France, 2011 - 2013
Located south of Lyon on the Rhône, slightly upstream of the confluence with the Saône river, the new Raymond Barre Bridge is in an exceptional location, between the right bank peninsula undergoing urbanisation and the left bank riverside park adjoining the Gerland district and the famous Halle Tony Garnier.
This structure, between the future museum of the confluences under construction and the Sanofi head office, intended for the T1 tram and eco-traffic has a main span of 150m built at an angle to the axis of the river reminiscent of the steel railway bridge of Mulatière sur la Saône.
Seen from the banks and the A7 motorway, this bridge with radiating arches will be the new "porte de Lyon" (gateway into Lyon) over the Rhône river.
- Length of the structure: 264m
- 3 spans: 50.8m - 171.8m - 36.9m.
- Span between bearing surfaces: 72.3m - 152.2m - 38.2m.
- Steel bridge deck, orthotropic slab
- 2 spans assembled on an area near the work site and transferred to the site using towed barges on the Rhône.
- P1 pier in the middle of the Rhône built in a 15m-deep cofferdam with a surface area of 350m².
