At our November meeting, the Florida DOT showed us several potential turning solutions to the traffic woes at the intersection of Alt US 19 and Curlew Road. Among those was the Divergent Diamond Interchange. Here is a simulator game that will allow you to drive through the different parts of a Divergent Diamond Interchange. The other links will take you to more information about the designs or to locations that have or are planning to construct these new designs.
