Service (NCS) located at the northeast corner of the MMF; however, the NCS currently operates an occasional schedule on weekdays only. The CTA Blue Line's north terminus is at and provides direct service to downtown via the Milwaukee–Dearborn subway in the Loop and continuing to west suburban Forest Park. Trains depart at intervals ranging from every four to thirty minutes, 24 hours a day. The station is located on the lower level of the parking garage, and can be accessed directly from Terminals1–3 via tunnel and from Terminal5 via shuttle bus. O'Hare is directly served by Interstate 190, which offers interchanges with Mannheim Road (U.S. 12 and 45), the Tri-State Tollway (Interstate 294), and Interstate 90. I-90 continues as the Kennedy Expressway into downtown Chicago and becomes the Jane Addams Memorial Tollway northwest to Rockford and the Wisconsin state line. Cargo facilities There are presently two main cargo areas at O'Hare. The South Cargo Area was relocated in the 1980s from the airport's first air cargo facilities, located east of the terminal core, where Terminal5 now stands. Many of the structures in this new cargo area then had to be rebuilt, again, to allow for the OMP and specifically runway 10R/28L; as a result, what is now called the South Cargo Area is located between 10R/28L and 10C/28C. This large collection of facilities, in three sections (Southwest, South Central, and Southeast), was established mainly by traditional airline-based air cargo; Air France Cargo, American, JAL Cargo, KLM, Lufthansa Cargo, Northwest and United all built purpose-built, freestanding cargo facilities, although some of these are now leased out to dedicated cargo firms. In addition, the area contains two separate facilities for shipper FedEx and one for UPS. The Northeast Cargo Area (NEC) is a conversion of the former military base (the Douglas plant area) at the northeast corner of the airport property. It is a new facility designed to increase O'Hare's cargo capacity by 50%. Two buildings currently make up the NEC: a building completed in 2016, and a building that was completed in 2017. A third structure will complete the NEC with another of warehouse space. The current capability of the cargo areas provide of airside cargo space with parking for 40 wide-body freighters matched with over of landside warehousing capability. O'Hare shipped over in 2018, fifth among airports in the U.S. Other facilities In 2011, O'Hare became the first major airport
