Scope of Work:
This $55 million project for the New York State Department of Transportation entails the staged reconstruction of the Long Island Expressway over the Grand Central Parkway, mainline and service roads. In its existing condition, gaps exist between the eastbound and westbound structures. This project will fill in these gaps, thereby integrating the travel ways into a unified structure. This construction includes the installation of new 14” cast-in-place pipe piles and foundations. The existing superstructure will be completely demolished and replaced; the substructure will be demolished and replaced down to the top of footing. New pier caps will be installed on the existing piers.
The project also includes rehabilitation of the Long Island Expressway over the College Point Boulevard Bridge. This work will include deck rehabilitation, partial and full deck repairs, joint repairs, barrier repairs and overlay.
The project area is located in one of New York State’s highest volume traffic corridors, with the LIE having an AADT of 151,000 and the Grand Central Parkway having an AADT of 189,000 at the project interchange location. ECCO III will minimize traffic impacts over a 7-stage construction sequence, with the project reaching final completion in October 2018.
