No injuries have been reported. The area around Buc-ee's was blocked off Monday, and people were asked not to turn into the store from Highway 183, the Inquirer reported.
Multiple fire departments responded to provide assistance, and they said that the fire was not expected to endanger the new Buc-ees location, which the company calls the world's largest.
Buc-ee's opened the original Luling travel center in 2003. It closed June 10, and the new location opened nearby the next morning.
The newly opened Luling location has twice the square footage of the original travel center, making it the biggest Buc-cee's yet. The new location occupies more than 75,000 square feet and will offer 120 fueling stations and thousands of food and drink options.
