Antique & Classic Car Show Returns to the Riverfront

Vehicles ranging from the Model T to vintage roadsters to modern marvels will be on display at the Sioux City Museum and Historical Association's 53rd annual Bill Diamond Antique & Classic Car Show on Sunday, July 12. The event is free and open to the public from 11 a.m. to 2 p.m. on the grounds of the Sergeant Floyd River Museum & Welcome Center on the riverfront. This is a Show and Shine event; pre-registration is not required.

Music will be provided by DJ Big Daddy from Classic Rock 95. Big Papa's Grub on the Run and Patti's Pit Stop food trucks will have a variety of concessions available for purchase.

The Sioux City Museum & Historical Association renamed the car show in 2004 to honor the event's co-founder and long-time director of the Sioux City Public Museum, Bill Diamond. The car show was started in 1970 at the Sioux City Public Museum site as part of a temporary exhibition. The event proved to be so popular that it was continued and eventually moved down to its current location on the riverfront.

The Sergeant Floyd River Museum & Welcome Center is located at 1000 Larsen Park Road via I-29, exit 149 in Sioux City. For more information, contact the Sergeant Floyd River Museum and Welcome Center at 712-279-0198 or visit SiouxCityMuseum.org.
