BOONE COUNTY, Mo. - UPDATE (3/23 6:00 p.m.): The Missouri Department of Transportation officials said Route O could be due for safety upgrades in the next few years if funding comes through.
District engineer Mike Schuup said since MoDOT has limited funding, Route O isn't currently in its five year plan but if he is able to secure funding, they'd like to add some improvements to the often treacherous road.
"It's going to have a new surface," he said. "It'll have edge line rumble strips and a two foot shoulder, which will help with the feeling as you're driving the road."
They've tried to make it a little safer in the meantime. There are warning signs about hidden intersecting roads and driveways. Schuup said they don't allow passing on the road.
"Pretty much the entire road is striped a double yellow," he said. "It's a no passing road because there's just not enough sight distance due to the hills and curves."
Until they're able to make improvements, Schuup said drivers should drive for conditions which includes obeying the 55 miles per hour speed limit, and always wearing a seatbelt.
"Distracted driving is a huge cause of accidents," he said. "Two thirds on Missouri roadway fatalities are unbelted."
