Appraisal

This fine late nineteenth-century bridge survives in good condition, and is an integral element of the engineering heritage of County Donegal. Its construction using steel girders forming the deck resting on robust rock-faced masonry piers is of technical merit and it represents one of the few examples of a bridge of this type in Donegal. Its form and construction (steel deck and rock-faced masonry construction to the piers and abutments) is reminiscent of a number of railway bridges built throughout Ireland during the late-nineteenth century. The stringcourse to the abutments and piers adds an subdued element of decoration to and otherwise robust and functional structure. It was built by W.J. Glen, Engineer. This bridge is a landmark structure in Donegal Town, and remains an important transport feature in Donegal Town, linking Diamond with Tyrconnell Road to the north. It may have replaced an earlier bridge to the same site.
