Sewer Speedway (ハイスピード ちかすいどう lit. High Speed Underground Sewer in Japanese) is the fourth race course in Crash Team Racing and it is based on the sewer-themed levels in Crash Bandicoot 2: Cortex Strikes Back. It is in the Blue Gem Cup (joining Tiger Temple, Dragon Mines and N. Gin Labs). It's also much longer than other tracks at the early stage of the game.
