The multilane roundabout at Warren Parkway and Ohio Drive is complete and will open to drivers at 9 a.m. April 9. All roads and lanes that were closed during construction of the roundabout will also be open April 9. The roundabout is similar to the one at Gaylord and John Hickman parkways. The city of Frisco has put together an informational page with diagrams and a video of how to drive a multilane roundabout. Click here to see more.
