A 2015 study funded by the state of Iowa recommended the City of Knoxville make changes to Highway 14/Lincoln St. to make it more efficient.

The project, called a road diet, means that the road will be thinned to one lane travel for each direction, with a middle turning lane and bike lanes on each side. Knoxville City Manager Aaron Adams tells KNIA/KRLS News commuters should see improvement in their travel on the road with it being both more efficient and safer to drive on, especially with its proximity to the Knoxville Middle School. The plan for the road diet is still being put into place, with hopes of implementing the project by 2020.
