The operation consists of the construction of a path between Kilometric points 29+ 225 and 30+ 920 of the regional road PO-551 externally limited by a concrete curb that differentiates it from the rest of the platform and, in cases where the available space is sufficient, a plant strip will also be available between the path and the road to improve safety and its integration. The path is designed throughout its length with a minimum width of 1.5 meters. Given the characteristics of the orography in the field of action, the execution of structures in several sections is planned. Specifically, it will be necessary to execute more than 300 m of the path by extending the road platform with a cantilevered structure, as well as extending the height of the retaining walls or executing new walls.
