What is the best route to Los Angeles from San Diego with light to normal traffic
Taking I-5 south have a straighter route to Los Angeles but it's usually congested with traffic. Taking the 710 south to the 405 get's you much faster with less traffic.
But traffic is unpredictable sometimes you have to check the traffic reports around those area if you should decide to take any of those routes.
