Abstract:
Describes investigation and design of repairs to the approach decks of the Verrazano Narrows Bridge in New York City. In addition, all the joints will be replaced, electric manholes and pull boxes will be rehabilitated, and new power and communications cables will be pulled. These bare concrete decks exhibit extensive deterioration in the form of spalls, cracks, leakage, and efflorescence. A total of approximately 787,000 square feet of deck area will be repaired; this includes approximately 150,000 square feet of deck replacement. Total estimated cost is $45 million, and the construction duration is 5 to 6 years.
