The San Francisco Bay Area is dependent on our bridges - and the Bay Bridge is possibly the most important, linking the East Bay with San Francisco, Marin and the Peninsula. Yesterday, a cable from a Labor Day weekend repair snapped, cutting a car in half, but miraculously not injuring anyone. Now, the bridge is closed and federal experts have been brought in to help troubleshoot. Bart and Caltran are fighting over who will pay for extended operation hours to allow more people to take public transport and the world as we know it is coming to an end.
