On April 23, 2020, WMATA announced that Silver Line service will be suspended beginning on May 23, 2020 in order to rebuild stations west of Ballston–MU station and to complete the second phase of the Silver Line. This was in part due to the historically low ridership numbers for the transit agency due to the ongoing COVID-19 pandemic, traffic free highways, and WMATA wanting to get around the clock maintenance done; it will be easier for work to be done without any riders or trains interfering with the workers. They offered local bus service from Wiehle, Greensboro, Spring Hill, Tysons, McLean, and East Falls Church to Ballston. Originally, WMATA planned on reducing Orange and Silver Line trains while continuously single tracking at East Falls Church instead of a full closure. Later that summer, while the Silver Line was closed, work began on integrating Phase 2's computerized control systems with those of the rest of the Metrorail system, a crucial step towards its completion. After this tie-in procedure is completed, which is expected to occur by the end of July, WMATA plans to take control of all remaining work to be done for Phase 2 and conduct a final round of testing before it is ready for service in early 2021. Phase 2's train control systems were finally integrated with that of the Metrorail system by the end of August and three more days of closures are planned to take place in November and December for final dynamic testing. On June 24, 2020, WMATA announced that Silver Line service will resume three weeks early when trains are able to bypass East Falls Church station. All Silver Line service resumed on August 16, 2020 when Silver and Orange Line trains were able to bypass East Falls Church. East Falls Church reopened on August 23, 2020.
