Pont de la Machine, Pedestrian bridge over the Rhone in Geneva, Switzerland

Pont de la Machine is a pedestrian bridge over the Rhone, the third bridge downstream from Lake Geneva after the Mont-Blanc and Bergues bridges. Its current iron structure was rebuilt in 1884 (south section) and 1887 (north section) in puddled iron with a timber deck covered in asphalt, making it the oldest civil engineering structure in the City of Geneva. The metal deck rests on four piers on the left bank and three on the right, and the bridge leads to the former pumping station building.

The name comes from the hydraulic machine built in 1709 by Joseph Abeille at the left arm of the Rhone to pump water for the city fountains. A new machine by Jean-Marie Cordier replaced it in 1841, and a wooden footbridge across the river opened in 1844. In 1886 the machine became Geneva's first power station, about 700 kW, supplying electricity until around 1898. The south and north sections of the bridge were rebuilt in 1884 and 1887 in puddled iron with a timber deck.

The former pumping station beside the bridge, now called Quartier Libre, houses a Geneva city information arcade, an exhibition space run by the Services industriels de Genève (SIG) and a café. The name of the bridge itself comes from the hydraulic machine installed here in 1709 to feed the city's fountains.

The bridge is reserved for pedestrians and cyclists, with no motor traffic, and links the left bank to the former pumping station building. Access ramps and a platform over the water were added in the 2007-2009 renovation; the platform was built with a possible future landing stage for the Mouettes genevoises in mind.

In summers 2014 and 2015, to mark the bicentenary of Geneva's entry into the Swiss Confederation, a 900 m² temporary platform held "L'Amarrage", a pool in the shape of the Swiss cross. It was built from nearly 3,000 floating cubes by the TJCA architects' office, with basins 40, 110 and 130 cm deep filled with filtered, heated Rhone water.
