BX was excited and privileged to work on the first roundabout on the South Dakota Department of Transportation managed highway system.  Roundabouts have been built in other parts of the country and world and have been used in South Dakota on a select few city projects in other communities in South Dakota.  This roundabout was however significantly larger and sized to accommodate heavy truck traffic that is encountered in that intersection especially due to its proximity to the Glacial Lakes Ethanol Plant.  The roundabout was constructed entirely of concrete and utilized colored concrete in the center circle and in each quadrant to give visual impact and guidance to help improve the safety and traffic flow.
