Metro put a shiny new escalator into service today at the Bethesda station and released a (surprisingly dramatic) video to go with it.

It is the first of three escalators to be replaced at the station, a project that is slated to be finished in the spring of 2017. Metro estimates that putting in the three new 106-foot-long escalators will cost $8.4 million.

Unlike other stations where escalator banks have been replaced, there is only one entrance at the Bethesda stop. So engineers have to replace one at a time—leaving two in operation for passengers—rather than installing them all at once.

But when one of the remaining pair breaks down, they have to shut the whole station down out of a safety precaution—as happened on two occasions last month. Nearly 11,000 passengers use the station on the average weekday.

While a brand new escalator should presumably make that less likely, no one seems to be holding their breath.

@unsuckdcmetro Best feature? Pause the video to see how the new Bethesda escalator will operate within 90 days.

@loriara I know WaPo has pre-written obits for celebs who are about to die. Are you doing the same for new Bethesda escalator? #wmata

@unsuckdcmetro New escalator opens at Bethesda tomorrow morning, what’s the over/under for it breaking down?

The middle escalator is now closed for the next phase of the replacement project.
