The fair and rodeo will be held Oct. 22-24 in the Williamson County Expo Center in Taylor, said Scott Heselmeyer, president of the rodeo's executive board.
Heselmeyer, who said he grew up in Williamson County, said he felt there wasn't a singular event that included a rodeo, carnival and county fair in Williamson.
"We just want to have a good family, fun experience, that is the main idea," Heselmeyer said.
Tickets are not yet available and the price range has not been set, but Heselmeyer said they will likely be available in March.
During the kick-off event, Heselmeyer listed other activities attendees can expect, including a Cowboy's Professional Rodeo Association/United Professional Rodeo Association rodeo with bareback riding, steer wrestling, team roping, bull riding and more. There will also be a kids mutton bustin', calf scramble and drill team on horseback, he said.
A carnival with rides, pig races and a petting zoo will also be featured, as well as a vendor fair, farmers market, wine and beer garden, livestock show, and patriot pro mustang showdown to round out the three-day event.
More event details will continue to be released as they are finalized, Heselmeyer said.
The Williamson County Commissioners Court approved an agreement in December with the Williamson County Fair Association to give $100,000 in seed money for the fair, which will be reimbursed over four years.
The Expo Center broke ground in 2015 and opened in 2016. It was built with voter-approved park bonds.
"This is something [former County] Judge [Dan] Gattis and I started talking about 5 or 6 years ago," Heselmeyer said. "And now that we have this [new facility], we now can see this dream become a reality."
