trail structure

A **trail structure** refers to the designed framework or physical features that support and shape a trail, enhancing its stability, safety, and usability. This can include elements like bridges, boardwalks, retaining walls, steps, drainage systems, and signage strategically incorporated to protect the environment and provide a better hiking or biking experience.
