Edmonton Transit System's light rail system runs beneath the downtown core, with one station at Churchill Square (Churchill LRT Station), three stations along Jasper Avenue (Central, Bay/Enterprise Square, and Corona) and one station at government centre (Grandin). From Grandin station, the LRT continues south over the North Saskatchewan River to three University of Alberta stations (University, Health Sciences, and South Campus), as a part of the South extension. From Churchill Station, the LRT travels north east towards Commonwealth Stadium and Northlands Coliseum. A second LRT line, connecting to MacEwan University, Royal Alexandra Hospital, Kingsway Mall, and the Northern Alberta Institute of Technology (NAIT), opened in 2015. A third line under construction, the Valley Line, will connect downtown to Mill Woods.
