The Metro Blue Line is a 12-mile (19.3 km) light rail line in Hennepin County, Minnesota, that is part of the Metro network. It travels from downtown Minneapolis to Minneapolis–Saint Paul International Airport and the southern suburb of Bloomington. Formerly the Hiawatha Line (Route 55) prior to May 2013, the line was originally named after the Milwaukee Road's Hiawatha passenger train and Hiawatha Avenue, reusing infrastructure from the former and running parallel to the latter for a portion of the route. The line opened June 26, 2004, and was the first light rail service in Minnesota. An extension, Bottineau LRT, is planned to open in 2028.
