San Francisco Chronicle/John Widermuth, 8/15/13. "New east span of Bay Bridge to open September 3rd."

| Bay Bridge East Span will be closed 6 days Closed Wednesday, 8/28/13, 8 PM Reopened Tuesday, 9/03/13, 5 AM |
.... The move came just days after federal officials gave their approval
for a temporary plan to shore up the snapped high-strength steel rods
that hold seismic stability structures together. Three independent
authorities also found that the fix is more than adequate to allow
traffic to move onto the new bridge while the permanent retrofit is
completed, which is expected to be done by December. "We see no reason to delay the opening of the bridge to traffic," said Vincent Mammano of the Federal Highway Administration." Read article.

Labor Day weekend as originally planned."

The authorities were shocked when they opened the bids on the proposed tower portion, as there was only a single bid and it was considerably more expensive (US$1.4 billion) than their estimate ($780 million), partially because of a rise in the cost of steel and concrete. As both concrete and structural steel are now commodities within the worldwide market, the prices were much higher than expected because of a concurrent building boom throughout China. (China was then consuming 40 percent of worldwide cement production.[23]) Another qualified potential bidder did not bid due to construction uncertainties owing to the innovative design—another likely contribution to the very high bid. The entire project, which will require 100,000 tons of structural steel, is now expected to cost $6.2 billion (as of July 2005), up from a 1997 estimate of $1.1 billion (for a simple viaduct) and a March 2003 estimate of $2.6 billion that included a tower span.
