There are few places in Kilkenny where the city's medieval past and modern engineering can be seen so clearly together as John’s Bridge. The crossing links John Street with the city centre and has served as an important route across the River Nore for centuries. A bridge was in place here shortly after 1200, connecting the developing town with the walled city and helping people, goods and trade move between the two sides of the river.
The present bridge has a much more recent story. During the great flood of 1763, Green’s Bridge was swept away and a large crowd gathered on John’s Bridge to watch the destruction carried downstream. When a floating cabin came into view, many of those watching moved towards the riverbank, but around sixteen people remained on the bridge. The structure suddenly collapsed, and all sixteen lost their lives. It was one of the most tragic events in Kilkenny’s history, and the story of that flood remains closely associated with the bridge.
The John’s Bridge you see today was completed in 1910 and was an important example of early reinforced-concrete construction. It used the Hennebique ferro-concrete system, with the bridge designed for the local authorities by Kilkenny County Surveyor A.M. Burden and the engineering designs signed by Louis Gustave Mouchel of London. Its single sweeping arch spans the Nore and was, at the time of completion, the longest single-span reinforced-concrete bridge in Ireland or England. When you're crossing it, it's worth taking a moment to look at the curve of the arch and the River Nore below.
John’s Bridge is one of the places I enjoy talking about on my walks because you can stand in the same spot and connect several different periods of Kilkenny’s history. If you'd like to hear the stories behind the streets and landmarks as you explore the city, come along and walk Kilkenny with me on one of my daily walking tours.
