The higher the density, the more problematic to dig up the streets to bury the fibre lines. And US streets are much wider to dig the lines.

I've seen city-level street works in the US and they are incredibly slow compared to national highway work, or street work in Europe. Like 10x slower. And getting the permissions? Impossible

You don’t need to dig up streets to install fiber underground.

		You often do, if the street has been there for a while. The exact location of underground infrastructure was rarely documented in the past. While the city should have a general idea of what lies under the street, you usually have to dig the street up to determine where you can install new infrastructure safely.

		Well, that's "small" digging, but you still need maps and permissions.
