The eastern span replacement of the San Francisco–Oakland Bay Bridge has been under construction since 2002. Originally scheduled to open in 2007, several delays caused it to now be scheduled to open to traffic on or just after Labor Day 2013 at an estimated cost of $6.3 billion.
The Bay Bridge is comprised of two major sections, the western suspension spans and their approach structures between San Francisco and Yerba Buena Island (YBI), and various types of truss spans between YBI and the eastern terminus in Oakland.
The original spans of the bridge east of Yerba Buena Island became the subject of concern after a section collapsed during the Loma Prieta earthquake on October 17, 1989. The replacement span is engineered to withstand the largest earthquake expected over a 1500 year period, and it is expected to last at least 150 years with proper maintenance.
The Self-Anchored Suspension (SAS) tower reached structural completion in 2011 while the entire SAS span was fully built by summer 2012. Load transfer was completed on November 20, 2012, officially making the span the largest self-anchored suspension bridge in the world.
Famous quotes containing the words francisco, bay, eastern, san, replacement, span and/or bridge:
“Today, San Francisco has experienced a double tragedy of incredible proportions. As acting mayor, I order an immediate state of mourning in our city. The city and county of San Francisco must and will pull itself together at this time. We will carry on as best as we possibly can.... I think we all have to share the same sense of shame and the same sense of outrage.”
—Dianne Feinstein (b. 1933)
“Shall we now
Contaminate our fingers with base bribes,
And sell the mighty space of our large honors
For so much trash as may be grasped thus?
I had rather be a dog and bay the moon
Than such a Roman.”
—William Shakespeare (1564–1616)
“From this elevation, just on the skirts of the clouds, we could overlook the country, west and south, for a hundred miles. There it was, the State of Maine, which we had seen on the map, but not much like that,—immeasurable forest for the sun to shine on, the eastern stuff we hear of in Massachusetts. No clearing, no house. It did not look as if a solitary traveler had cut so much as a walking-stick there.”
—Henry David Thoreau (1817–1862)
“the San Marco Library,
Whence turbulent Italy should draw
Delight in Art whose end is peace,
In logic and in natural law
By sucking at the dugs of Greece.”
—William Butler Yeats (1865–1939)
“Not even the visionary or mystical experience ever lasts very long. It is for art to capture that experience, to offer it to, in the case of literature, its readers; to be, for a secular, materialist culture, some sort of replacement for what the love of god offers in the world of faith.”
—Salman Rushdie (b. 1947)
“A tree that can fill the span of a man’s arms
Grows from a downy tip;
A terrace nine stories high
Rises from hodfuls of earth;
A journey of a thousand miles
Starts from beneath one’s feet.”
—Lao-Tzu (6th century B.C.)
“Like a bridge over troubled water
I will lay me down.”
—Paul Simon (b. 1949)
