Motorcycle travel · Spain

Hello, Next October we’re planning to ride the Ruta de la Plata by motorcycle—a historic Spanish route that runs from Gijón to Seville, also known as the N630. Has anyone here already ridden it? Unfortunately, I’m worried that parts of the N630 may have disappeared or merged with the A66 motorway, forcing us to ride long stretches of highway, which we’d rather avoid. Thanks in advance for any tips or details about this route!
