1931 - TROY HILLS SPEEDWAY
Troy Hills Speedway was a 1/3rd mile dirt oval track that opened in 1931 and closed in 1934, During its life no fatalities were recorded.
The surface at Troy Hills was coated with a mixture of mine dust and oil, This coating supressed any that was normally associated with dirt track speedways, possibly the reason why the track had such a high safety record.
Troy Hills was one of the first east coast tracks to install electric lighting.
