This path is possibly suitable as an (temp) addition to the Ciclovia Adriatica route. It extends to the Ferrovia Adriatico. From there a few hundred meters back to via Roma then cross the river Tronto via the SS16. There is a cycle/pedestrian bridge in the planning from Martinsicuro to Porto d'Ascoli, but that will be the end of the decade, optimistically. Maybe a cycle aficionado or a trekker locally can inspect this.
