Building for automobile assembly. The VAB is the world's biggest single-story skyscraper, the highest building (160.3 meters, 526 feet) in Florida until 1974, and the tallest building in the United States outside of an urban region. It is also one of the largest manufacturing facilities in the world. The building is 844 feet long (260 m), 75 feet wide (23 m), and has 49 floors. Its volume is 2,520,000 square feet (20,900 m²). It is located in Lake Worth, near the intersection of Military Trail and South Dixie Highway. Construction on the plant began in 1959 and was completed in 1964. General Motors owned and operated the plant until its closure in 2001 when it was bought by Toyoda Motor Sales USA Inc. The last car to be assembled at the facility was a 2002 Saturn SC2. The building is now used for production purposes by Toyota Motor Manufacturing USA.
