The Marion Street Bridge is a steel plate girder structure with gothic arched piers. The piers are reminiscent of the 1930ís Conde McCullough era bridges along the Oregon Coast and also that of the St. Johns Bridge in Portland. The bridge utilizes the typical standard steel railing found on Oregon bridges during the era. When the Marion Street Bridge opened in 1953 it was the largest plate girder bridge west of the Mississippi River.
