As far as timeline this is the deal (approx dates):
Jan 15th until 4-6 months later - both overpasses that go over the banks area will be covered and painted (pretty much entire banks area from Pearl to Rose streets will
be closed and off limits)
Once overpasses are painted(approx summer 2010)- the north ramp(ramp furthest away from the bridge itself) will
be uncovered and the area that is not used for staging will be open.
2014 - entire banks area will be open again.
This is the official statement from DOT:
The Brooklyn Bridge is in urgent need of rehabilitation, and this project is slated to begin in 2010 and expected to finish in 2014. During this time, a portion of the Brooklyn Banks will be closed for use by the contractor. When the storage area is established, more than half of the area currently used as a skatepark will be available for public use.
The scope of work for this project also includes painting, which is expected to begin in the winter of 2010. During painting work, the park will be closed to provide the space required for painting operations. After the painting work in this area is complete, anticipated for mid 2010, the park will be reopened with the exception of the storage area. The park will completely reopen when the rehabilitation is completed. DOT has been working closely with Steve
Rodriguez, spokesperson for the Brooklyn Banks and the communities that use it, to share this space without compromising the vital reconstruction of the Brooklyn Bridge.
Some revised timeline info (as of 03.27.2010):
The New York City Department of Transportation is performing rehabilitation and painting of the Brooklyn Bridge. Work commenced in January of 2010 and will continue until 2014. In order to facilitate the reconstruction and associated painting work, the contractor will begin to mobilize in the area between Pearl Street and Park Row on the north side of the Manhattan approach of the Brooklyn Bridge, as shown in the area below, on Wednesday March 31, 2010
The contractor will install protective guards around the trees on Wednesday, March 31st, and begin placing a concrete barrier along the perimeter of the shaded section on Friday, April 2nd. Fencing will be installed after the concrete barriers are in place, and setting up this staging area is expected to continue until approximately April 16th. DOT is continuing to work with the communities using this area, to maintain as much access as can be safely accommodated. During a 4-6 month period beginning in mid-2010, the entire area will be closed due to overhead paint work; however, DOT expects to re-instate access after this work is completed.(Read More)
