Muhammad Ali Boulevard

The street is also formerly and less commonly known as Walnut Street east of 28th Street, including the entire downtown section, and Michigan Drive west of 28th Street. These names correspond to the old names of the street prior to its renaming in 1978.

The street carries one-way westbound traffic only across its entire length. Muhammad Ali Boulevard is a couplet with parallel and eastbound Chestnut Street and River Park Drive. However, through downtown, Liberty Street is a closer opposite-direction one-way street, and parts of Madison and Vermont Streets provide intermediate two-way parallel traffic flow over some parts of the route.

Major intersections

The entire route is in Louisville, Jefferson County.
