I-405 Corridor Widening – Los Angeles, CA

Description

Andreas De Blue Corp successfully led the expansion of Interstate 405, one of the most heavily trafficked corridors in the United States. This transformative infrastructure project was designed to alleviate chronic congestion, enhance commuter safety, and support long-term regional mobility across Southern California. Our scope included the widening of over 16 miles of freeway, construction of new high-occupancy vehicle (HOV) lanes, and the upgrade of multiple overpasses, on-ramps, and interchanges.

Operating in a high-density urban environment required exceptional logistical planning and 24/7 operational coordination. Andreas De Blue Corp utilized phased construction schedules, advanced traffic management systems, and environmentally sensitive practices to minimize disruption to the more than 300,000 daily drivers. We also implemented real-time digital monitoring tools to track progress, ensure safety compliance, and maintain transparency with local and state transportation authorities.

Key milestones included the demolition and reconstruction of critical structures such as the Mulholland Bridge and Sunset Boulevard ramps, all completed with minimal closures and ahead of projected timelines. Our crews worked with precision to realign roadways, install modern drainage systems, and upgrade seismic resiliency across the corridor — positioning I-405 to serve the region for decades to come.

This project underscores Andreas De Blue Corp’s commitment to solving complex transportation challenges with sustainable, forward-looking solutions. By investing in smarter infrastructure today, we helped unlock economic growth, reduce emissions, and improve quality of life for millions of California commuters.
