I was reading about the restricted crossing u turn intersection (known by some as superstreet intersections) in which a road near Disney in LBV, FL is constructing 4 of them.
I was wondering if the terminology of RCUT is used in your area, as well as the installation of these. Or does your area use a different term for these intersections explained here http://onlinemanuals.txdot.gov/txdotmanuals/rdw/rcut.htm ?
Called J-turn or Michigan left around here

Here is an article by FHWA, using the Michigan Left term in addition to J Turn.
There are only a couple in Wisconsin. This one was constructed about 10 years ago, but will be upgraded to a diamond interchange in the next couple of years. WISDOT refers to it as a RCUT.

RCUTs are technically different form Michigan Lefts, despite the similarities in having restricted movements and median U-turns.
A Michigan Left intersection involves two roads only allowing straight-through and right-turn movements, and using downstream median U-turns (on either street, or maybe both in a few cases) as an alternative to the left turns.
An RCUT intersection allows left-turn, straight-through, and right-turn movements from the major road, and only right turns from the minor road. Median U-turns are provided on the major road to facilitate the straight-through and left-turn movements for the minor road.
A couple of RCUTs in my area:
US 50 and MO 58: https://goo.gl/maps/e8GUTKuMcXhQS4iA9
US 50 and MO 131: https://goo.gl/maps/iDv7rrdEEaUZLa6W7 (Needs updated satellite imagery, but you can tell from Street View.)

I think I saw those on the expressway section of US 63 from Columbia to Jefferson City. You had to make U turns to get back north from the side roads.
Kentucky is installing RCUTs with increasing frequency as safety improvements, and seems to prefer that term to J-turn.
Public outcry recently caused KYTC to scrap plans to build one on US 27 at KY 70 in Pulaski County in favor of a signal.
