What was the name of McDonald's first drive-through restaurant, opened near Fort Huachuca in 1975?

McDonald's first drive-through restaurant opened near Fort Huachuca in Sierra Vista, Arizona, in 1975; it is commonly identified as the Sierra Vista McDonald's.

The location served military personnel who could not leave their vehicles while wearing duty uniforms. A drive-through window gave McDonald's a new service format and expanded the brand beyond the traditional indoor counter and seating model.

This innovation became closely tied to McDonald's visual and operational identity. Signs, menu boards, lane markings, and the familiar window format made the drive-through instantly recognizable in markets around the world.

The date is sometimes confused with the later explosive growth of drive-through service. McDonald's had restaurants with drive-through windows after this pioneering 1975 location, but the first one is associated with Sierra Vista, Arizona.
