It is a bypass auxiliary route of I-5, running roughly through the center of the Greater San Diego region from San Ysidro (part of the city of San Diego) near the Mexico–U.S. border to near Del Mar.

However, this would have added $10 million (equivalent to $ in ) to the cost of the freeway, and possibly delay it by up to 10 years; furthermore, most traffic crossing the border was found to head to Tijuana and not Ensenada.
