Once a multi-ethnic, economically diverse city, Orange suffered indirectly from the 1967 riots in Newark (even though Newark and Orange do not share a border) and directly from the construction of Interstate 280 through the heart of the downtown area, triggering middle-class "white flight" from aging industrial towns to the new automobile suburbs being built in western Essex County and elsewhere. By the end of the 1970s, Orange had many of the urban ills normally associated with larger cities. However, the city still features many tree-lined streets with well-maintained homes.
