The Bauladu variant is part of the larger project to speed up the San Gavino – Sassari – Olbia line, and involves the municipalities of Solarussa, Bauladu and Paulilatino, covering approximately 8.5 km. The aims of the project are to improve the performance of the railway link by reducing the development of the section between Solarussa and Paulilatino (currently 19.5 km); eliminating sections with a maximum gradient of 25‰ and; eliminating 4 PL. The variant project does not include the restoration of the Bauladu Milis stop. The open-air sections cross areas with archaeological findings that are subject to both direct and indirect constraints.
