Additional Work
WMATA also rebuilt an interlocking switch area between Fort Totten and Takoma before that stretch of track reopened in late June.
Crews were able to complete the equivalent of eight months of weekend closures and disruptions into the summer construction period.
Later this year, WMATA will install new digital passenger information displays on platforms and station entrance digital screens at all five stations. Supply chain issues held up installation during the construction window.
