The Millennium Force Roller Coaster is the world's largest steel roller coaster. The Millennium Force
Roller Coaster is unique in many different ways. It is the first coaster to use an elevator cable system to
get it up the first hill. It uses a magnetic braking system instead of friction. At 310 feet, it is the world's
tallest coaster and, it is the world's fastest coaster at 92 miles per hour! The coaster has 226 footers,
which contain 9400 yards of concrete. The best thing about the coaster is that it takes riders up at a 45-
degree angle and they go down at an 80-degree angle - almost straight down!
