SELINSGROVE SPEEDWAY: A Motorsports Tradition for Generations

Selinsgrove Speedway’s grand motorsports tradition began July 20, 1946, when Bill Holland of Philadelphia won the first race. Since that historic day, Holland went on to win the 1949 Indy 500, and many of motorsports’ most famous drivers have turned laps at the iconic half-mile dirt track designed by legendary Hollywood stuntman and race car driver Joie Chitwood. The speedway, celebrating its momentous 75th anniversary in 2021, will continue its legacy of rip-roaring open wheel and stock car racing this season and for future generations!
