This work focuses on the determination of protective measures for rockfall in a unique area of a mountain road in the Tramuntana range of Mallorca with a daily traffic estimated at 7.200 vehicles. The wildfire that affected the area in the summer of 2013 has increased the risk of the road further accelerating the need to protect this area already sensitive. The local authorities have decreed some emergency measures and studies to protect the road from this kind of events. The first studies performed have shown a more risky scenario after the fire because of the lack of vegetation cover and this situation has involved the construction of some new protection structures on the rock slopes to decrease the rockfall risk. The performance of the studies has been undertaken by means of analysis of trajectories on simulated rockfalls to design protective measures. New protection structures have been installed during 2015.
