A swing bridge is a movable bridge that has as its primary structural support a vertical locating pin and support ring, usually at or near to its center of gravity, about which the swing span can then pivot horizontally as shown in the animated illustration to the right. Small swing bridges as found over canals may be pivoted only at one end, opening as would a gate, but require substantial underground structure to support the pivot.
The Pyrmont Bridge, a heritage-listed swing bridge across Cockle Bay, is located in Darling Harbour, part of Port Jackson, west of the central business district in the City of Sydney local government area of New South Wales, Australia.

Fort Harmar was an early United States frontier military fort, built in pentagonal shape during 1785 at the confluence of the Ohio and Muskingum rivers, on the west side of the mouth of the Muskingum River. It was built under the orders of Colonel Josiah Harmar, then commander of the United States Army, and took his name. The fort was intended for the protection of Indians, i.e., to prevent pioneer squatters from settling in the land to the northwest of the Ohio River. "The position was judiciously chosen, as it commanded not only the mouth of the Muskingum, but swept the waters of the Ohio, from a curve in the river for a considerable distance both above and below the fort." It was the first frontier fort built in Ohio Country.
