Trinafour Bridge

Trinafour Bridge is an early 18th century single arched military bridge spanning the Errochty Water. Now open to pedestrians and cyclists, it is situated west of the B847 road within the small settlement of Trinafour. The bridge is constructed of stone, with roughly worked voussoirs forming a slightly pointed arch. The carriageway is now grass covered and retains low parapets on either side. A joint runs along the underside of the bridge, indicating a historical widening of the structure. A rubble masonry buttress is present on the east side, and the ends of the carriageway are splayed, with granite boulders serving as finials on the parapets.

The bridge’s construction relates to the Aberfeldy to Dalnacardoch section of military road, built as part of a wider network constructed between the early 1720s and the late 1750s under the direction of General Wade and Major Caulfeild. These programmes aimed to improve communications between garrisons and expand the road network across Scotland. The bridge was likely built between 1725 and 1740. It appears to have been altered with a western widening and the addition of parapets. The bridge ceased to be used as a road bridge when the more modern bridge on the B847 was built to the east of Trinafour.
