The Yaquina Bay Bridge is an arch bridge that spans Yaquina Bay south of Newport, Oregon. It is one of the most recognizable of the U.S. Route 101 bridges designed by Conde McCullough and one of eleven major bridges on the Oregon Coast Highway designed by him.<ref>Template:Cite book</ref> It superseded the last ferry crossing on the highway.

History

Work on the Yaquina Bay Bridge began on August 1, 1934. The bridge opened on September 6, 1936,<ref name="oreg1936sep6">"Span at Newport Open For Traffic" (September 6, 1936). The Sunday Oregonian (Portland), pp. 1–2.</ref> at a cost of $1,301,016 ($Template:Inflation in today's dollars). A total of 220 people worked to pour 30,000 cubic yards (23,000 m³) of concrete and fabricate 3,100 tons of steel. The contractors were the Gilpin Construction Company of Portland, Oregon, and the General Construction Company of Seattle, Washington. The main arch was built in toward the center from the anchorages, using tiebacks to support the arch until it could be closed. The piers are supported by timber pilings driven to a depth of about Template:Convert below sea level. The project received funding from the Public Works Administration.<ref name=nrhpnom1>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref>

Description

The Template:Convert main span is a semi-through arch, with the roadway penetrating the middle of the arch. It is flanked by identical Template:Convert steel deck arches, with five concrete deck arches of diminishing size extending to the south landing. The main arch is marked by tall obelisk-like concrete finials on the main piers, with smaller decorative elements marking the ends of the flanking spans.<ref>Template:Cite book</ref><ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref> The arches are built as box girders. The two-lane road is Template:Convert wide, running inside the arches with two Template:Convert sidewalks. The main arch is Template:Convert above sea level at its crown. Overall length of the bridge is Template:Convert, including concrete deck-girder approach spans. The navigable channel measures Template:Convert wide by Template:Convert high.<ref name=nrhpnom1/>

The bridge uses Art Deco and Art Moderne design motifs as well as forms borrowed from Gothic architecture. The Gothic influence is seen in the balustrade, which features small pointed arches, and in the arches of the side span piers. The ends of the bridge are augmented by pedestrian plazas that afford a view of the bridge and provide access to the parks at the landings by stairways. Pedestals were provided for proposed sculptures of seals, but the statues were never executed.

Designation

The Yaquina Bay Bridge was placed on the National Register of Historic Places on August 5, 2005.<ref name="nris"/>
