The Pont Mirabeau crosses the River Seine in the west of the city of Paris. It links the rue de la Convention and Place Mirabeau with the rue de Rémusat.
The central span (volée) is 93 metres (306 ft), and the side spans (culasses) 32.4 m (106.5 ft). Width 65 ft 8" between parapets. When completed, it was the longest and highest bridge in Paris.

The 1896 drawing shows the principle and some structural details. It is a cantilever bridge. Each half, assembled from seven steel frames, is pivoted on the river piers. The balance is such as to exert pressure on the central hinge and to produce a shoreward reaction at the pier hinges, while the outboard ends are anchored to the abutments by links having two pinned joints.
2744 tons of metalwork were incorporated, of which 2077 tons were rolled steel from the Aciéries de Longwy, 82 tons forged steel, 385 tons of rolled wrought iron from Denain et Anzin, and approx 200 tons of ornaments. Masonry by Messrs. Letellier.
