There are contingency plans in place for all senior members of the royal family — to be used in case of their death — each of which is given a different, typically bridge-based code name. When Prince Philip died in 2021, his funeral plans were kicked off by the code name "Operation Forth Bridge" — named after a railway bridge near Edinburgh, Scotland.

"Operation Menai Bridge," named after a bridge in Wales, is a code name that will be used in the case of King Charles III’s death. One can actually see the code name being used in Season 4, episode 9 of “The Crown,” which featured a real-life event that Charles experienced in 1988, where he was briefly presumed dead following an avalanche.

"Operation Tay Bridge" was the code name used when Queen Elizabeth II’s mother passed away. However, the Queen Mother's husband, King George VI, who reigned during World War II, broke the bridge trend, instead receiving the code name "Operation Hyde Park Corner," the name of a tube (subway) station at the corner of Hyde Park in London.

The funeral plans for the late Queen Elizabeth II were listed under the code name "Operation London Bridge" — which had been under construction since the 1960s. The choice of London's self-named monument, London Bridge, may signify precisely how important some regard the queen to be to the heart of the nation.

It seems like only senior royals get funereal code names, bridge-based or otherwise. However, the other members do have around-the-town nicknames like Danny Collins and Daphne Clarke, for the Duke and Duchess of Cambridge, respectively, and David Stevens and Davina Scott, for the Duke and Duchess of Sussex — before they departed from the royal family.
