I-805/Mira Mesa Boulevard and Sorrento Valley Road
Interchange Project Study Report
San Diego, CA

The interchange Project Study Report was one of the key elements in landing the San Diego Association of Governments (SANDAG) and Caltrans District 11 $400 million of CMIA funding which will be used for the design and construction portions of this report's recommendations. The report also served as support for an Access Approval Request to the FHWA for a new access point to I-805 from Carroll Canyon Road.

The project included traffic forecasting, traffic impact analysis, and alternative studies to upgrade capacity of current and future area growth. The scope of work included preliminary design for upgrading of the existing interchange. The project also included alternative studies to integrate multi-modal transit components to the area, including High Occupancy Vehicle Direct Access Ramps at Carroll Canyon Road, a Bus Rapid Transit Center, and relocation of a Coaster station. Extensive coordination was required between the client, the City of San Diego, the California Department of Transportation, North County Transit District, and Metropolitan Transit System, as well as utility companies and other design consultants.
