Vialidad Nacional has initiated intensive clearing operations on National Route 150 to reopen the Agua Negra Pass following a severe winter. Early efforts by the 9th District of San Juan focused on removing heavy snow, ice, and avalanches from paved sections near the Guardia Vieja National Gendarmerie post under extreme weather conditions.

As operations progressed, specialized teams and contractors reached kilometer 358, approximately three kilometers from the tunnel entrance. The work involves using heavy machinery, such as motor graders and bulldozers, to clear large snow blocks. The current strategy aims to consolidate cleaning near the tunnel before extending work to higher altitudes along the international border.
