The University Line is an obsolete designation to a light rail line of Utah Transit Authority's (UTA) TRAX system in Salt Lake City. It was the second TRAX line opened by UTA, after the Sandy/Salt Lake Line opened in 1999. The original line ran from the Delta Center Station to the Stadium Station, which is west of the Rice-Eccles Stadium on the University of Utah campus. The eastern end of the line was extended to the University Medical Center Station in 2003, and the western end was extended in 2008 to the new Salt Lake City Intermodal Hub. The University Line continued running under that name through August 6, 2011, after which this designation was no longer used following a system redesign. The University of Utah is now served by the Red Line.
