It took me one and half hour to get to office in the morning, all because of mess on 680.
Based on the bad experience I got all the time from 680, I decided to avoid the regular route I take – Santa Rita onto 580, then 680. Instead, I will take local and then get onto 680 on Sunol, this route is quite stable, though it always takes 20 min, while with my current route, the best is 10 min, and the worst is 40 min.
