When the Kentucky Speedway was built in 1998, officials predicted it would dramatically change Gallatin County and have a huge economic impact on the state. A wave of development was expected to sweep through the area surrounding the speedway, transforming its rolling green hills. That never happened, chiefly because the speedway never received the NASCAR Sprint Cup Series race for which it was built. That race will finally come on July 9 - and some are again predicting a tidal wave of economic activity, especially in Gallatin County.
