In case it wasn’t obvious when you boarded the Metrorail system this morning, WMATA says it did indeed finish up that major rail interlocking replacement and bridge work that saw three Metro stations on the Green and Yellow lines closed for the entire three-day weekend. Also notable: Metro counted 64,228 people who took advantage of the free shuttle buses that were moving riders around the closures. That figure is just shy of the 68,000 or so who used the shuttles during the similar Labor Day weekend closures.
