At least in Finland and Sweden those highways-as-emergency-airfields are always in use, no need to prep the area or remove dividers in any way. They are mostly used by the army for practicing, basically the police will just close the road so the army can practice, and when the army is done the road is opened again.

Plus the Swedish Gripen jet fighters are designed to operate off roads rather than requiring long, smooth runways, as well as be main†ained in the field.

Switzerland hides some of their jets in mountains and uses the highways as runways.

Swiss military is a really interesting topic from so many perspectives. With such a high percentage of the population trained and involved in the military the terrain was also supposed to massively aid asymmetrical warfare. Holding mountain passes with light troops if need be.

There were even some books that were discussed to become regular army manuals and had to be vetoed by the chief of staff. https://en.wikipedia.org/wiki/Total_Resistance_(book) The article doesnt cite a source, but there are other sources claiming the same. https://www.fr.de/kultur/literatur/renne-fahrzeug-weg-109971... https://blog.tagesanzeiger.ch/historyreloaded/index.php/2401...

Pls be advice that depending on local law, you might be better off sticking to the wiki page.

>Nonetheless, the book remains part of the curriculum of the Swiss Army Military Academy at the ETH Zurich as one of the "classics of the history of strategy and the theory of war."[3]
