The Truggia bridge crosses the Liamone.
The length of its course is 40.9 km. The Liamone takes its source on the western slope of Monte Cimatella (2,099 meters high), in the territory of the municipality of Letia, at an altitude of 1,850 meters. In its upper course, it forms the Piscia a l'onda waterfall between the altitude of 546 meters and the altitude of 514 meters. After an impetuous course of nearly 41 kilometers, it empties into the Gulf of Sagone north of Ajaccio, between the two municipalities of Coggia and Casaglione.
The Liamone river does not flow directly into the sea, the beach of Liamone separates it from it.
The neighboring coastal rivers are to the north the Porto, to the south the Prunelli.
