This project was aimed to alleviate traffic congestion on Newport Road by providing more through lanes over the freeway and easier freeway access. Specifically, this project provided two additional lanes for a total of six lanes of freeway overcrossing through lanes, created dedicated right-hand turn lanes in each direction for easy on-ramp access, and built two new loop ramps, which eliminated all left turns for freeway access. DHS was responsible for oversight of the entire project from pre-bid, utility relocations, throughout construction completion. This included, quantity checks, as-builts, change orders, RFI and submittal review. The schedule was critical to the project due to the heavy traffic through the project and DHS analyzed the CPM schedule and ensured the contractor hit important Project Milestones.
