Tromie Bridge carries the B970 across the River Tromie a couple of miles or so east of Kingussie. It is the only public road bridge across the river, but while it is a listed structure, very little seems to be known about it.
A cursory glance tells us that it is a single-span stone arch bridge, with a slight rise from west to east. There is also a substantial retaining wall on the west bank carrying the road out across the steep river bank. As for age, while this is clearly a historic bridging site and this an old bridge, it is perhaps not as old as it might appear. The majority of the facing stone is pretty rough rubble, but the lowest courses and the inside of the arch seem a lot more regular. This suggests machine cut stone from a distant quarry, brought in by train, with local stone used for the less important upper structure. The second half of the 19th Century therefore seems plausible, but by no means certain.
