-- This Metro escalator in Bethesda, Maryland is not for the faint of heart:
The longest escalator is in the system's Wheaton Station, according to the WMATA.
The ride down in Bethesda is just under three minutes.
“This is a significant improvement for our customers at Bethesda Station,” Metro said in a statement. “This first new entrance escalator will provide more reliable service for the thousands of passengers who travel through the station each day.”
The station -- which services nearly 11,000 commuters each weekday, according to WMATA -- is undergoing a multi-million dollar renovation, which includes the new escalators and improvements to lighting.
