Atlanta Motor Speedway has postponed its July 4th Papa John's Pizza Fireworks Extravaganza to July 25th as a result of inclement weather.

The fireworks display, the largest on Atlanta's south side, will now take place as part of championship night at Thursday Thunder, Atlanta Motor Speedway's grassroots short track series.

Scheduled feature races from week five of Thursday Thunder will be made up on July 18, giving drivers two rounds of double features in a row on the quarter-mile Thunder Ring. Double features are also scheduled for Thursday, July 11.

Tickets to Thursday's race will be accepted for any remaining week of Thursday Thunder, which concludes July 25.

Each week, Thursday Thunder will present an interactive experience for families, with concourse activities such as face painting, woodworks and more. Every Thursday Thunder event will feature an autograph session with competitors. Plus there will be contests and games for spectators to participate in while in the grandstands, like a Root Beer Chugging contest, trivia, dance contests and more.

Tickets for the affordable, family-friendly racing series costs just $6 for adults, $2 for children ages 6 through 11 and is free for children ages 5 and younger.
