City crews have been rebuilding and changing the landscaping on roundabouts on the West End in an effort to make them easier to maintain.
The idea is to make them "a lot less weed-by-hand," said Debi Meling, city engineer.
In all, six roundabouts on Shiloh Road — from Hesper to Broadwater — will get the makeover. Less greenery on the roundabouts means the city spends less money on maintaining landscaping and keeping plants alive.
The large rock structures are designed to improve traffic safety, Meling said. The rocks prevent drivers from seeing too far down the road and focuses their attention on the traffic moving around the roundabout itself.
"Drivers just need to see people coming from their left," she said.
