The Hiawatha Light Rail will not run between the two terminals at the Minneapolis-St. Paul International Airport from midnight Wednesday to 3:30 a.m. Thursday.
Route 55 buses will substitute for trains while crews conduct track maintenance.
Buses will follow the normal light rail schedule, but trips will take longer by bus.
Metro Transit staff will be on site to direct passengers to Route 55 bus stops.
Trains will operate as normal elsewhere on the line between the airport and downtown Minneapolis and from the airport to the Mall of America.
