Golden State Game-Changer: OCTA’s I-405 Express Lanes Transforms Congestion Relief

The I-405 Improvement Project by the Orange County Transportation Authority (OCTA) is a landmark initiative that introduced the 405 Express Lanes along a 16-mile stretch of one of California’s busiest freeways. This $2.2 billion project, the largest highway construction in the state, successfully alleviated congestion by implementing congestion management pricing, which adjusts toll rates hourly based on real-time traffic conditions. This innovation led to a significant reduction in travel times—42% northbound and 35% southbound. OCTA also secured a $629 million TIFIA loan, saving taxpayers over $500 million. The project reimagined the corridor by reconstructing 18 bridges, adding bike lanes, and enhancing sidewalks, promoting safer, more sustainable travel. OCTA’s effective public outreach minimized disruptions and fostered community support, making the I-405 Improvement Project a deserving recipient of IBTTA's 2024 Toll Excellence Award.
