Editing Wii Moonview Highway

The course begins in an area with steep cliffs and many trees along both sides. It follows the winding road of a highway that mostly lacks guard rails and is dense with traffic, including [[Car (obstacle)|cars]], [[Cargo truck|trucks]], and [[Bob-omb Car]]s. Like in the original iteration of [[DS Shroom Ridge|Shroom Ridge]], the traffic follows the Japanese system of driving, in which vehicles drive on the left side of the road (right side in Mirror Mode). Also, the Bob-omb Cars are absent from Time Trials. The track begins with racers driving straight and immediately encountering the first set of [[Item Box]]es, and the road soon makes a right turn followed by a left turn. Along this portion of the track, racers have the option to leave the main road and drive onto some nearby cliffs, one of which has a [[Dash Panel|dash panel]] ramp at the end. Additional Item Boxes can also be found along the cliffs. As the road makes several very slight turns, all paths swiftly converge, then there is a U-turn to the right. On the outside of this U-turn is some [[Kanaami Road]] which makes it easier to avoid falling off the track. The road then makes a slight turn to the left and goes over a bridge somewhat resembling that of [[GCN Mushroom Bridge]]. The bridge contains the second and last full set of Item Boxes, but no guard rail to protect racers from falling off either side. After this is a slight right turn followed by a brief straightaway. The straightaway leads into a set of toll booths that display the course's name and are controlled by the player's [[Mii]]s. Passing the toll booths will allow the player to enter the city section.

As racers enter the city section of the track, an alternate version of the course's music will begin playing. The city itself is decorated with numerous signs and billboards, including a large billboard for "The Mushroom Moon"; if there is a Mii in the race, the faces of [[Mario]] and [[Princess Peach]] will have Mii faces from the player's console. Additionally, the Fire Flower found on a Green Fuel billboard will also have a Mii face. The layout of this section is entirely composed of three straightaways with two right turns in between. Individual Item Boxes can be found throughout this section, but they are always quickly moving. The highway itself is now four lanes, with two on each side, and fully covered by walls that show a pattern of [[Shy Guy]] and [[Bowser Jr.]] faces. Various dash panels litter the track, a few of which span the width of the entire road. The vehicles from before now move about three times as fast, and they will constantly change lanes to avoid running over any dash panels. Towards the end of this section, racers enter a tunnel which has pillars in the middle of the road, serving as additional obstacles. After exiting the tunnel, racers pass through another set of toll booths and reach one more brief straight where the finish line is located. As this happens, the course's music returns to its default version.

Unlike every other Wii track, this track does not feature any notable shortcuts. In conjunction with the track's frequent obstacles and dash panels, this greatly limits the utility of some speed items. However, items that provide the player with invincibility can still be of great use.
