To clear a table is to leave nothing on it. That is the sense the word carries over, and it is why the word was chosen.
Detroit called it clearance, and clearance sounds like housekeeping. Hastings Street was Black Bottom’s business district, and the city built I-375 in its place.
Watch what the word does to the sentence. It takes an act with a hand behind it and turns it into a condition of the ground. Nobody clears. The land simply becomes clear.
