The Washington Metropolitan Area Transit Authority’s (WMATA) last SafeTrack surge -- Surge #16 – will completely close the Shady Grove and Rockville Red Line stations from Saturday, June 17 through Sunday, June 25. Metro will be providing shuttle bus service from the Shady Grove and Rockville stations, but is urging commuters to avoid the stations if possible, particularly during weekday, peak travel hours and consider telecommuting, ride sharing and other alternatives. Travelers are also encouraged to consider using the Brunswick Line MARC Train from Metropolitan Grove or starting their Metrorail trip at Twinbrook, White Flint, Glenmont or Wheaton stations.Red Line trains will operate near normal service between Twinbrook and Glenmont every eight minutes (normally every six minutes). Additional Red Line trains will operate between Grosvenor and Silver Spring every four minutes (normally every three minutes). However, commuters are advised to allow additional time to travel to their destinations.Check the WMATA website for updates.
