The I-580 freeway collapse in Oakland totally takes out a freeway that might get routed in your GPS Navigation device. This should not be a problem for the people who get traffic updates downloaded to your gps navigation systems, but for the people who don’t there is still a fix around this.
Most Garmin, Magellan and other products on the market today have navigation routing features that allows you to choose custom road preferences which allow you to prioritize the choice of back roads or major highways, simply make I-580 a low priority and this should solve the problem. Some gps devices also have a detour function that enables routing around traffic problems or road construction, using this feature could also help solve the problem.
