Missouri's two biggest interstates are 30 years past their prime.
State legislators will be meeting later this month to discuss what should be done about updating I-44 and I-70.
KSMU's Matt Petcoff has the story...
I-70 and I-44 are two of the nation's oldest interstates.
And, as they cross Missouri, they carry with them hundreds of thousands of vehicles.
That traffic count, which often translates into congestion, is only supposed to increase.
Bill Stouffer is the state senator for the 21st district in central Missouri and Co-Chair of the Joint Committee on Transportation Oversight.
No major improvements to either interstate have been made in Missouri since their original construction in the 1950's.
Stouffer says these roads, in their current capacity, were meant to last 20 years and were built when the nation's population was about 180 million... it's now more than 300 million.
So, Stouffer proposes adding lanes to both 44 and 70... and not just one lane in each direction, but two.
His plan includes separate lanes for passenger cars and commercial vehicles, such as 18-wheelers.
He says adding the four lanes, instead of just two, would only increase the cost of the project by about 5 percent.
Stouffer says the eight lane proposal would be the first of its kind.
The plan would include two lanes for cars in both directions and two lanes for trucks in both directions.
The four truck lanes would be in the middle with two lanes for cars on both sides.
Trucks would only have exits at bigger stops.
Finally, Stouffer says the project could be funded by a one cent sales tax.
Tolls on both roads are one option that Stouffer says lawmakers have discussed.
He says he believes this would deter drivers from taking these routes, likely adding congestion to smaller roads and affecting business along the interstates.
It would also take a state constitutional amendment in order to place tolls along either route.
