In cities across the country, many streets bear the name, Martin Luther King Jr, after the former civil rights leader.
Now Tulsa joins the rest of them with new signage that marks the change.
The name change affects Cincinnati Avenue from Archer to 65th Place North.
The name change was approved by the city council several months ago, but the money wasn't there to make the changes.
Now it is.
For at least some Tulsans, the change to Martin Luther King Jr. Blvd will not come easy.
"I've been here so many years, I probably still say Cincinnati," says 101-year-old Willie Thompson.
But, Thompson also says she thinks it's a wonderful gesture. She says, "They need to name something after him, because he was very intelligent, smart, worthy."
For Alice Johnson, the new signage signals progress in the African American community. "I am so excited. I cannot believe Tulsa had not had a city, a street named Martin Luther King Jr. Blvd. This is exciting, this is historic, we are excited about it."
Johnson is the director of the Tulsa Residential Center, which sits on the newly-named street. The address change means a lot of leg work for people and businesses there.
She says, "We had a smooth transition with our business card, our letterhead and even allowing our clients our offenders know so that they can have that notice so they can notify their family as well."
The U.S. Postal Service has known about the change for awhile.
The signage changes cost the 100-thousand dollars.
