My father, Royston Foot, who has died aged 95, was a civil engineer with an expertise in precast concrete who worked in motorway construction and on newspaper buildings. He was a key part of the design team for Spaghetti Junction in Birmingham, which recently celebrated its 50th anniversary.
Initially, he was irritated by the name and always called it Gravelly Hill Interchange, but over time, he grew to accept and then to delight in it. He was interviewed several times for the BBC and featured in a series, The Secret Life of the Motorway, telling stories about its construction and design.
