The move enabled not only construction of modern grandstands and a pressbox, but also provided room for an adjacent campground for racing fans.
The grandstands are still visible, as is much of the milelong oval track.
After an engineering study of the north-side and south-side grandstands, the south-side stands were condemned.
The grandstands and bleachers were expanded to seat 18,000.
Still standing as of 2012, the grandstands were built from 175,000 board feet (400 m) of lumber with a capacity of 5,500 spectators.
Other improvements have included a complete refurbishment of the stadium grandstands, building and fields in 1990.
The building has four grandstands (one of them exclusively for members).
However, even though its grandstands have been extended in the late 1990s, currently it seats 27,650 people due to regulations enforcing improved safety and comfort.
