From Arrochar on Loch Long, the A83 rises steeply up Glen Croe towards the vantage point known as Rest and Be Thankful.  Just beyond the crest, it skirts Loch Restil and then drops at a gentler pace down towards Glen Kinglas.

The bridge was built by General Caulfield in 1745, and it originally carried a military road into the heart of the Highlands;  the whole road-making programme was designed by the English government to subdue the recalcitrant Scots after the first Jacobite uprising.
