The Ripalta-Lesina railway track-doubling project stretches 7,983 metres in the province of Foggia, affecting the municipalities of Serracapriola and Lesina. The latter represents a critical point for the Adriatic Route, influencing the management of railway traffic and limiting the fluidity of circulation due to crossroads and priorities. The works begin at km 464+268 of the existing line and end at km 472+371, providing for the widening of the railway seat on the upstream side, the construction of a double-track variant and the expansion of the line on the sea side between km 5+200 and km 7+470. The main work is the Ripalta viaduct, 1,175 metres long, between km 2+565 and km 3+740. The project also includes the decommissioning of the Ripalta electrical substation, currently out of service, and the construction of a new medium-voltage ESS near the station, improving the efficiency of the infrastructure. To ensure adequate drainage and prevent hydraulic interference, several mitigation works are planned.
On the Fosso Olivella, a three-pipe canalization system will be built with upstream and downstream regulation works. Fosso Paradiso will be reprofiled in the section crossed by the Ripalta viaduct, while the Capoposta Canal will see the replacement of the existing structure with a new hydraulic work and the adaptation of the riverbed. Finally, the Fosso Pontonicchio will be equipped with a new outflow system to optimise water management. These solutions will improve the hydraulic safety and stability of the area, making the infrastructure more resilient to extreme weather conditions.
