The second LRT line in Minnesota, the METRO Green Line (formally Center Corridor LRT) entered service on June 14, 2014. The Green Line, together with the Blue Line and the Northstar Commuter Line, provides enhanced and connected transit choices for those living in the Twin Cities area.

The line includes destination stops at the University of Minnesota and the Minnesota Capitol. Since rolling out service, the average weekday ridership has exceeded all expectations at approximately 40,000 riders daily.
