Engineers from Michigan Army National Guard’s 1437th Multi-Role Bridge Company, based out of Sault Saint Marie, Mich., wait as a Chinook from B Company, 3rd Battalion, 238th Aviation Regiment, based out of Grand Ledge, Mich., makes an aerial delivery of sling loaded components for an improved float bridge, also known as a ribbon bridge, on the St. Mary’s River.
