Easier to clean up the mess
“It has been established, for example, that suburban streets all over America ought to be as wide as two-lane county highways, regardless of whether this promotes driving at excessive speeds where children play, or destroys the spatial relationship between the houses on the street.

And in the aftermath of a war, it was believed, wide streets would make it easier to clean up the mess with heavy equipment.”
