State road 258

Machine-translated from the Italian article

State road 258 Marecchia (SS 258) is an Italian state road that exploits the natural corridor of the Marecchia Valley to connect Sansepolcro (province of Arezzo) with Rimini. From 2001 to 2021, this road was classified as provincial road 258 R Marecchia (SP 258) in Emilia-Romagna and regional road 258 Marecchia (SRT 258) in Tuscany. It only partly follows, without retracing it, the ancient route that led from Etruria and the Upper Tiber Valley to the eastern edge of the Po Plain and to the important Roman port of Ariminum (Rimini) on the Adriatic Sea.
