Cantilever bridges

The cantilever bridge is built from multiple segments that can either be precast, or cast-in-situ.
From 1962 to date, 70% of prefabricated segment bridges built worldwide required Freyssinet's technology and expertise. Their advantages are:

If the segments are cast-in-situ, concreting is undertaken by means of steel carriage form travelers supporting the formworks and proceeding symmetrically on each side of the supports. As the segments are cast and loaded at different times, it is important to accurately determine the deformations. However, the advantages consist of:


The span length is usually up to 150 meters.
