Eastern Concrete Materials awarded New Tappan Zee Bridge
Nov, 06 2013
Eastern Concrete Materials, Inc., a business unit of U.S. Concrete, Inc. (Nasdaq:USCR), has been awarded and begun delivering the land-supplied ready-mix concrete for the three-mile long New Tappan Zee Bridge. The new bridge crosses the Hudson River at one of its widest points and will replace the deteriorating, congested, and expensive-to-maintain Governor Malcolm Wilson Tappan Zee Bridge. The existing bridge opened to traffic nearly 60 years ago and carries more than 138,000 metropolitan New York area commuters between New York'sRockland and Westchester counties every day.
In January of this year, in an innovative departure from the traditional process used to design and build roads and bridges, The New York State Thruway Authority issued a notice to proceed with the design and construction of the new eight-lane bridge to Eastern's customer, design-builder Tappan Zee Constructors (TZC). The design-build process is a streamlined approach to construction that saves time and money over the traditional design-bid-build approach.
The new bridge, constructed of low maintenance "100-year life concrete", will be the widest bridge of its length in the world and will have eight traffic lanes, a bike and pedestrian walkway, and provisions for a rail transit installation.
The TZC team, comprised of Fluor Enterprises, Inc., American Bridge Company, Granite Construction Northeast, Inc., and Traylor Bros., Inc., and their engineering consultant HDR, was selected from among a field of two other design-build teams that competed for the work.
TZC's $3.1 billion proposal for a sinuous, cable-stayed, dual-span, twin bridge was chosen not only for its low initial cost and long-term maintenance cost, but also because TZC's design and construction process posed the least disruption to the ecology of the Hudson River while satisfying other requirements for schedule, function, appearance and reduced maintenance. The bridge's landmark design has already received international acclaim for its unique and pleasingly-lit angled main-span towers.
Construction and opening of the new bridge, together with demolition of the old bridge, will proceed in phases with final completion scheduled for 2017.
