FEDERAL AID HIGHWAY ACT 1956
Federal Aid Highway Act of 1956 sanctioned the creation of a state-funded highway system subsidizing "white flight" from the city, demarcating neighborhoods along racial lines, destroying African American neighborhoods, and transporting jobs out of urban areas.

EXAMPLE
I-375 is a 1.06-mile spur that pierces Detroit's downtown. Begun in 1959, this 4-lane, below-grade freeway disconnected Detroit's Riverfront, Greektown, Eastern Market, and Stadium districts. Its legacy is tied to failed urban renewal efforts that destroyed thriving black bottom district & neighborhood.
