Metro Line: Blue

Maintenance Window: October 3, to Sunday, October 5

Track Maintenance: Metrorail customers traveling between the Stadium-Armory and Addison Road Seat Pleasant Metrorail stations should add at least 20 minutes of travel time because of floating slab replacement. Trains will share one track between these locations from 10 p.m., Friday, October 3, to closing (3 a.m.), Sunday, October 5. Floating slabs are large sections of concrete which rest on doughnut-shaped, rubber pads. The floating slabs support the railroad tracks over which the trains run and absorb vibrations and noise from trains.
