The Pont Lafayette is a road bridge in Lyon over the Rhône . It connects the Place des Cordeliers in the 2nd arrondissement on the peninsula formed by the Saône and Rhône with the Cours Lafayette in the 3rd arrondissement on the left bank.
The next bridge upstream is the Passerelle du Collège, downstream the Pont Wilson .
description
The 218 m long and 20 m wide bridge has four lanes, two of which are bus lanes and two lanes for general traffic from the right to the left bank, and two 4.7 m wide sidewalks and cycle paths.
Since the level of the adjacent streets had to be maintained, but the authorities only allowed three arches, a very flat construction had to be chosen. The bridge therefore consists of three very flat segment arches with spans of 63 + 67 + 63 m and an arrow height of 1: 15.91. About a third of the western arch on the right in the direction of the river disappears under a later widening of the promenade. The left arch spans the quay with the banks and a cycle path. Each segment arch consists of eight steel ribs with a rectangular hollow box cross- section, which are supported on transom joints on the abutments and on the approximately 3 m wide masonry pillars, are reinforced with cross and diagonal braces and on which the only 0.40 m high deck slab stands is.
On the foundation plates of the pillars are large statues made of white limestone depicting allegories of the Rhône and the Saône. These are copies of the originals on the Louis XIV monument on Place Bellecour. On the abutments there are coats of arms of the city of Lyon with the year 1888–1890 .
The bridge, built between 1888 and 1890, was designed by the engineers Tavernier, Girardon and Fabrègues. The steel structure of the bridge was designed by Schneider & Cie. manufactured and assembled in Le Creusot . The Pont Lafayette was thus one of the first, if not the first, road bridge with flat segment arches, the supporting structure of which was made entirely of steel and no longer, as was customary until then, made of wrought iron .
history
The first bridge at this point was a bridge built between 1825 and 1828 made of nine wooden arches on brick pillars. It was the third oldest Rhône bridge in Lyon. It was initially to be called Pont du Concert after a music hall on Place Cordeliers, but was renamed Pont Charles X in 1824 after King Charles X , who had approved its construction. In 1831 it was transferred to Pont Lafayette by order of Louis-Philippe , after General Lafayette , who had taken command of the National Guard in 1830 and enabled Louis Philippe to ascend to the throne. At the beginning of the 1880s the bridge showed signs of old age, so that a new construction was decided and commissioned in 1887.
