Trivia

 * Of all the stages in Sonic Generations, this stage is the only one that Sonic was never playable in. Shadow the Hedgehog ventured through this stage instead.
 * Even though Sonic was never playable in Radical Highway in Sonic Adventure 2 story-wise (he was playable on the multiplayer racing mode), he has been there at least 2 times: During the intro of Sonic Adventure 2 and Mario & Sonic at the Olympic Winter Games (Dream Snowboard Cross)
