With everyone so broke, this probably won't happen anytime soon, but it's still fun to think about what might ultimately go atop the sunken BQE that nastily cleaves Carroll Gardens and Red Hook if they ever put a lid on it. The mayor wants housing. (Feel like it'd be kinda tight, right?) This story says locals like congresswoman Nydia Velazquez want pretty, mini-park walkways. And some people just want more bridges for walkers and bikers, 'cause there's only four. We want a big, long, family-friendly Costco. Kidding. [Brooklyn Paper]
