Definition - What does Swing Bridge mean?
A swing bridge refers to a rigid architectural structure that revolves around a horizontal plane with a pivot focal point. Swing bridges are less prone to corrosion and degradation if properly monitored.
Corrosionpedia explains Swing Bridge
Swing bridges facilitate the organized movement of both land transportation vehicles and ships on waterways. A portion of the bridge is structurally designed to rotate at a 90-degree angle along its base pivot when boats, ships or other water vessels need to pass beneath the structure.
In 1922, a metal spraying process was designed as a corrosion prevention measure for swing bridges. Metal spraying is a method that protects and extends the life of a wide range of structures and vessels that are usually located in harsh environments and in applications where protective surface coatings are vital for longevity. Marine environments where swing bridges are typically located fit these criteria.
