Cadets pose after constructing a temporary bridge across the Marys River, ca. 1920. The proximity of the Marys River to the OAC campus made it a suitable location for this type of military exercise. The more permanent 3rd Street bridge is in the background.
Military engineers, 1925. Building a standard pontoon bridge while on training manoeuvres. This photo appears to be a stock issue for publication in OAC yearbook or Oregon Stater, circa mid-1920s. Reprint in this format is from later date, with stamp on reverse: "Department of Information, Oregon State University, Corvallis, Oregon." Activities include cadets moving floating bridge components up to bank and building plank roadway. Military caterpillar tractor is pulling supplies to location. Cadets in uniforms and civilian onlookers on bank of river (probably Calapooia).
