A lot of large companies get the road named after them. If it's their money going to improve the road it's similar to when people donate money to a college to get their name on a building. They are a gas station, but it's not like a kum & go where they would have multiple locations in a smaller area. Other gas stations are like Walmart- it's important that the address actually tells you it's location without having to look up which one it is, but since Buc-ees is more of an attraction for people driving by that doesn't matter. If you look up Ikea locations you'll find a large number of them are located on a street named Ikea.
