Metro Transit needs to do some construction and maintenance work on part of the light-rail system, and to do that the agency will shut down service on the Green Line and Blue lines in Minneapolis from 7 p.m. Friday until 3 a.m. Monday.

On the Blue Line, trains will not run between Franklin Avenue and Target Field. On the Green Line, trains will not run between Stadium Village at the University of Minnesota and Target Field.

Trains will run as normal elsewhere on both lines.

Buses will substitute for trains on the closed portions of the lines. While service will mirror light-rail schedules, trips by bus can take longer and riders should plan accordingly, Metro Transit said.

Here are the affected stations and where to catch replacement buses:
