they demolished a medium density neighborhood for highways so suburbs can commute in and out of inner city. when you destroy neighborhoods and create “green space”, people don’t just stop existing. they either get pushed to the suburbs if they can afford it, or (most likely) the ghettos.

and how does highway create public transit?

highway is a mechanism to separate the undesired that cannot afford cars. kill a few lanes and build trains would mean “those people” can reach “our neighborhoods”.
