As of December 15th and till today, two out of three street-level escalators at Foggy Bottom Metro station are closed. Only one narrow escalator serves double duty as up/down stairs for rush hour crowds. It’s an outrage and an unmitigated catastrophe in progress, but still nothing new to this beleaguered Metro station. This means more lines, more crowding, more walking down broken steps. Avoid it if you can: use this handy map to find alternative Metro station entrances. More on this from Dr. Gridlock.
Update: As of about 7PM, the middle escalator has been opened, but only as stairs, with escalator #3 going up. There was no backup or bottleneck; how was it for you?
