southwestbound

Southwestbound is a directional term used to describe movement toward the southwest. It is formed from the words "south" and "west" with the suffix "-bound" meaning destined for or moving in that direction. In navigation, it roughly corresponds to a compass bearing of 225 degrees, though in practice it can indicate a southwestern course within a given route or system.

In transportation, southwestbound commonly labels travel directions on railways, roads, and air routes. For example, a timetable might designate a train as southwestbound when it travels toward the southwestern part of its network; road signs may indicate Southwestbound I-5 to guide drivers. In aviation and maritime contexts, flight plans or vessel routes may describe headings as southwestbound to indicate the intended trajectory.

In cartography and logistics, the term helps planners and analysts document movement and plan routes. Southwestbound is part of a family of directional bound terms, alongside northeastbound, northwestbound, and southeastbound. Usage varies by style and region; some sources treat it as a single word, while others hyphenate or separate it as two words depending on the publication standard.
