1978 YELLOW RIVER SPEEDWAY
The land that Yellow River Speedway was built on was originally phurchased in 1972, the building of the track was the project of James Langreck from Marshfield and took five years to build.
The Speedway opened in late 1978 as a 1/2 mile dirt oval track, 12 months earlier the nearby Neillsville Speedway had closed so there was a need for the new speedway.
In about 1995 the speedway went through a major transformation from dirt to a 1/2 mile paved surface and was renamed Marshfield Motor Speedway.
