The project proposes one No Build Alternative and two Build Alternatives.

Build Alternative 2 that proposed a southbound I-5 flyover to serve El Toro East and West was previously considered and eliminated due to non-compliance with State policy.

No Build Alternative

The No Build Alternative proposes no action, where no construction or improvements would be made to the I-5/El Toro Road Interchange.

Build Alternative 1

Build Alternative 1 proposes to replace the existing southbound I-5 on- and off-ramps with a braided ramp along Avenida De La Carlota. an This would include new ramp alignments, a new bridge of El Toro Road, and realignment of Avenida De La Carlota. The existing southbound direct on-ramp from El Toro Road is eliminated, while the existing access provided by the southbound ramps, opposite Paseo De La Valencia, are maintained.

Build Alternative 3

OCTA and Caltrans is evaluating a standalone Transportation Systems Management (TSM)/Transportation Demand Management (TDM) Alternative. Build Alternative 3 would install intelligent transportation systems to improve traffic signal synchronization and incorporate other transportation system management elements.
