Median U turn segments in Metairie
Median U turn segments

Dedicated median U turn segments in the New Orleans metropolitan area (at least) shall be unnamed.

A turn instruction override should be used such that a "U turn" instruction is given when entering the U turn segment.

For curved segments, the geometry of the segment should be set such that no instruction is given when leaving the U turn onto the road. For straight segments, a turn instruction override may be used as well, set to "None".
