History
As early as 1930, the road was named Wall Street in the city limits of Fayetteville. The road later became 6th Street. Between 1971 and 1989 this road was designated US 62 Business.

On January 15, 2009, Fayetteville renamed Sixth Street to Martin Luther King Jr. Boulevard. The ceremony took place at the Razorback Road intersection at the entrance to the University of Arkansas. Most Fayetteville businesses on the road still claim 6th Street, and many residents and university students continue to call the road 6th Street over two years after the change.
