My hometown in the US still does it like that! And they’re stunningly efficient. There was one time we had to go around an enormous detour because the biggest road in town was being redone in like a 2 mile stretch. They did the entire thing overnight in one giant marching construction worker swarm. A few towns over from us did something similar earlier this year but with their local stretch of highway. It was maybe a 15 mile redo all at once took just a few days (they did one lane traffic on one side than the other for that one, small highways). Compare that to where I’m at in Seattle right now Madison has been fucked for like 2 years and I swear none of the roads have actually been resurfaced it is just one construction patch after another when like a pipe needs fixed or something.
