The "Eternal Flame of Hope" symbolizes the Special Olympics' theme of inclusion and unity, as well as hope, says world-renowned sculpture Richard Hunt, a Chicago native.
Hunt has more than 125 pieces of sculptures on display in Chicago and across the country.
The sculpture weighs about 7,000 pounds and will have a flame that can grow to 15 feet.
The official lighting of the sculpture will be held at noon Friday after a law enforcement torch run.
This week features multiple events to honor the 50th anniversary, which will culminate with a concert featuring Chicagoan Chance the Rapper, along with several other musicians.
