One kind of movable bridge is a swing bridge.

	While a swing bridge in England is defined under [https://www.legislation.gov.uk/ukpga/1980/66/section/329 Section 329 of the Highways Act 1980] as, “...any opening bridge operated by mechanical means”, this broad interpretation would include other mechanised opening bridges, such as certain types of drawbridges, lift bridges, retractable bridges and so on. For clarification, a swing bridge is a movable bridge with a deck that rotates around a fixed point, in some instances working in a similar way to a gate.

−	Initial designs for the Swing Bridge were drawn up in the 1860s by John Ure, the resident engineer of the Tyne Improvement Commission.

	The bridge, which requires approximately six minutes to complete a full rotation, underwent a significant renovation in 2018. However, Armstrong’s hydroelectric powered engineering mechanisms have been kept in working order and still operate as originally designed.

It will have a twin-leaf design - making it a double swing bridge - with each leaf opening and closing horizontally.	+	In March 2021, plans were announced for a new swing bridge over the River Clyde.

When the swing bridge is closed, road or rail traffic can travel freely over the waterway. For busy roads, this is often the default position.

	When water traffic needs to pass through, traffic signals or barriers are activated to prevent road traffic from crossing. The bridge is then mechanically activated so it swings or pivots into place, allowing sufficient space and time for boats, barges and other watercrafts to pass through the channel (or channels) safely.
