A little girl has made a big change in her city by writing a letter to officials requesting more inclusive signage near construction zones.

Vivian Anderson, 10, a fourth grader from Tampa, Florida, mailed her inquiry to Mayor Jane Castor, last December after seeing a "Men Working" sign while in the car with her mom.

"We were in traffic and she said, 'Mom, why is there a sign that says 'Men Working' but men and women are both working?'" Vivian's mother, Mary, told "Good Morning America." "She said, 'That's no fair. How do we fix that?'"

"I told her, 'As luck would have it, we happen to have a new mayor who happens to be a woman. Maybe she will like your idea,'" her mom said.

On Aug. 21, Vik Bhide, the city's mobility department director, replied to Vivian's letter agreeing that the sign should be more inclusive. Bhide also noted the workers may have been private contractors and not a city crew.

"She was very excited," her mom said. "I think it gave her a lot of confidence that people will listen to kids. Kids can make a difference."

Vivian told "GMA," "It's a little overwhelming but I really liked meeting the mayor and I do really like how my sign made a change."
