沿线

• Pinyin: yán xiàn
• Hanzi breakdown: 沿 = 氵(water) + 㕣 (following a course); 线 = 糸 (silk/thread radical) + 泉 (spring — originally suggesting a continuous filament)

Meaning

Along the line; along a route. Refers to areas, places, or conditions distributed along a linear path such as a railway, highway, pipeline, or border.
