Castlecary Roman Bridge

I was back on my Mungo walk today taking more photographs. Starting at Castlecary, I was determined to get a closer look at the old Roman bridge hidden away below the M80 and the towering Castlecary Arches, that carry the main Glasgow to Edinburgh train line. 
It's a far cry from how it would have been in Mungo's day some 1500 years ago!
