Bridge, Rosslea, Aghnashammer and Mullaghconnelly, Co Fermanagh

This is a small-scale bridge spanning the River Finn, located near Rosslea, Aghnashammer, and Mullaghconnelly in County Fermanagh. It carries a two-lane road, alongside footpaths, over the river. The bridge is thought to have been constructed between 1840 and 1859, replacing an earlier footbridge that existed as early as 1834.

The bridge consists of two semicircular spans. The upstream (northeast) face and downstream parapet have been recently rebuilt using sandstone. The voussoirs—the wedge-shaped stones forming the arches—are of dressed sandstone, with a plain keystone on the downstream side and a rusticated keystone on the upstream side. The abutments (supporting structures at each end), piers (intermediate supports), and cutwaters (projecting elements at the river corners) are also built of dressed sandstone blocks. The cutwaters extend to the arch spring level and feature a projecting string course and a domed top. The spandrels (the areas between the arches) and parapets are of random rubble construction, topped with coped sandstone blocks, some of which are rusticated. The interior faces of the arches have been treated with gunite. The bridge deck has a slight upward curve.

An ornamental semicircular arch, constructed of dressed sandstone, is located at the east end of the downstream approach wall, likely to have formerly accommodated a mill race; a corresponding feature is absent on the opposite side. The bridge is of industrial archaeological interest.
