This is the latest expansion by DHL at the airport. The $10 million air shipment facility is located at O'Hare's northeast cargo campus.
The e-commerce industry is rapidly growing. DHL officials said that's why the company continues to expand.
They chose Chicago for its strong network of transportation and workforce. O'Hare is a leading international cargo airport, ranking No. 2 in the country by value of shipments.
Mayor Rahm Emanuel will be on hand for the opening of the new facility Wednesday morning.
