At the end of the conveyor belts there is a slope with alternate Boosts (that turn on and off through time) and at the end of it are two gliding pads.

It contains conveyor belts with opposite directions that changes over time, like Toad's Factory from Mario Kart Wii. A gliding pad is found after the anti-gravity section and leads to the second space station with a large imprint of Mario's 'M' emblem. After a turn the drivers find the first anti-gravity section, that is 8-shaped. The course starts with the rainbow-colored tiles. The staff ghost kart setup is Pink Gold Peach driving the Comet with Slim wheels and the Super Glider.

The colors are somewhat similar to the Rainbow Road from Mario Kart: Double Dash!!, with its prominent pink, magenta, and cyan shades. The road is made up by what appears to be long lines of solar panels, with the rainbow coming from starlight reflection. This is a very unique Rainbow Road, taking place in a large space station and heavy use of the anti-gravity feature, as well as entirely different theme and a vast amount of futuristic design in contrast to the previous variations' fantasy-esque settings. This incarnation returns to the classic three-lap format after Rainbow Road in Mario Kart 7 featured one long lap divided into three sections. Unique from its predecessors, it takes place in a space station, which is given a new metallic design, as opposed to the transparent glass surface of previous games. Rainbow Road, the last course of the Special Cup in Mario Kart 8 and Mario Kart 8 Deluxe.
