I-40 & Choctaw Road, Oklahoma Department of Transportation

EST provided pedological soil survey for the design of I-40 over Choctaw Road, the entrance and exit ramps and Choctaw Road in Oklahoma City. Conceptual plans indicated up to approximately 10 feet of cut to develop the design profile grade along Choctaw Road. Because of this amount cut, a soil investigation was conducted to identify and characterize the subgrade materials within 36 inches below the design profile grade.
