Thursday morning planes began landing and taking off on the new 10,800 foot runway at O'Hare. The 1.8 billion dollar runway is expected to ease airport congestion and eliminate flight delays that have a ripple effect across the country.
Officials at Thursday morning's ribbon cutting say it's a big day for the city and passengers.
"What we have to keep in mind here is the historic importance of this project. The Department of Transportation in Washington, D.C. has made the largest federal funding commitment to any airport reconstruction project in history right here in Chicago, the hub of our national transportation network," said Senator Dick Durbin.
Aviation officials say the new runway will allow there to be nearly 90,000 more flights every year while cutting delays in half.
