Repairing New York's Historic Bridges

Abstract:

The Brooklyn and Manhattan bridges are just two of New York City's venerable structures that are undergoing rehabilitation. Current work on the Brooklyn involves enlarging the anchorage pits so that the splayed cable ends may be opened up for inspection and repair. Temporary ropes have also been clamped to some of the stay (diagonal) cables to prevent breakage before all suspender and stay cables are replaced in 1986. The Manhattan bridge has always twisted when subway trains crossed it; current work will strengthen it by creating two torque tubes of the upper roadways. A state-of-the-art maintenance platform has been designed.
