"We think its a critical time in Missouri's transportation to be able to keep moving forward with the funding and basically provide what the people are asking for," said Tony McGaughy, an Assistant District Engineer for MoDOT.
Voters will need to approve a 3/4ths of a cent sales tax in August for the improvements to happen.
It's something MoDOT says is desperately needed for the state.
"It's one of those things where we are at a critical junction as far as funding," McGaughy said. "We're barely able to maintain what we have and actually looking down the road, it doesn't look like we're going to have the funding to maintain the system that we have now."
One hundred and thirty five projects have been approved for Northwest Missouri, mostly for bridge and road improvements.
Among the proposals - bridge repairs at 36 Highway and Riverside Road, interchange improvements at I-29 and 169 Highways, and road resurfacing and shoulder improvements on Route 6 just east of St. Joseph.
"The traffic gets more and more all the time," said Frank Laffargue.
Laffargue owns Quality Auto Repair on Route 6. He says he would welcome the improvements.
"The wider the road is, the better," he said. "A lot of these are blind crossings when you come up over the hills, you can't see coming up until the last minute."
Laffargue says improvements to the road could also mean more business for his shop.
"It'd be safer," Laffargue said. "Make it a lot more pleasant for our customers."
MoDOT says if voters approve the tax, the projects should be completed within ten years.
But if the vote fails they say the same amount of work could take decades.
