Street Guide and Metropolitan map of Detroit

By the mid-20th century, progressive Detroit leaders boasted of the city's modern freeway system. The I-375 freeway, the southernmost spur of Detroit's Chrysler Freeway, was marked out on this map with a dotted line. When completed in 1964, this freeway contributed to the almost complete obliteration of the once-thriving African-American neighborhoods of Black Bottom and Paradise Valley.
