2004 Roger H. Corbetta Award for Special Merit, Concrete Industry Board
FOR THE INTERCHANGE 8 RECONSTRUCTION
As part of a joint effort, the Structural Engineer Team for the Interchange 8 Reconstruction received a 2004 Award of Merit from The Concrete Industry Board. Generally considered to be the largest and most complicated reconstruction project in the history of the New York State Thruway, the Interchange 8 project was undertaken to enhance mobility and improve safety for the large number of motorists who travel along the Tappan Zee Bridge corridor daily.
HIGHLIGHTS
Both cast-in-place and precast concrete were used.
Precast was used for highway panels, bridges, barriers, drainage inlets and manholes, noise barrier walls, retaining walls, and concrete piping.
Cast-in-place was used for bridge footings, signs and equipment, bridge decks, highway pavement, curbs, and barriers.
To accommodate both traffic flow and the achievement of rapid strength where necessary, placement sometimes involved volumes of over 1,000 cubic yards and extended shifts of up to 16 hours.
Nearly 2,500 cylinders were tested to assure quality during this 36-month project.
