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. It carries U.S. Route 1 Alternate (US 1 Alternate) from near its southern terminus to an interchange with US 1/US 17 (Main Street). US 1 follows the expressway to its northern terminus, an intersection with US 23. 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.
