LOUISVILLE, Ky. (WDRB) -- Some are old, some are bright, others are loud, and they're rolling into Louisville as the Street Rod Nationals return.

More than 15,000 street rods and vintage cars are expected for the show.  It runs Thursday through Sunday at the Kentucky Expo Center.

This is the 19th year it's been in Louisville.  Some of the cars were on display Wednesday at Fourth Street Live.

The Street Rod Nationals are expected to have an economic impact of more than $13 million on the area.
