I-5/SR 56 Interchange Project

I-5-56 Interchange
Since 2000, the City of San Diego, SANDAG and Caltrans have been studying the I-5/SR 56 Interchange in an effort to improve local and regional traffic. This regional interchange connects two of San Diego’s most critical north-to-south and east-to-west freeways.

The I-5/SR 56 Interchange Project proposes to improve the traffic operations on I-5 between Del Mar Heights Road and Carmel Valley Road, and on SR 56 between I-5 and Carmel Country Road.

On May 18, 2012, the Draft Environmental Impact Report (EIR)/ Environmental Impact Statement (EIS) for the I-5/SR 56 Interchange Project was released for a 45-day public review and comment period. In response to requests by the community, Caltrans extended the public comment period until July 17. The public comment period is now closed.

The Draft EIR/EIS is a direct result of more than ten years of community, private and public collaboration.  Five alternatives (four build and one no build) are included in the Draft EIR/EIS, which analyzes environmental, air quality, visual and other community impacts. 

On June 13, 2012, Caltrans held a public meeting on the I-5/SR 56 Interchange Project at Del Mar Hills Academy, located at 14085 Mango Drive in Del Mar.  The meeting allowed community members an opportunity to provide feedback and ask project team members questions about the project. To view materials handed out or on display at the meeting, please visit the Documents page.

July 2014 Project Update

Caltrans is currently studying the project alternatives and expects to release the Final EIR/EIS this fall. At that time, the Locally Preferred Alternative will also be announced and documented in the Final EIR/EIS.
