An express lane is pictured in this video screenshot from the Colorado Department of Transportation. The Kansas Department of Transportation opened express lanes on a six-mile stretch of U.S. Highway 69 in Overland Park — the first of their kind in the state.

Members of the public have been given a little bit of extra time to comment on possible changes to Kansas Highway 10 that could include the addition of tolled expressway lanes.

The Kansas Department of Transportation has extended through Friday the public comment period on its study related to the capacity of K-10, which runs between Lawrence and Johnson County.

The study is examining a host of potential projects that could help the already busy highway handle more traffic. The corridor is expected to see an increase in traffic as Panasonic completes a $4 billion, 4,000-job electric vehicle battery plant in De Soto.

Among the ideas under consideration by KDOT is a widening of the four-lane highway to six lanes. KDOT has said it is interested in having the two new lanes be tolled expressways, meaning motorists would be charged a fee to travel in those lanes. The existing four lanes of the highway would remain free of tolls.

Members of the public can learn more about potential projects for K-10 by joining the virtual meeting that KDOT currently is hosting. Once in the meeting, people can leave their comments about the study and potential projects. To join the meeting, go to k10.ksdot.gov.
