JEFFERSON COUNTY, Mo. (KSDK) -After feeling like he had nowhere to turn, Shawn Archambault found his direction.

"If you knew her you'd know why I do the things that I do," he said.

Archambault, from Eureka, Mo., has dedicated the last three and a half years of his life to the memory of his daughter, who he describes as smart and silly.

"When she walked in a room, she lit up the room," he said.

Kaela was a 20-year-old Eureka High School graduate who was hoping to one day become a nurse.

She was on her way to work on a November morning in 2010 when she lost control of her car

slamming into a stopped school bus. Five children on the bus suffered minor injuries but a police report said Kaela died instantly.

"She wasn't in a rush, " Archambault said. "She wasn't late for work And she had plenty of time to get there."

It happened on HWY FF near Eureka, a dangerous stretch of road that has seen over a hundred crashes in the last seven years. This road has a crash rate 25 percent higher than the statewide average for a two lane road.

"Every time I drive home if it's raining or snowing you can almost expect three or four cars in a ditch," Bain Turnbo said.

When the 21-year-old Turnbo travels this stretch of road, he thinks of his mom.

"She was like the most loving person I've ever met in my life," Turnbo said.

Karen Turnbo died in a single-car crash just a short distance from where Kaela lost her life.

"She was on her way to bible study in the early am and she lost control and hit a tree," he said.

Highway FF was built in the 1950's as a farm to market road with sharp curves and no shoulders.

In other words, no margin for error.

"It just takes one tire to come off a hair of an inch, "Archambault showed us along the road.

So, in the wake of Kaela's death, Shawn picked himself up and then picked up the phone. Judy Wagner was on the other end and she had received a few of these calls before.

"But this one was a little different. He wanted to make a difference, "she said.

Wagner is a engineer with the Missouri Department of Transportation. She's very familiar with the dangers of HWY FF and the thousands of miles of Missouri roads just like it.

"Today this is carrying over 3,000 cars a day and back then it carried maybe 3 or 5 a day, "Wagner said.

With Wagner's help, Shawn started an organization called One Curve at a time. Their mission to build awareness of hazardous highways like FF and then to petition Missouri Highway Commissioners to fund change.

For Wagner, Shawn's passion moved the effort from professional to personal.

"You know I look at my daughter who is 20, "she said through tears. "It could have been her. One fatal mistake. And it means the most to me to build this job."

Where there is purpose there is power. After Shawn attended dozens of city, county and state meetings, the One Curve at a Time organization unveiled a billboard along Hwy FF in honor of Kaela.

And later this month, there will be a groundbreaking ceremony for $1.7 million in road construction improvements.

"It's giving me a piece of Kaela back," Archambault said.

Kaela was only in this world for a short time but now in a way she will live on forever. In her memory even if they never know it ,drivers on Highway FF will be safer every time they travel on Kaela's curve.

"It's going to be an awesome thing, "said Turnbo, "to see people stop losing people to this road."
