To help people get around the closures, the Yellow Line will be rerouted and will follow the Blue Line route between the Pentagon and Stadium-Armory Metrorail stations with a stop at the L'Enfant Plaza Metrorail station on the lower level. Shuttle buses also will be available. 



During Columbus Day weekend, Metro will replace the entire rail interlocking (four switches) at the L'Enfant Plaza Metrorail station on the Green and Yellow lines, and will close the Yellow Line Bridge over the Potomac River to conduct an annual safety inspection and conduct track maintenance. This means there will be no Yellow Line service between the Archives-Navy Memorial-Penn Quarter and Fort Totten Metrorail stations.
