Finn Bridge is a bridge built in the 1860s that lies across the River Finn (not to be confused with the River Finn in County Donegal) between County Monaghan in the Republic of Ireland (close to the village of Scotshouse) and County Fermanagh in Northern Ireland.
Finn Bridge is a border crossing between the Republic and the North. It was used by Gardaí, RUC and also the Irish and British Army during "The Troubles". The bridge was closed to vehicles by the British Army by fixing concrete pillars onto the middle of it. This was intended to prevent the IRA from moving easily between the two areas. The only way across was by walking through the gaps between the pillars. Since the Northern Ireland peace process, the bridge has been reopened to vehicular traffic.
