PIARC Prize "Road Safety" - Road Management System for Adverse Weather Conditions: Fog and Wind

Illustrations © Authors

The section of the A-8 Cantabrian motorway (hereinafter A-8) near Alto del Fiouco, between km 545+500 and 549+500, is prone to specific weather conditions involving periods of dense fog combined with strong winds. These make driving difficult and sometimes lead to the section’s closure with vehicles diverted to the N-634 as the minimum safety conditions for operation cannot be guaranteed.
