237 & 880 Interchange

As the project manager, Darius directed geotechnical, geologic hazard, and environmental investigations for this Caltrans improvement project. The project consisted of a new direct connector structure, a braided on-ramp structure, approach embankments and roadways for the above structures, retaining walls to support approach embankments where required, southbound 880 off-ramp to westbound Tasman Drive, and widening the outside lane of southbound 880. The project includes design for flexible pavements for the new roadways and widening sections.
