Sure, NASCAR is going from a 15-turn road course in Mexico to a familiar old track in the Pocono Mountains, but Pocono Raceway isn’t your typical stock-car oval track.

Pocono takes the “tri-oval” concept to an extreme.

Track construction began in the mid-1960s, six years after the opening of Daytona International Speedway brought a whole new tri-oval to racing. Pocono would become more triangle than tri-oval, however, with three distinctly different turns.

Pocono’s track was designed by Indy-racing legend Rodger Ward, who modeled each of three turns after turns on famous tracks in the Indy world: Trenton Speedway (Turn 1, 14 degrees of banking), Indianapolis (Turn 2, 8 degrees) and the Milwaukee Mile (Turn 3, 6 degrees).

Practically all forms of big-league auto racing have raced at Pocono, including, since 1971, NASCAR. The tradition continues this weekend, and here’s how to watch, including Prime Video’s fifth and final broadcast of its five-week run of Cup Series coverage.
