If you are taking the escalators up out of the Roosevelt Island subway station you can end up getting a rude surprise when you get to the Upper Mezzanine as Escalator 413 is out of service until November 7th. What is especially annoying about this is that if you can’t walk the remaining stairs you have to go back down two levels and walk about ½ of the platform's length to get to one the elevators. And to boot the elevator on the Manhattan platform has been finicky lately and we just got two of the lower escalators back on line. We can't catch a break at this station.
The below map details which escalator is which for reference purposes.
