3. Pre-stressed concrete cantilever bridges
The very frequent use of the corbelled construction method testifies to the many advantages of this method, which eliminates the need for bending or scaffolding. In the most common cases, this involves building a bridge deck in sections from the piers: once a section, called a "voussoir", has been built, it is attached to the section already built, using prestressing. The section then becomes self-supporting, enabling the resources needed to build the next section to be deployed. Once all the sections have been completed, the result is what is known as a flail (figure 5 ).

Standards and norms
Bridge design and dimensioning are governed by French standards transposing European standards (Eurocodes), and may be supplemented by national standards. In seismic zones, the requirements of current national regulations must be taken into account.
