The Roosevelt Island Operating Corp ( RIOC ) adds:

We have been advised by the Department of Transportation that there will be overnight testing of the Roosevelt Island Bridge scheduled from 12:01 a.m. Monday, July 30, 2012 to 5:00 a.m. Wednesday, August 1, 2012.

Please be advised that each test opening will take approximately 30 minutes to be completed. The test openings will be appropriately spaced to prevent the least amount of disturbance to vehicular and pedestrian traffic traversing the bridge. During this testing NYPD, NYFD and EMS units will be available to Roosevelt Island residents and visitors by dialing 911.

Sincerely,

Roosevelt Island Operating Corp Advisories Group
