From Metro’s press release:

One month from today, following Major League Baseball’s All-Star Week, Metro will close two stations on the Red Line – Rhode Island Ave and Brookland – to complete structural repairs at Rhode Island Ave, Metro’s oldest outdoor station. The work will begin Saturday, July 21, and continue through Labor Day, Monday, September 3. The structural work cannot be completed while trains are running on either track and will resolve platform conditions that affect the alignment between the platform and trains, presenting challenges for customers with disabilities.

Metro and the District Department of Transportation have worked together to develop a comprehensive alternate transportation plan that includes operating MetroExtra G9 service during all hours of the rail system, seven days a week, and using a dedicated bus lane along Rhode Island Avenue NE to provide a faster trip to and from Downtown DC.

Red Line customers are advised:

• Rhode Island Avenue and Brookland stations will be closed for 45 days, from July 21 through September 3.
• There will be no Red Line service between Fort Totten and NoMa-Gallaudet U stations. Red Line customers should transfer to Green or Yellow line trains between Fort Totten and Gallery Place to avoid the work zone. Metro will add capacity to the Green/Yellow lines to accommodate Red Line riders, including running some Yellow Line trains to/from Greenbelt. During rush hours, Red Line trains will operate every 6 minutes between Shady Grove and NoMa-Gallaudet, and every 10 minutes between Glenmont and Fort Totten.
• For customers traveling to/from Brookland or Rhode Island Ave stations, free shuttle buses will provide alternate service between Fort Totten, Brookland, Rhode Island Ave, and NoMa-Gallaudet U stations. In addition, Metro will operate express shuttles between Brookland and Rhode Island Ave and the areas of Metro Center, Gallery Place and Union Station.
• MetroExtra G9 will operate at all hours the rail system is open, seven days per week, connecting Rhode Island Ave with Downtown DC and other rail and bus lines.
• To reduce travel times, Metro has received approval from the District Department of Transportation to use a new dedicated bus lane along Rhode Island Ave. NE for MetroExtra G9 from North Capitol St. to 12th St. NE. The lane will operate Monday through Saturday from 7 a.m. to 7 p.m.
• Rush Hour Promise will not be in effect for trips to or from stations between Glenmont and NoMa-Gallaudet U. The program will remain in effect for Red Line travel between Shady Grove and NoMa-Gallaudet U.
