Machine-translated from the Italian article

State road 658 Potenza-Melfi (SS 658) is an Italian state road whose route runs entirely within Basilicata. It connects state road 407 Basentana to state road 655 Bradanica at Melfi. The route, entirely within the province of Potenza, consists largely of a carriageway with one lane per direction of travel, except for some steeper stretches, for which a third lane for heavy vehicles has been planned.
