CT Jam Festival is Justin's tenth custom track. The track takes place in a festival themed around the Custom Track Jam competitions celebrating the winners of previous contests. The racers begin in a gallery with pictures of previously submitted tracks. After exiting the building and driving through an outdoor beach-side area, the racers have to navigate through the three first tracks that won their competitions: Mouse Hole Mania, Maple Realm and Coin Heaven. It was created for the 17th edition of BillyNoodles's Custom Track Jam, where it placed third.
