Left Exit Wrap Under Own Section

Gallery / Inter-section Routing

A LEFT exit feeding a RIGHT entry up and two columns across: the wrap leads out on the exit's own side, passes under its section and climbs into the entry, instead of running back along its trunk over the stations it has just served (#2073).
