Garfield Boulevard is an east-west street on the south side of Chicago and its immediate western suburbs. Its western segment, entirely known as 55th Street, runs east from Maple Avenue in Downers Grove until it becomes Joliet Road in Countryside. Its eastern segment, known only as Garfield Boulevard from Western Avenue in Gage Park to Elsworth Drive in Washington Park, runs east from Archer Avenue and Narragansett Avenue to South Shore Drive, just west of U.S. Route 41 (Lake Shore Drive). All of the eastern segment of 55th Street lies within the city limits of Chicago. From Wikipedia
