The space underneath the Fourth Avenue Subway Bridge has never been that scary or disgusting: no trolls dwell in the space, nor do people hang out much and drink and do private things. Construction slows the movement of traffic, but when it’s over, the bridge will be a deco gem, like it was in 1930.
Progress under the El, too!
