The Green Line marks one year of service on Sunday, but riders won't be celebrating so much with a portion of the line closed for track maintenance all weekend.
Green Line trains will not run between Target Field and the University of Minnesota's Stadium Village station from 7 p.m. Friday until 5 a.m. Monday.
The Blue Line won't have service between Target Field and Franklin Avenue in Minneapolis.
Trains will run as normal elsewhere on both lines. Buses will substitute for trains where the lines are down. They will run a similar schedule as trains but may take more time, Metro Transit said.
For motorists, the weekend brings a few new detours to go with long-running projects.
Here is where you will find cones and barriers:
• Friday morning, commuters will find crews repaving 9th Street between Chicago and Marquette avenues, beginning at 6 a.m. The work is scheduled to last until Saturday evening. Traffic will be diverted to 7th Street. Westbound I-94 drivers could try the 11th Street ramp to avoid tangles around the Vikings' stadium.
• The southbound lanes of the Lafayette Bridge will be closed from 4 a.m. to 2 p.m. Saturday. Traffic will be detoured east on I-94, south on Hwy. 61 and west on I-494 back to Hwy. 52. Northbound lanes will remain open.
