1959 - RIVERSIDE PARK SPEEDWAY
Riverside Park Speedway opened as a roughly graded 1/4 mile dirt oval track. The program would consist of Stock Cars and on occasion Modified's.
The speedway was part of a fun park complex, so most of the racing would complement other festivities.

1964 - RIVERSIDE PARK SPEEDWAY
In 1964 heavy rains caused the Palouse River to flood, this was devistating as most of the buildings and amenities were destroyed, it was all a bit to much for the owner, so he closed down the park and removed everything off site.
