Inglis Bridge, Monmouth
The Grade II listed bridge crosses the River Monnow in the Monmouth suburb of Osbaston.
It is an Inglis Bridge, constructed in 1931, and is the only known example in Britain of an Inglis bridge still in public use.
The Inglis bridge was conceived and developed by Charles Edward Inglis. The Warren truss girders are assembled from tubular steel sections joined by cast steel nodes, and have a 90 ft span with a 9 ft 6 in wide deck. The cross members are rolled steel joists, lightened by holes cut in the webs.
Few Inglis bridges have survived. One crosses the Basingstoke Canal at Aldershot, but it is not in public use. A 50 ft span example, formerly at RAF Sandtoft, was removed and partly reassembled in South Yorkshire, with a smaller section going to the Royal Engineers Museum at Gillingham, Kent <ref>[1] Doncaster Free Press, 9th January 2018: Historic military bridge makes final journey</ref. A replica Inglis Bridge has been erected in a park in Leyland, Lancashire in 2016. Other Inglis bridges survive in Canada, Germany, Pakistan, and on the Simpson Reserve in New Zealand.
