Bridge Le Pont de Carouge, Road and tram bridge in Carouge, Switzerland

The Pont de Carouge is a road and tram bridge that crosses the Arve River and links the two municipalities. Its stone construction supports vehicle and tram traffic along with pedestrian pathways on both sides.

Bridges have existed at this crossing for thousands of years, but the current structure dates to the early 1800s. The design was later adapted to accommodate expanding traffic and new transportation systems.

The name Carouge derives from the Latin Quadruvium, referring to the road fork south of the Arve crossing, and the bridge long marked the border between the Duchy of Savoy and Geneva. Since 1862 the bridge has carried the Geneva tram: the Geneva–Carouge line of the Compagnie générale des omnibus was Switzerland's first tramway, and lines 12 and 18 still cross it today.

Tram lines 12 and 18 of Geneva's network cross the bridge, and the Rue du Pont Neuf and Place de l'Octroi lead to it on the Carouge side. No main road runs over it today; traffic uses the Pont des Acacias (1955) and Pont de Saint-Georges (1882) downstream. The deck was rebuilt in 2016 but could not be widened, as the cantonal monuments commission refused.

For several decades, the structure served as a key monitoring station where scientists measured and recorded water flow in the Arve River. This data helped track changes in the river over time.
