Mario & Sonic at the Olympic Winter Games
Radical Highway made an appearance in Mario & Sonic at the Olympic Winter Games as the Dream Event location for the Dream Snowboard Cross. It appears similar to that of its original appearance, featuring the large suspension bridge, yellow lighted tunnels and large shuttle loops. While some elements remained the same, some changes were made to the stage such as a constant downhill appearance and the enemies that appeared.

Trivia

 * In Sonic Adventure 2 and Sonic Adventure 2: Battle, Shadow was the only character playable on Radical Highway (unless it was during multiplayer mode of the later game). On the Event Select screen of Winter Games, Shadow was the one shown in the small image of Dream Snowboard Cross.
