This type of interchange is proposed on I-75 and University Parkway.
Below is a link to the video that was shown regarding the diverging diamond concept. The video is about 8 minutes in length and I would definitely recommend watching it if you have the opportunity. It will be constructed at I-75 and University Parkway in Sarasota and Manatee Counties.
