"The Ha'penny Bridge, Dublin" (Dublin City Council / Four Courts Press, 272pp, 2016) [amazon.co.uk] documents only one of Dublin's bridges, although certainly the best known.
Built in 1816, the Ha'penny Bridge (named for its toll) was the first iron bridge in Ireland. It was designed and fabricated by the Coalbrookdale foundry in Shropshire, the same as had built the pioneering Iron Bridge in 1779. The new crossing replaced an existing ferry, and was promoted by the ferry proprietors William Walsh and John Claudius Beresford as a private initiative.
The bridge has survived two centuries of often eventful Irish history, and this book wisely takes a very open-ended approach to documenting its subject.

Different authors contribute different chapters to the book. The text drives onto, across, beneath and away from the bridge; treating it as a vantage point to explore the bridge, its surroundings, and its context from many angles.
David de Haan offers a history of Coalbrookdale, source of Englands' best known iron bridge, and of the cast iron shipped to Dublin. This explains everything from the iron smelting process to the broader industrial transformation which allowed iron to challenge stone for economy. Gerard Smyth recounts the main points of the bridge's history, while Logan Sisley describes the the fortunately ill-fated 1913 plan to replace the bridge with the Hugh Lane Gallery.


The penultimate chapter, by architect Seán Harrington, describes his design of Dublin's Millennium Bridge, now one of the main places from which to view the Ha'penny Bridge, and a structure where the various differences and similarities are constructive. The final chapter consists of Michael English's photographs of the bridge taken at different times of day and different periods in the year. These are excellent, well portraying way in which such a simple structure can appear so very different as hours and seasons pass.
Although the book is extensive in its coverage, one area where it is lacking is in any discussion of the Ha'penny Bridge's siblings. The distinctive form of its cast iron ribs, with two layers of quadrilateral braced ribs (like the more modern Vierendeel girder), was not new in 1816, indeed the appearance of the bridge was essentially a copy of Thomas Telford and Thomas Stanton's Meole Brace bridge, completed in Shropshire in 1811 and supplied by William Hazledine. The same or very similar design was used again in 1813 for the Cantlop Bridge, and then repeated after completion of the Ha'penny Bridge, in 1818 for the Cound Bridge (now reconstructed in Telford) and in 1823 at Stokesay. If you look at close-up images of Cantlop Bridge, the relationship is very clear.
Overall, however, this is an excellent book, highly relevant to anyone with an interest in Dublin or in bridges, particularly the role that they play in urban history. As already noted, it's a very attractive book, exceptionally well-illustrated, and a great example of what can be produced by people who allow their passion for a subject to drive what they do.

Indeed a gem of a book.
It was published in the year of its 200th anniversary and I did a blog post on the launch.

Earlier in the year there was an event at the bridge itself attended by descendants off Beresford and of the engineer at the Shropshire works.

Following that there was a presetation of much of what was subsequently included in the book.
