Suspension Bridge Structure Explained - Main Cable, Deck, and Caissons #3631772 (License: Personal Use)

This schematic illustrates the core structural elements of a suspension bridge: the curved main cable that carries tension, the horizontal deck (tablier) supporting traffic, and the submerged caissons that anchor the towers into the riverbed or seabed. The caissons provide critical vertical support and resist lateral forces, while the main cables transfer loads to the towers and foundations. The diagram emphasizes engineering principles behind long-span bridge design.

Used in civil engineering educational materials, infrastructure project documentation, or transportation infrastructure webpages; targets students, engineers, and curious readers seeking to understand bridge mechanics.
