis, were widely used nationwide between 1910 and 1930. The ornate concrete deck arch consists of three 41-foot filled spandrel, barrel type sections with integral approaches. The bridge contains decorative urn-shaped balustrade railings and lampposts. A south side monument pedestal contains a bronze bas-relief, “Old Oregon Trail” by noted Oregon sculptor Avard Fairbanks. The companion north pedestal features the “Lewis and Clark, Salt Works” bronze relief.
