This past year the American Pilgrims on the Camino gave a grant of $6,000 to the Associacion de Amigos del Camino en Cádiz to provide for way markings on the Camino Via Augusta from Cádiz to Sevilla. The Via Augusta is 173 km and takes roughly 6 days to walk. In Sevilla it connects to the Via de la Plata which then goes from Sevilla to Astorga where it connects with the Camino Frances.
Here is a link to the Confraternity of Saint James which describes the Via Augusta.
