Union Station and the Central Platte Valley make up Denver's newest high-rise neighborhood, built largely since Union Station reopened as a regional rail and bus hub in 2014. Apartment towers line Riverfront Park and Commons Park along the South Platte River, and commuter trains to Denver International Airport leave from the station. Downtown, LoDo and LoHi are all within walking distance. DenverApartmentBuildings.com lists 15 apartment buildings in Union Station / Central Platte Valley.
