Post-World War II, there was a real estate development boom in West Orange. In the 1960s, "white flight" from the 1967 Newark riots and Civil Rights Era led to further settlement of West Orange. The 1970 opening of Interstate 280 made West Orange a popular "bedroom community" suburb for commuters to New York City. This coincided with changes to immigration laws re-opening the country to Asian immigration in 1965, and 1980s desegregation of American suburbs. By the 1990s, West Orange had become a "melting pot", home to a diverse and international community. Many of the industries that had made West Orange grow, left the area by the 1960s. This left some urban blight and abandoned warehouses in the Valley, in contrast to wealthy communities on top of the mountains.
