Morphology

transmountain = mountain (transparent) = trans + mountain

The word is transparently built from the prefix 'trans-' meaning across and the noun 'mountain', so the meaning of something crossing mountains is easy to infer.

Etymology

Transmountain comes from trans- ('across'), the same prefix you see in transport, and mountain ('mountain'), so it literally means a way across a mountain. That's why a transmountain is a road, tunnel, or passage that crosses a mountain or mountain range.
