Project Information
The new Interchange will add capacity and relieve current and future congestion. View the community meeting PowerPoint Presentation. Caltrans is the lead agency and is responsible for all aspects of construction management throughout the project, including traffic control and primary public communication. City staff will meet with Caltrans regularly to get construction updates and will work with the agency on ways to minimize construction disruption and share their public information updates.
The $98 million project is scheduled for completion by December 2021. Improvements include providing additional capacity, better traffic flow, enhanced safety, reduced congestion and delays. Additionally, the project will enable the future construction of the Northbound Truck Climbing Lane, between Lambert Road and the Orange County and Los Angeles County line.
