Best Roman Road?

I took the traditional route, rather than a scenic detour and am in a town called El Burgo Ranero. Not a bad place, in fact a good place to have watched Real Madrid vs Juventus last night. 

What I didn't realize was that I'm now out of position to walk 17km on the best preserved Roman road in Spain, the Calzada Romana (not sure if that's the official name). I think I have a way to get there where I'm at least on it for 10 km or so. 

I'll let you know!
