Work on the Yaquina Bay Bridge began on August 1, 1934. The bridge opened on September 6, 1936,[1] at a cost of $1,301,016 ($28,570,000 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 70 feet (21 m) below sea level. The project received funding from the Public Works Administration.[4]
Description
The 600-foot (180 m) main span is a semi-through arch, with the roadway penetrating the middle of the arch. It is flanked by identical 350-foot (110 m) 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.[5][6] The arches are built as box girders. The two-lane road is 27 feet (8.2 m) wide, running inside the arches with two 3.5-foot (1.1 m) sidewalks. The main arch is 246 feet (75 m) above sea level at its crown. Overall length of the bridge is 3,260 feet (990 m), including concrete deck-girder approach spans. The navigable channel measures 400 feet (120 m) wide by 133 feet (41 m) high.[4]
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.
