Pont de Jons, bridge in France

Pont de Jons is a road bridge carrying the RD 61 across the Rhône between Niévroz and Jons, just upstream of where the river splits into the Miribel and Jonage canals. It is a box-girder bridge with a prestressed concrete deck 200 metres long, in three spans of 55.07, 90 and 55.07 metres. A sign on the guardrail reads "Le Rhône".

A first bridge stood here until 1904, when it was replaced by a suspension bridge inaugurated on 20 October 1904. That bridge was dynamited in 1940 during the Battle of France; a temporary bridge installed by the Germans was destroyed in 1944. From 1944 to 1977 a single-lane metal bridge controlled by a traffic light carried the crossing, and the current bridge was inaugurated in May 1977.

The bridge is used daily by vehicles, buses, and pedestrians and offers good views of the surrounding landscape. Access is straightforward, and visitors can cross on foot or by bike.

Just downstream from the bridge lies the Jons Dam, which regulates the Rhône River and creates a small reservoir. This facility plays an important role in the region's water management and electricity production.
