For the last two years or so, Ammann & Whitney staff have been on site at the Verrazano‐Narrows Bridge overseeing a project for MTA Bridges and Tunnels, the $24M project that involves the painting and miscellaneous structural repairs to the main towers from the roadway level down to their bases.  Our team’s efforts have not gone unnoticed, and the agency has just designated Ammann & Whitney as the Construction  Management  and  Inspection  firm  for  a  New  Bus/HOV  Ramp  to connect the Gowanus Expressway in Brooklyn to the Upper Level of the Verrazano‐ Narrows Bridge (Project VN‐80C). Construction cost is estimated to be over $70M with CM fees in the neighborhood of $5.7M. 

Ammann & Whitney was the original designer of the errazano‐Narrows Bridge which, when opened to traffic in November of 1964, was the longest suspension bridge in the world. Ammann & Whitney has been involved in many projects on the bridge in the years since it opened, but this may be the largest and most significant since the original construction. 

The project will involve the construction of a new ramp which will weave its way through the spaghetti pile formed by the existing and complex ramp network forming the Brooklyn Approaches to the bridge. This will involve removal of existing structures; modification to others, including reducing depths to provide increased vertical  clearance; construction of new piers founded on micro‐piles within the congested site under the bridge; erosion, sediment, noise and dust control; and appurtenant work which will include drainage, sign structures, fire protection and lighting installation. And perhaps the greatest challenge‐ maintaining traffic during the 6 stages of construction and throughout the 3+ year construction program.
