This project addresses the current state of the road leading up to Amasa, which is currently narrow and offers little space for pedestrians. This makes both vehicle circulation and safe pedestrian movement challenging. Through these works, a safe, continuous, and illuminated pedestrian sidewalk will be constructed parallel to the road ascending to Amasa, extending to the Iberdrola substation, and the roadway itself will also be widened.

The base tender budget is 1,079,168.51 euros (including VAT), with an estimated execution period of 10 months. Funding will be shared by both institutions: the Amasa-Villabona City Council will cover 60.74% of the cost (655,486.95 euros), while the Gipuzkoa Provincial Council will contribute the remaining 39.26% (423,681.56 euros). The Department of Road Infrastructures and Territorial Strategy will be responsible for executing the works, and upon completion, the road will become municipal property.

Furthermore, the intervention will facilitate the installation of new telecommunications conduits and the improvement of the natural gas distribution network. It is anticipated that the works will be tendered this year and carried out in 2027. Additionally, at the same N-I junction, the Provincial Council is undertaking a complementary action at the beginning of the road towards Amasa (GI-3751), constructing a 2-meter-wide pedestrian sidewalk. This work is already advanced and is expected to be completed by the end of May.
