I-5/SR 56 Interchange Project

This project will provide a better, less-congested freeway connection between I-5 and SR 56. It would do this by reducing congestion associated with traveling between I-5 and SR 56. This project would help to improve travel times and address congestion on I-5, SR 56, and local arterials such as El Camino Real, caused by traffic going from Westbound SR 56 to Northbound I-5 or Southbound I-5 to Eastbound SR 56.

Preliminary design work has begun and includes:

• A traffic study was completed which includes traffic counts and volume forecasts for the year 2030.
• A bike path feasibility study was completed in 2007 to review the possibility of extending the SR 56 bike path west of I-5.
• Preliminary planning of the highway configuration
• Community Workshops & Community Planning Group Presentations

Funding

Project funding for the Project Report (PR) and Environmental Document (ED) will be taken from a combination of Federal sources and City of San Diego funds. Federal Funding sources include Coordinated Borders Infrastructure (CBI), Federal High Priority Demonstration (DEMO), and Surface Transportation funds. Approximately $9.5 million has been programmed for the I-5/SR-56 Interchange Project. Design and construction for the project would be dependent on completion of the PR/ED phase.

Schedule

A Draft Environmental Document is expected to be available for public review in fall 2010. The Project Report/Environmental Document phase will build on the previous studies while exploring new solutions. A Value Analysis Report was completed in May 2002. This study involved community representatives and agency staff from the city of San Diego, Caltrans, and the San Diego Association of Governments. A Project Study Report was completed by Caltrans in December 2000. That document discussed a Freeway Connectors alternative, a Local Streets alternative, and the No Build alternative.

Auxiliary Lane Alternative

Project Description Includes widening of the city street and the freeway. This alternative would not construct either the Westbound to Northbound or the Southbound to Eastbound Connector. West of I-5, new retaining walls would be constructed on the existing slopes, but impacts would be east of the existing sound walls.

Direct Connector Alternative

Project Description This alternative would require the realignment of Portofino Circle. To the North of Portofino Circle, new retaining walls are anticipated in the area of the existing sound walls. This alternative would require easements and would have right of way impacts, but would not require acquisition of residences.

Hybrid Connector Alternative

Project Description Construct the Westbound to Northbound connector and the Auxiliary Lane Alternative components in the south to east direction. Please note: while studies are required for both Westbound/Northbound and Southbound/Eastbound connectors, if the cost and impacts of one significantly outweighs its benefits, that factor can cause only one to be constructed.

Modified Hybrid Connector Alternative

Project Description The Hybrid with Flyover Alternative is a variation of the Hybrid Alternative. This alternative includes a proposed flyover structure that would connect eastbound Carmel Valley Road to the eastbound SR-56 fast lane, in addition to the westbound SR-56 to northbound I-5 connector featured in the Direct Connector Alternative. The Hybrid with Flyover Alternative would require use of non-standard lane and shoulder widths along Carmel Valley Road and would require tunneling behind the Carmel Valley Road undercrossing abutments to provide pedestrian/bicycle access. The Hybrid with Flyover Alternative would provide operational improvements in the westbound and northbound directions and would provide slight operational improvements over the Hybrid Alternative in the southbound and eastbound directions.

No Build Alternative

Project Description The no build option contains no new construction and/or measures to mitigate changes in traffic conditions.
