Wind load on a bridge structure is considered a primary live load.

Explanation:
Wind load on a bridge is not a live load. Live loads are the loads that come from traffic and occupants—loads that move across the structure during its service life. Wind is an environmental (external) action that comes from weather and can vary independently of traffic, often requiring separate analysis for static and dynamic effects (gusts, vortex shedding, buffeting). Because wind is categorized as an environmental/dynamic load, not a live load, the statement is false.
