11-year-old Jolie Allen from Nevada City has been working on a project to make Highway 49 safer.

Her passion started after two teens, Joe Rantz and Jude Douden were killed in a car crash on the highway in December 2016.

"You pray this never happens to you children and in a moment he was gone," said Annie Rantz, Joe's mother.

Allen has created buttons, passed around hundreds of them to groceries stores and gas stations.

Thousands have even signed her petition.

The 11-year-old wants the highway between Grass Valley and Auburn safer by adding a median barrier with CHP increasing patrols and speed enforcement.

She presented her project to Cal Trans, CHP, and local leaders on Wednesday at Bear River High School in Grass Valley.

"I think it'll make a different and have the community involved," said Rihui Zang, Cal Trans.

Zang said they've made changes over the years like adding a passing lane but even with any future changes there's no guarantee.

"Making changes to the roadway may not solve the problem because at times it has to do with driving and the conditions," said Zang.

There are some people who worry that changes to this highway could impact them negatively.

"I do think it would cause problems on the road, maybe more traffic, and not being able to turn certain areas," said Corey Waldman, Grass Valley resident.
