Sprint is hosting a small group of reporters from five different publications this week for a few days of meetings, tours and insights into the inner workings of the nation’s No. 3 carrier. While we’re learning plenty about Sprint’s operations — some of which we can share over the next few days and some of which we cannot — we were also given a great walking tour of part of Sprint’s massive Midwest headquarters. The carrier is situated on a gigantic campus in Overland Park, Kansas that counts among its attractions 21 office and service buildings that contain 4 million square feet of office space, 6,000 trees, 42.45 acres of prairie grass, 7.2 acres of lakes, a 3,000-seat amphitheater and 3,300 combined miles of copper and fiber cable. Though it houses the No. 85 company on the Forbes 100 and is large enough for its own zip code, the sprawling campus definitely has the look and feel of a university; red brick buildings are spread about lush lawns, four major fountains and more than a mile of walking trails. This seemingly academic spread houses some fantastically intriguing facilities, however, and we’ll get into that a bit later. In the meantime, a gallery of Sprint’s campus grounds and one of its main buildings can be seen below.
