Pictures of the massive bridge over San Francisco waters   | July 24, 2013

Here is a photo gallery of the construction of the world's biggest self anchored construction bridge. It has taken quite a while since a portion of the bridge collapsed in the Pieta Loma earthquake.

See how massive the construction is.

Discovery Channel features the Bay Bridge construction

The Bay bridge replacement is scheduled to be opened for opening by September  2013.  It started constuction in 2002 after 1989 earthquake damaged a span.  It was considered unsafe due to its rigid construction.  When the earthquake struck, the bolts sheared and the spans fell.

The new bridge built at a cost of $6.3 billion  it is considered the longest self anchored suspension bolt.  It features 28 independent spans that can flex under extreme earthquake condition and has flexible joints that are interconnected.

However the bridge construction was marred by allegation of irregularities including bolt failures and superficial welds, delays etc. 

Will this bridge be safe?  Or will it fail just like the Eastern section that failed in the La Loma Prieta of Oct l7, l989 (6.9 magnitude)
