Old Bridge, Allt Anndeir, Dalnamein Lodge

The Old Bridge at Allt Anndeir, near Dalnamein Lodge, is an early 18th century single arched military bridge spanning the Allt Anndeir. It is now used privately and sits immediately north of the A9 road, to the northeast of Dalnamein Lodge. The bridge is constructed of rubble with roughly worked voussoirs forming the arch. The carriageway is now grass-covered and has low parapets on both sides. The bridge is founded on bedrock on either side of the river. A notable feature is a joint visible on the underside of the bridge, indicative of a historical widening to the east of the original structure. The bridge has gently battered buttresses on each side, and the carriageway is splayed at both ends. A carved stone milestone is located immediately northeast of the bridge.

The bridge is part of the road network built in Scotland between the early 1720s and the late 1750s, with approximately 400km constructed under General Wade and 1300km under Major Caulfeild. This particular bridge likely dates to between 1725 and 1740 and relates to the Blair Atholl to Dalwhinnie section of road. It was altered with a widening and the addition of parapets. The bridge ceased regular traffic use after upgrades to the A9 and the construction of a replacement bridge to the south in the late 1920s.
