Alvie Bridge crosses the small Allt Dibheach as it leaves Loch Alvie a couple of miles or so south west of Aviemore. The bridge was built to the design of Owen Williams and is a near copy of Crubenmore Bridge further south on the former A9. Alvie Bridge itself now carries the B9152, since the new A9 route was built through Strathspey.
The bridge is constructed of Concrete and has two arches across the small stream. The abutments and central pier stick out significantly from the deck, like the legs of some crouching insect ready to pounce. This gives the bridge a very unusual appearance when viewed from the riverbanks, however from the road the only sign of anything strange is the triangular refuge over the central pier.
