The intersection of Houze and Hembree roads in Roswell looks a little different than it did two years ago.

Folks who haven’t been to north Fulton County since then might notice a big round block of concrete in the middle of the intersection, with cars flowing around it.

The roundabout at the intersection is now fully operational, the city says. Work on the project began about 21 months ago and cost $4.4 million. Of that cost, $353,500 of was paid by Roswell.

Before work began, the intersection was a standard four-way one with stoplights. Now it’s a two-lane roundabout.

The city posted a video to its Facebook on Tuesday, showing drivers how to use the roundabout.

One commenter suggested a roundabout for the intersection at Warsaw and Old Roswell roads, while another suggested tearing out all roundabouts and replacing them with stop lights and turn lanes.
