The Red Line Metro stations at Rhode Island Avenue and Brookland-CUA will be closed for 45 days beginning Saturday, July 21, for structural repair work, including addressing deteriorating platform conditions that affect the ADA-accessibility of the station.

During the closing period, the Red Line will not offer service between Fort Totten and NoMa-Gallaudet U stations. Passengers can transfer to the Green or Yellow lines at Fort Totten and head to Gallery Place to avoid the work zone.

Earlier, Metro announced that it would offer additional Yellow Line service, including running trains to Greenbelt, to help accommodate travelers.

The work is needed to complete a temporary remediation done in 2016 after concrete fell from the raised structure over Rhode Island Avenue, which is the oldest outdoor station in the system.

Free shuttle busses will be available at Rhode Island and Brookland to provide service between the closed stations and Fort Totten and NoMa-Gallaudet U stations. In addition, Metro will run express shuttles to Metro Center, Gallery Place and Union Station.

There also will be a new dedicated bus lane along Rhode Island Ave., N.E. for MetroExtra G9 service from North Capitol Street to 12th St., N.E. Monday through Saturday from 7 a.m. to 7 p.m.

In addition to the closed stations discussed above, the Fort Totten and Takoma stations will be closed for switch maintenance during the July 28-29 weekend.

Normal service is expected to resume Tuesday, Sept. 4.
