Driving from San Diego to San Francisco - in One Day
Distance: 500 milesDriving Time: 8.5 hours in good traffic
Southern California freeways offer so many choices for getting from San Diego through Los Angeles and headed toward San Francisco that it could take you as long to plot your route as it would to drive it. We've made this trip many times and can help you pare down the options to just a couple.
If you're trying to make this long trip in a single day, you need to get through LA as quickly as you can. Most online mapping sites will route you through Los Angeles on I-5, but in our experience, that freeway can be more than frustratingly jammed up, adding over an hour to your trip, even when it isn't rush hour.
Instead, take I-15 north from San Diego, then I-210 west to connect to I-5 north, avoiding the busiest areas. Traffic jams can happen any time on any road, so it's best to check the current traffic situation before you set out to be sure it's the optimum route at that time. If you don't have a mobile device that provides traffic info, Los Angeles radio station KNX 1070 has frequent traffic updates.
After you connect with I-5, you'll drive north on it for about 280 miles, then take I-580 and I-80 west to San Francisco, crossing the San Francisco Bay Bridge (which charges a toll).
