Lr Perpendicular Ports Overflow

Gallery / Inter-section Routing

A RIGHT exit feeds the TOP entry of an LR section directly below it. The entry port sits on the column reached by the exit's turn runway, so the route makes one turn and descends continuously through the section boundary instead of jogging sideways at the port.
