He has many years of experience in similar projects. César López was one of the fore-men of the Navia Viaduct project, also built by FCC in Asturias. He is currently in charge of the construction of the Las Dueñas-Muros de Nalón section of the Cantábrico Highway.

The new 8.7 km-long section will contribu-te to reducing traffc congestion of this road currently in use. The most salient aspect of this route is that 37% stretches over singular structures and 27% is above ground in the Concha de Artedo Viaduct.

Once the 1,118m-long viaduct is comple-ted, it will be the longest one in Asturias and the highest one upon piles, some of which are over 100 meters high.

Diffculties encountered during exe-cution

Cesar mentioned that the strong wind in this region had an impact on the execution of the foundations as well as the assembly of the piles. The up to 90 mm/h winds made necessary to suspend work on several oc-casions. This has been particularly diffcult, he told us.

This is why it was necessary to stress the ex-perience and professionalism of the emplo-yees who were involved in assembling the piles, and to this purpose, special training was also provided. Complying with safety measures during the execution of the project

No accidents during project execution
