This in from Notify NYC:
Notification issued 11/7/14 at 3:00 PM. The overnight detours of Manhattan-bound traffic on the Brooklyn Bridge will be extended to include daytime hours this weekend, November 7th to November 10th. During this time, the Brooklyn Bridge will be closed to Manhattan-bound traffic from midnight on Friday night until 6:00 a.m. on Monday morning (54 consecutive hours). Among other operations, this full weekend closure will enable the contractor to place asphalt on a portion of the Manhattan-bound Brooklyn Approach. While the Manhattan Bridge remains an alternative for Manhattan-bound traffic, we urge motorists to also consider taking the Williamsburg Bridge or Brooklyn-Battery Tunnel (MTA-tolled facility) due to an expected high volume of traffic. Brooklyn-bound motorists will access the lanes of the Brooklyn Bridge normally.
