Denver Union Station is the main railway station and central transportation hub in Denver, Colorado. It is located at 17th and Wynkoop Streets in the present-day LoDo district and includes the historic terminal building, a train shed canopy, a 22-gate underground bus facility, and light rail station. The building first opened on June 1, 1881 with its present-day structure completed in 1914. In 2012, it underwent a major renovation in order to redevelop it as the centerpiece of a new transit-oriented mixed use development on the site's former rail-yards.
