On a recent trip to Florida I ended visiting Siesta Key and former Florida State Road 758. FL 758 sans the Sarasota Bay Bridge was recently relinquished via transfer agreement to Sarasota County during September 2020 west of US Route 41. Interesting I found FL 758 to still be fully signed west of US Route 41 along with the westernmost stub of FL 72.
