The 143rd running of the Kentucky Derby is less than a week away, but the commonwealth already hit big on a trifecta in terms of economic development. Only four months into 2017, Kentucky has already announced $5 billion in corporate investment, thanks to billion-dollar projects by Amazon, Toyota and Braidy Industries, in addition to more than 50 other business-expansion and new location projects. The achievement puts the state on the brink of its all-time, full-year record of $5.1 billion, set in 2015.
