The bridges where Route 3 crosses the San José, Queguay and Dayman rivers are three multi-span bridges, with a lower arch of 32 m span, originally built in the 1930s in reinforced concrete.

In the new project, the deck was widened and the load-bearing capacity of the structures increased. The solution modified the longitudinal functioning, linking the deck with the keystone of the arches, and included an external prestressing, between the deck and the arches, to enhance their embedment.

It was sought that the resulting lower image rescue the original form, which is valuable and represents a heritage of the typology.

The works were carried out keeping traffic over the bridges.
