Metro Red Line trains are single-tracking between the Van Ness and Dupont Circle stations after 10 p.m. Wednesday through Thursday. Riders may experience delays.

Construction to improve the ventilation in the Red Line tunnel began in July 2021. WMATA anticipates the construction to take about 2 years to complete.

The new tunnel ventilation system will blow smoke up through existing vent shafts in the event of an emergency. Powerful ventilation fans will be installed on three new platforms over the tracks, which will be located at the base of existing ventilation shafts more than 100 feet below Connecticut Ave. The new platforms will feature dampers that can be opened and closed to channel airflow into a specific tunnel in the event of an emergency. Electrical upgrades at each station will also be installed to support the new ventilation system.
