A section of the Hiawatha light rail line will close this weekend for construction.
Stops between 46th Street and the Mall of America stations will be closed from 11 p.m. Friday until 3:30 a.m. Monday.
Route 55 buses will operate more frequently over the weekend to replace the light rail route, but bus trips will take longer than train rides. Metro Transit staff will be at several rail stations to direct riders to buses.
Construction crews are lengthening rail platforms at stations to accommodate three-car trains. In addition, crews are working at rail and roadway intersections to upgrade the signaling system.
Trains will operate normally elsewhere along the Hiawatha Line.
