The Van Buren Street Bridge in Corvallis is Oregon's only remaining movable bridge built with rare pin-connected truss technology, using pins or bolts at each truss point so the structure could be assembled on site after fabrication elsewhere. Designed in 1912 by Portland engineer Andrew Porter of Coast Bridge Company and completed in 1913, the steel swing bridge was Corvallis' first bridge across the Willamette and served as the city's only river crossing until the nearby Harrison Street Bridge was built in 1964. Its 249-foot main span pivoted on a circular roller track atop a central concrete pier, and six men using a 17-foot wooden turning key could rotate the span to open 102 feet of clear passage for boats; the bridge last opened for river traffic on October 5, 1960. Costing $63,000 and funded mainly by Benton County with contributions from Linn County, private citizens, and the City of Corvallis, it carried two-way travel on a 20-foot roadway with a 6-foot wooden sidewalk on the south side. The site had been a regular river crossing since the 1850s, when Isaac Moore's ferry carried people, goods, and livestock between Benton and Linn counties for 85 cents round trip, and Benton County bought and operated the ferry as a free crossing from 1902 until the bridge opened. Residents celebrated the bridge's opening on March 11, 1913, with a parade of officials, citizens, a military band, teachers, school children, horses, and the Fire Department. In a fierce windstorm on January 25, 1914, loosened gravity latches allowed the wind to blow the swing span off its shoes while local boy George Way was crossing, and boat tenders reached the bridge and closed it, bringing him to safety. The bridge is also the point where Corvallis' official Willamette River levels are measured: 16 feet is bankfull, 20 feet is flood stage, 21 feet closes Highway 34 to vehicles, and 27 feet is a major flood. The greatest flood after European settlement of the Willamette Valley came in the winter of 1861, when the river crested at 34.4 feet on December 1, 1861, destroying the nearby town of Orleans that Isaac Moore had founded in the 1850s. Construction also faced political dispute in 1912, when protests from north Benton County threatened delay until Corvallis residents voted to provide $2,500, and on November 22, 1912, Ida Hodes became the first woman to vote in Corvallis on the successful bridge funding measure after women won voting rights in Oregon.
