The tower you see is part of the new eastern span of the Bay Bridge. The erector set behind it is the original span which will be in use until September. The new structure will be the world's largest self-anchored suspension span. It will no longer have two decks and it will also include bicycle lanes. It's only been in the works since the big earthquake of 1989 and is the most expensive public works project in California history. The span runs from Oakland to Yerba Buena Island; the western suspension section runs from the island to San Francisco. This picture was taken from Treasure Island (built on soil dredged from the construction of the original bridge which opened in 1936) looking east to Oakland. The sky shows you the weather has been clear and dry. Linked to Skywatch Friday and Weekend Reflections.
