Inglis Bridge

Sir Charles Inglis (31 July 1875 – 19 April 1952) was a British civil engineer. While a lecturer in mechanical engineering at King's College, Cambridge, Inglis joined the Cambridge University Officers' Training Corps and on the outbreak of World War 1 was commissioned into the Royal Engineers. Appointed director of the bridging department, he designed a transportable steel bridge that could be erected in a day. Named the Inglis bridge in his honour, the design remained in use by the British Army throughout the First World War and the inter-war period, until being superseded by the higher capacity Bailey bridge in 1940–1941. The Inglis Bridge at Monmouth was built by the Royal Monmouthshire…

The bridge is constructed of tubular steel and comprises a 27.4 m single span with a 2.9 m deck. It is supported by longitudinal stringers and two spans of lateral bracing. The design is of the Warren truss type. The Inglis bridges were constructed using prefabricated components, allowing for rapid deployment and reuse in combat conditions. The Mark I design comprised steel tubes of differing lengths, which led to errors during assembly. The Mark II model standardised the steel tubes used to a single length. Inglis Bridge is a Grade II listed structure.
