According to the Mayor’s Office press release, these will be the effects on traffic:
The majority of the work on the Brooklyn Bridge will be performed at night, requiring nighttime lane closures on the bridge’s Manhattan-bound lanes. However, for approximately 24 weekends, full closures of the span’s Manhattan-bound lanes will be required throughout the weekend beginning at 12:01 AM on Saturday night [sic; we presume this means Saturday morning] and re-opening at 5:00 AM on Monday. Brooklyn-bound traffic will be maintained during these nights and weekend closures. Traffic is expected to use the Manhattan and Williamsburg Bridges for alternate access to Manhattan, with some traffic moving to the Brooklyn Battery Tunnel. There will be no weekend closures during special events or during the holiday construction embargo. A schedule will be posted as the dates are determined.
At no time will the pedestrian and bike pathway be closed.
As for repainting the bridge, you may recall our suggestion that a color other than the present dull tan be considered. City officials have said they intend to repaint it in its original color, but, according to The Brooklyn Paper, nobody knows what that color was.
