For some who drive down the highways in Tennessee, the aesthetics of the grass and accompanying elements of nature are of importance. An interested motorist wanted to understand more about the upkeep methods undertaken by the Tennessee Department of Transportation (TDOT). As part of this accompanying video, TDOT Spokesperson Heather Jenson explains.

“We operate on a cycle system. We have five cycles for interstates, four cycles for state routes,” she explained. “We have to do that because it’s the best use of our resources but also the money we have available.” Jensen went on to say that means interstates get cleaned up about once a month.

She said as much as they want the same clean look, other things can get in their way, making it harder to keep up. “We’ve had a pretty damp spring and we’re technically not in summer yet, but we’ve had a pretty damp couple of months,” Jensen said.The rain makes the grass grow a little bit longer before the next mowing cycle comes around.
