Unusual Bridge Across the Basingstoke Canal Listed
An unassuming metal bridge which crosses the Basingstoke Canal near Aldershot in Hampshire is now listed at Grade II thanks to its unusual military history.
The structure’s listed status has been awarded by the Department for Culture, Media and Sport on the advice of Historic England.
Known as the Inglis Pyramid Bridge, it is a rare example of an Inglis Portable Military Bridge (Light Type). It is one of the relatively few military structures in England that date from the First World War.
Rare First World War Bridge
This was the first portable bridge designed by War Office engineer Charles Inglis (pronounced Ingalls). Made of lightweight steel, it was quick and easy to construct with little training and could be reused. Soldiers used the design effectively during the First World War, especially in France, and it was hugely influential in developing future military bridges.
The bridge near Aldershot is 1 of only 10 Inglis Pyramid Bridges known to have been manufactured during the 1914 to 1918 conflict and is likely to be the only example still in use as a bridge in England.
Inglis bridges were used by the British Army and Allied Forces as far afield as Pakistan and India. The patented design continued to be refined, and Inglis bridges were still used during the Second World War before being largely replaced by the stronger Bailey bridge, pioneered by Donald Bailey.
Later versions of Inglis bridges can be found in Monmouth, Wales; on display at the Royal Engineers Museum in Gillingham, Kent; and near Hunterville in the Rangitikei district of the North Island of New Zealand.
The Aldershot Inglis Pyramid Bridge is owned by the Ministry of Defence and carries services across the Basingstoke Canal.
The Inglis Pyramid Bridge over the Basingstoke Canal has an extraordinary backstory. Hidden in plain sight, this deceivingly simple structure is a masterpiece of military engineering and was the first version of a type of lightweight bridge which was deployed extensively overseas. The bridge is thought to have been brought back to Aldershot from France and remarkably has been in its current position for at least 60 years.
Sir Charles Edward Inglis (1875 to 1952)
Inglis was a lecturer in Engineering at the University of Cambridge before being commissioned into the Royal Engineers and appointed to the War Office, where he was in charge of bridge design and supply.
After the war, Inglis was awarded an OBE and returned to Cambridge as a Professor and Head of the Engineering Department, a post he held until his retirement in 1943. He was president of the Institution of Civil Engineers from 1941 to 1942. In 1945, he was granted a knighthood for his public services.
Inglis was held in high regard; one of the buildings at the Engineering Department of the University of Cambridge is named after him.
