Hubbard Street is a street in Chicago, Illinois named for early settler Gurdon Saltonstall Hubbard. Hubbard Street has three distinct sections. The first, east of the Chicago River, runs from Kingsbury Street to Michigan Avenue. The second, longer section runs from Des Plaines Street west to Campbell Avenue (2500 W) The third and shortest section is a three-block stretch from Kilpatrick Avenue (4700 W) to Lavergne Avenue (5000 W) where it ends at the Hubbard Playlot Park. Notable buildings on this street include Courthouse Place at 54 W. Hubbard. Hubbard's Cave Where Hubbard Street crosses over the Kennedy Expressway, there is a long underpass popularly known as Hubbard's Cave. The underpass is about a quarter of a mile in length, and actually extends from Hubbard Street to Wayman Street. This tunnel-like section of the expressway was very dark to drive through until lights were added in 1962. Murals Running along the south side of Hubbard Street, from Ogden Avenue to Des Plaines Street, is the artwork of the Hubbard Street Mural Project. The murals are painted on the walls of the Metra tracks embankment. Originally begun in the 1970s, the murals have been in the process of restoration or replacement as the Union Pacific Railroad has been making repairs to the concrete structure.
