 Hi, I'm Julia Baylis with Cal OES. Unpredictable weather means road conditions and routes can change just as quickly as the weather does. When traveling, do not rely on third-party apps and navigation tools to look for shortcuts. The Caltrans Quickmap tool is the only official source for road closures, chain requirements, detours, and more. You can download the Quickmap app to have real-time traffic information in the palm of your hand or go online to quickmap.dot.ca.gov And to see more from us, go to news.caloes.ca.gov and make sure to follow us on all of our social media platforms.
