Though Greenwood was thriving in the mid-20th century, another threat to the community’s prosperity loomed on the horizon: urban renewal. With the construction of an interstate highway right through the middle of the district, residents were forced out of their homes, and many moved north. When the city began to integrate, the insular economy that had sustained Greenwood for so long spread out all over Tulsa, forcing Black business owners to close up shop. For those who grew up in this technically integrated — but still socially segregated — Tulsa, the Black Wall Street of the past was no more.
