Freyssinet

The Brotonne bridge, built in 1977, marked a decisive stage in the construction of cable-stayed bridges with prestressed concrete aprons.
The structure is 1,278.4 metres long and comprises a cable-stayed bridge with three spans, respectively 143.5 metres, 320 metres and 143;5 metres long. The apron is 3.8 metres high throughout its length and includes two throughways 6.5 metres wide, a central separation 3.2 metres wide, and two sidewalks 1.5 metres wide.
