The work is strategic in nature because it is located on a key road such as Via Casilina and the intersection with Via Siculiana. The aim of the project is to improve traffic flow at a high-traffic intersection, prevent accidents, reduce travel times between neighbourhoods, and increase connections between the neighbourhoods along Via Casilina and the C metro line. The project involves the construction of a roundabout on Via Casilina at the intersection with Via Siculiana, an important road connecting the neighbourhood. In addition, a new road about 140 metres long will be built, complete with a rainwater drainage system and new lighting, to provide access from the Via Casilina/Via Siculiana roundabout to Via Carlo Fornara, with the aim of diverting traffic towards the Borghesiana/Vermicino neighbourhood. The aim of the project is to improve the connection between Via Casilina and Via Siculiana, i.e. the road leading into the neighbourhood between the Borghesiana and Fontana Candita/Due Leoni metro stations, as well as to strengthen the connection with the Borghesiana/ Vermicino neighbourhood through a new road linking to Via Casilina. The change to the procedural schedule is justified by the complexity of the design, which required more time and money due to the particular morphology of the territory, and by the need for expropriation procedures and fundamental urban planning changes in order to start the work. The intervention is divided into two functional sections and includes:

• Section ID 159.f a: Section 1: roundabout intersection between Via Casilina and Via Siculiana for the construction of the north side of the road network, financed under Prime Ministerial Decree 11/06/2024, for an amount of € 1,000,000.00.
• Section ID 159.f b: Section 2: roundabout intersection between Via Casilina and Via Siculiana for the construction of the south side of the road network and connection to Via Carlo Fornara, financed with funds from Roma Capitale's Budget, for an amount of € 1,570,000.00.
