The New NY Bridge (Tappan Zee Bridge Replacement)

PACOTECH™  provided cost estimations on the original alternatives study for the Tappan Zee Bridge Replacement/I-287 Corridor now known as the New NY Bridge Project. Additional services provided by PACO on the project include cost estimation, document control, quality assurance/quality control, design support, and cost-loaded scheduling.

The New NY Bridge project is creating a state-of-the-art, twin-span replacement for the 3.1-mile Tappan Zee Bridge across the Hudson River. The existing Governor Malcolm Wilson Tappan Zee Bridge opened to traffic in 1955 and is a vital artery for residents, commuters, travelers and commercial traffic. Bridge traffic has grown to about 138,000 vehicles per day, far more than the Tappan Zee was designed to support. Heavy traffic, narrow lanes and the lack of emergency shoulders have created unsafe driving conditions. As a result, the bridge has twice the average accident rate per mile as the rest of the 574-mile Thruway system. Hundreds of millions of dollars have been spent to maintain the structure in recent years. The cost of maintaining the current bridge for the foreseeable future rivaled the cost of a new bridge, with no improvements to current traffic conditions, which necessitated the New NY Bridge.
