Where SBX takes you

Ever imagine how much faster it would be to get to Downtown, Santee, Sorrento Valley, Otay Mesa, I-15, I-8 or La Jolla if only there was a more direct route or better connections? No need to imagine any longer! South Bay Expressway fills a gap in San Diego's highway network, providing drivers with a fast, easy route and connections to all of the places you want to go.

South Bay Expressway extends from the SR 54 in Spring Valley through eastern Chula Vista to the Otay Mesa Road/SR 905 intersection near the Otay Mesa Border Crossing. Whether you're headed to shopping, work or home, you'll find that South Bay Expressway is convenient and close by.
