Hidden military bridge now listed building.

And the latest instalment of 'you learn something new every day'.
"A 'hidden' canal bridge, hailed as a 'masterpiece of military engineering' that played a crucial role in both World Wars, has been awarded Listed status. The Inglis Pyramid Bridge, which spans the Basingstoke Canal in Aldershot, Hampshire, has now been listed at Grade II due to its unique military history.
The structure is one of the few remaining military structures in England dating back to the First World War, designed by War Office engineer Charles Inglis. Before his commission into the Royal Engineers and appointment to the War Office, where he oversaw bridge design and supply, Inglis lectured in Engineering at the University of Cambridge.
Constructed from lightweight steel, the bridge was quick and easy to assemble with minimal training and could be reused. Its design was effectively utilised by soldiers during the First World War, particularly in France, and significantly influenced the development of future military bridges.
The 'hidden in plain sight' bridge near Aldershot is one of only ten Inglis Pyramid Bridges known to have been manufactured during the 19141918 conflict and is likely the only example still serving as a bridge in England. Inglis bridges were deployed by the British Army and Allied Forces as far away as Pakistan and India."
