In the article on the San Francisco-Oakland Bay Bridge California Scraps Sole Bid for Signature Span, some of the information is out of date compared with a recent Bechtel report (ENR 10/11 p. 10). The cost of the bridge has increased to $5.13 billion, more than three times the original budget. This makes it the most expensive bridge in the world. The cost for the suspension part of the bridge alone is currently estimated at $2.18 billion, including the foundations.
While the replacement effort for the current bridge (built in 1936) was announced as competing with time, the [California Dept. of Transportations] current estimate for completion is 2012. Ironically, Caltrans needs 10 years (construction had started in early 2002) to complete one half of the bridge that was built in 1936 in three years and seven months.
