I have mixed feelings about skywalks. On the one hand, they can enhance safety for pedestrians. On the other, skywalks often smell bad and take up more time than crossing at street level. Getting to the skywalk at the Wheaton, Maryland metro station requires going up two forlorn flights of stairs. (There is also the option of taking a poorly ventilated elevator). I hope that safer street-level pedestrian crossings are taken into consideration when this area of Wheaton gets redeveloped in the coming years.
