The Passerelle Eiffel or Pont ferroviaire Saint-Jean is a railway bridge opened in 1860 and now disused over the Garonne in Bordeaux .

The rail traffic runs since 2008 over the immediately neighboring Pont ferroviaire Garonne . The left abutment and the part of the old bridge extending over the left bank had to give way. On the right bank, the bridge crosses the Quai Deschamps and ends at the right abutment, behind which the embankment has also been removed.

history

The bridge around 1900

The bridge served to connect the railway networks of the Compagnie du chemin de fer de Paris à Orléans and the Compagnie des Chemins de fer du Midi . It was now possible to travel by train from Paris via Bordeaux to Hendaye on the Spanish border and via Toulouse to Sète (then Cette ) without taking a carriage from the former Gare d'Orléans on the right bank of the river over the nearby Pont de Pierre to the Bordeaux-Saint train station - Having to switch jeans on the left.

The bridge was built to the design of Stanislas de la Laroche-Tolay and Paul Régnauld under the direction of the young Gustave Eiffel between 1858 and 1860.

description

The double-track bridge has five main openings and two secondary openings over the bank areas. Of the originally 511 m long bridge, 475 m are left. Based on the Langon railway bridge built shortly before over the Gironde, the pillar spacing was set at 62.86 + 5 × 77.06 + 62.85 m.

The structure consists of two 6.35 m high wrought iron girders with parallel belts at a distance of 8.60 m. At that time they were referred to as lattice girders , but the high Andrew's crosses framed by posts are similar to a half-timbered structure. The bridge has an upper cross brace.

The pillars consist of two cast iron pipes with a diameter of 3.60 m, which are filled with concrete. They served as caissons to lower the pillars to a depth of 17 m.

In 1862 the bridge was given an iron footbridge ( French passerelle ), which was dismantled in 1981 for safety reasons.

When the neighboring new bridge was built, the old bridge should have been completely demolished. At the insistence of the (French) head of UNESCO , however, it was decided to largely preserve it.

Since 2010, the bridge is a monument historique under monument protection .
