Chinatown is a neighborhood on the South Side of Chicago, along S. Wentworth Avenue between Cermak Road and W. 26th St. Over a third of Chicago's Chinese population resides in this ethnic enclave, making it one of the largest concentrations of Chinese-Americans in the United States. It formed around 1912, after settlers moved south from near the Loop, where the first enclaves were established in the 19th century.

Archer Avenue, sometimes known as Archer Road outside the Chicago, Illinois city limits, and also known as State Street only in Lockport, Illinois and Fairmont, Illinois city limits, is a street running northeast-to-southwest between Chicago's Chinatown and Lockport. Archer follows the original trail crossing the Chicago Portage between the Chicago River and the Des Plaines River, and parallels the path of the Illinois and Michigan Canal and the Alton Railroad. As a main traffic artery, it has largely been replaced by the modern Stevenson Expressway.
