Although interim repairs were made, heavy rains in March 2025 with storms Yana, Conrad, and Lawrence again destroyed the mote, resulting in the closure of both carriageways of the highway. Next, CHG carried out emergency repairsworking with highway maintenance services to reinforce roads with granular materials and containment bags.

To prevent new flooding, the Western Andalucía State Highway Boundary Conservation and Operation Service and the Guadalquivir Hydrographic Federation carried out cleaning, excavation, and cleaning. Removal of sludge and soil under structures and 100 meters upstream and downstream of waterways A flow of work that lasts three weeks.

The work consists of the following: Excavation and transport of sludge and sediment deposited on riverbeds, removal of material dragged by previous floods.. Work was also carried out to remove material beneath the highway structure using light machinery adapted to the reduced space to improve water flow and prevent sediment accumulation. These interventions increased the capacity of the waterway, lowered its level by 1.2 meters and increased its width to 7 meters.
