Here’s an interesting question from one of our readers about some activity on Seventh Avenue: “For the past couple weeks construction crews have been busy tearing up the street on 7th Ave between Sterling and Flatbush. It’s been incredibly noisy and has been seriously disrupting traffic- I saw two city busses almost get into a head-on collision yesterday trying to maneuver around all the heavy machinery. Any idea what’s going on over there?”–GL Inbox
