The proposed work (Pontino Rome – Latina Integrated Intermodal System) falls within the context of a new design for a north-south motorway corridor, necessary to decongest the Apennine stretch and to create cross connections between the Tyrrhenian coast and the Adriatic one.
The C.I.R.L. highway covers about 20 km, with cross-section of 2 lanes in each direction of 3.75 m and 2 emergency lanes of 3.00 m.
The C.I.R.L. is characterized by the following main structures : 22 bridges for a total of about 4620 m, with a deck consisting of four beams, spans 35 m long, four tunnels for a development of 300 m, 8 flyovers, 5 underpasses.
The 'Cisterna-Valmontone' route is characterized by the following main structures: 8 viaducts, for a total of about 3280 m, with a deck consisting of four beams, spans from 35 m to 20 m long, 2 flyovers, 8underpasses.
ContinueTotal length 20 km; 22 viaducts (total length 4620 meters); 4 artificial tunnels (total length 300 meters); 8 overpasses; 5 underpasses.
Total length 11 km; 8 viaducts (total length 3280 meters); 2 overpasses; 8 underpasses.
Alongside the highway through almost all of the development project run complanar roads (2 lanes in each direction of 3.50 m). It is also provided the creation of a new junction at Castel Romano and a section to bypass the town of Pomezia.
The route 'Cisterna-Valmontone' connects the Rome-Latina project to the A1 motorway and runs for about 11 km, with cross-section of two lanes in each direction of 3.75 m and platforms of 1.75 m. The crossing of the A1 motorway will be solved with a cloverleaf junction in a split-level.
