Arvida aluminium Bridge, Aluminum road bridge in Jonquière, Canada.

The Arvida Bridge is a deck arch bridge over the Saguenay River in Saguenay, Quebec, opened in 1950 with a span of 153.62 m and a height of 32.91 m. Its arch and roadway framing are built entirely of aluminum, the first bridge in the world made wholly of the metal.

Construction started in August 1949 and finished in July 1950, making it the world's first bridge built completely from aluminum. This achievement opened new possibilities for metal bridge design and engineering.

The bridge is named after Arvida, the planned aluminium town founded by Arthur Vining Davis, whose name it contracts. It was cited as a heritage immovable by the City of Saguenay in 2005, a status that recognises the structure itself rather than its setting.

The bridge carries road traffic between the Arvida and Ville Racine sectors of Saguenay. It was closed for refurbishment announced by the Quebec government in 2013 and reopened to traffic on 29 August 2014. Pedestrians cross on the bridge's sidewalks.

The bridge's 153.62 m span and 32.91 m height were achieved with an all-aluminium structure, a first for bridge building when it opened in 1950. It was cited as a heritage immovable by the City of Saguenay in 2005, and after refurbishment announced in 2013 it reopened to traffic on 29 August 2014.
