The METRO Blue Line Extension will provide transit improvements in the highly traveled northwest area of the Twin Cities. The Blue Line Extension will operate northwest from downtown Minneapolis through north Minneapolis, Golden Valley, Robbinsdale, Crystal, and Brooklyn Park. The proposed alignment is primarily at-grade and is about 13 miles of double track. It will have up to 11 new stations in addition to Target Field Station. The line will connect to the METRO Blue Line and METRO Green Line, the future METRO Green Line Extension, BRT on the METRO Red Line, the Northstar commuter rail line, and local and express bus routes. Service is to begin in 2022.
