A motorist called 911 after discovering damage to the crash barriers on the bridge in the municipality of Cerdedo-Cotobade. Shortly thereafter, the emergency services received an emergency call from the bus, which facilitated the search for the wrecked vehicle. The rescue work had to be interrupted overnight due to bad weather. The search resumed on Sunday morning with the support of mountain rescuers and a helicopter.
