The costs to build a roundabout isn’t much different than a standard intersection with a traffic light — about $1 million to $1.5 million.
MnDOT is aware of the work it needs to do in educating the public about why roundabouts are being used. In May it hosted an open house to talk about new roundabouts planned for Highway 22 and Adams Street and Highway 22 and Madison Avenue, in addition to talking about roundabouts in general.
Their staff set up stations to show and explain how the roundabouts work with maps, a floor model and even a table-top roundabout using toy cars to demonstrate how they work.
Drivers need to take time to learn about the roundabouts as they become more common in Minnesota, and all driver education instruction should include coverage of the topic.
Roundabouts may be a strange concept to motorists who are used to stoplights and stop signs, but if lives can be saved and traffic flows more smoothly, this traffic-control method should be welcomed.
