The new eastern span of the San Francisco-Oakland Bay bridge stands next to the old bridge in San Francisco, California

The new eastern span (L) of the San Francisco-Oakland Bay bridge stands next to the old bridge in San Francisco, California September 2, 2013. The largest self-anchored suspension bridge in the world will open before Tuesday morning's rush hour across San Francisco Bay, six years behind schedule and five times over budget. The new $6 billion eastern section of the San Francisco-Oakland Bay Bridge, one of the busiest spans in the United States, is expected to be open on Tuesday for 280,000 daily commuters. The Bay Area Toll Authority said the bridge could open as soon as Monday night. REUTERS/Stephen Lam (UNITED STATES - Tags: TRANSPORT BUSINESS CONSTRUCTION)
