More money has been approved to redo Chicago's Circle Interchange.
Gov. Pat Quinn announced Thursday that he has released $42.5 million for the ongoing project. The total cost of the four-year project is $475 million. The latest money will pay for a bridge at Halsted and Harrison streets and new approaches. The Circle Interchange is where several major expressways come together just west of the Chicago Loop.
The Illinois Department of Transportation is managing the Circle Interchange project.
Transportation experts say the improvements will reduce traffic delays by half.
