enjamber

To step over something in one stride — enjamber une flaque, une barrière — or, for a bridge or structure, to span across something (le pont enjambe la rivière). A common, concrete verb for both people and structures.

• Elle a enjambé la flaque d'eau sans se mouiller. — She stepped over the puddle without getting wet.
• Le pont enjambe la rivière sur près de deux cents mètres. — The bridge spans the river for nearly two hundred meters.
• Il enjamba la barrière pour couper par le champ. — He stepped over the fence to cut across the field.

Learners often reach for traverser (to cross) for everything, but enjamber specifically means to step or stride over something in one motion — not to cross a larger distance, which is what traverser is for.
