A Guthrie rolling bridge was a kind of retractable bridge, an 18th century version of the drawbridge. It was commonly installed as the access across the narrow steep sided ditches characteristic of the polygonal forts of this era.
Rolling bridges were unhinged, and remained horizontal as they were retracted within the gates of a fortification, similar in operation to a modern thrust bridge.

“This land is your land, this land is my land, From California to the New York Island. From the redwood forest to the Gulf Stream waters This land was made for you and me.”

This Merrimack was neither rivus nor fluvius nor lacus, but rather amnis here, a gently swelling and stately rolling flood approaching the sea. We could even sympathize with its buoyant tied, going to seek its fortune in the ocean, and anticipating the time when “being received within the plain of its freer water,” it should “beat the shore for banks.””
—Henry David Thoreau (1817–1862)
“Home! Yes! she would see Trafalgar Square, again; and Nelson on his plinth; and Chelsea Bridge as it dissolved into the Thames at twilight ... and St. Paul’s, the single Amazon breast of her beloved native city.”
—Angela Carter (1940–1992)
