Fourteen trees were broken in half in a median along the road earlier this week, costing more than $7,000 to replace.
Officials say it wasn't easy planting the Japanese Lilac trees as they had to be approved by the Iowa DOT before planting.
"You can't just have any kind of tree out there in the median of a highway like Kimberly Road," said Mike Clarke. "It's species specific and costs a little more money to get them it. They were maturing nicely, so we're disappointed they were destroyed."
The trees were originally purchased through a grant and the city says it doesn't have the funds to replace the them right now.
