New York City Department Of Transportation via Community Board 6.
The Third Street Bride in Gowanus will be closed intermittently in each direction on Tuesday, February 2nd from 9 am to 4 pm for needed post-Sandy repair work.
Delays may result, so you may want to avoid the area during those hours. Use the Carroll Street Bridge or the 9th Street Bridge if you can. And, of course, allow extra time if you need to cross the canal on Tuesday.
