The Martin Luther King Jr. Parkway is a 7.1-mile (11.4 km) long expressway running along the eastern and northern edges of Downtown Jacksonville, Florida.

Despite its name, it is not a parkway in the conventional sense, as it has no limits on truck use and is not located near parks or other beautified areas.

Continuing north around downtown Jacksonville, the highway bends due west and intersects Interstate 95 (I-95).

The eastern portion, running due north from the base of the Matthews Bridge, was known as the Haines Street Expressway.

[4] Jacksonville was one of the last major cities in the country to rename a road for Dr. King; by choosing this route, the city was able to pay homage and yet because the entire route is without any addresses, either residential or business, the council was able to avoid irritating constituents, as often happens with such name changes.
