The St. Johns Bridge is a steel suspension bridge that spans the Willamette River in Portland, Oregon, USA, between the St. Johns neighborhood and the northwest industrial area around Linnton. It is the only suspension bridge in the Willamette Valley and one of three public highway suspension bridges in Oregon.
