Introduction The Interstate 5 (I-5) corridor in North County is one of the most frequently traveled freeways in San Diego County. I-5 has many unique features including six lagoons, world-renowned coastal cities and unparalleled beaches. By the year 2030, the number of vehicles using I-5 daily is expected to nearly double. To help improve the quality of life and address the increasing number of motorists on I-5, the California Department of Transportation (Caltrans) and the San Diego Association of Governments (SANDAG) are proposing a number of projects intended to reduce congestion. In this web site you will find information about the proposed projects. These projects included a long-term project to add two managed lanes in each direction. Recently completed and/or near-term projects include: I-5 HOV/ Lomas Santa Fe Project, I-805 Carroll Canyon Road Extension Project and the I-5/SR 56 Interchange Project. The information is updated frequently, so please check back. For the most recent developments in both planning and implementation of improvements to the I-5 see the section that follows.
