DEEP FOUNDATIONS • NOV/DEC 2019 • 5 93 Bi-Directional Load Test on a Production Drilled Shaft in Soil for the Kosciuszko Bridge Daniela Bastos Zellers, P.E., Matteo Ferrucci, P.E., Sherif Hanna, P.E., and Robert L. Adams, P.E. Due to deterioration and structural deficiencies of the original bridge, the New York State Department of Transportation commissioned a new 1.1 mi (1.8 km) long cable- stayed Kosciuszko Bridge in New York City. Due to interferences, drilled shafts were used in lieu of driven piles for Pier WB-13 (Phase 2). This article describes the subsurface conditions, design approach, construction methods and axial load testing for the drilled shafts supporting pier WB-13. J R E P C T A S G E & M
