Most bridges here do, and often when one needs to be demolished and rebuilt, the military blows it up just for practice.
Edit: Source for the sceptics
The deep demolition, which became a central element in Finnish post-war demolition tactics, and especially the development of readiness to counter surprise attacks that emerged as a threat scenario in the 1960s, received significant support immediately after the wars. The decision concerning structural demolition preparations for bridges was made on January 15, 1946. These preparations meant building charge wells, charge chambers, charge pipes, and charge hooks. Authorities responsible for constructing bridges were required to include the aforementioned structures in their plans, which significantly improved the readiness to destroy the bridges.
If it was not possible to place the charge space inside the abutment or pier, charge hooks could be embedded in the supports during the casting phase, to which the charges could then be attached.
There were also plans to bury nuclear landmines stuffed with chickens across Germany.
Britain: Some of you will be reduced to nuclear ash, but that is a sacrifice I am willing to make.
Today I learned something new, and it was completely insane. Thank you.
While reading that I thought they intended to make mounds akin to the ones made by megapodes (sort of chicken-like), but now I understand why people have mistaken a declassified data for an April Fools
I never expected to read the term “chicken powered nuclear bomb” in a serious Wikipedia article. Yet here we go!
BTW, I think we have left the mildly interesting context by now… :-)
