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.
I have heard the same thing about semiconductor factories in Taiwan. Don't know if it's true or urban legend.
Wouldn't surprise me - their chip foundries are the most robust defense they have. If they were gone, Taiwan would be "just another Island that will cause you loads of headache internationally and because of a nearly guaranteed resistance - and you expended a lot of resources for it on top"
They’re 100% going scorched earth if China manages to make landfall
They’ll literally put the world to a post-apocalyptic state, we can’t get new chips for any electronics in quantity for a good half decade or more.
I wouldn't say post-apocalyptic. Yes, we won't have access to performant new chips anymore, but most critical infrastructure doesn't need performant new chips. It would be a rough period, for sure, but not apocalyptic
And if worst came to worst, the military/government could requisition consumer equipment, or less critical business equipment
