the.com/suspension bridge

means A bridge whose deck hangs from cables that drape between towers and anchor into the ground, so the road rides on tension instead of resting on piers below.

from 'Suspension' traces back to Latin suspendere — 'to hang up' (sub- 'under' + pendere 'to hang' or 'weigh') — the same root behind 'suspend' and 'pendant.' The engineering idea has ancient roots too: simple rope-and-vine suspension bridges existed in places like the Himalayas, the Andes, and China long before the term was formalized. The modern phrase 'suspension bridge' came into English use as iron-chain and then steel-cable designs were engineered in the 1700s–1800s, giving an old hanging-rope trick a new name in steel.
