October 16, 2000:
This is the Crockett side of the new bridge project where
hollow piles are being driven into the ground. These are the
foundations for the bridge towers. There are 12 piles for each
tower. In the larger picture these look like rusty pipes lying
underneath the bridge. When they are driven, they get filled with cement. Even
though it's not visible, a lot of hard work has been done and progress has
been made underwater. |

October 16, 2000:
The old bridge (closest) was built in 1927 and is not
earthquake-proof. It will not hold up much longer. After the
new bridge is completed, it will take 2 years to take the old one down
piece by piece. Some of the pieces will go to local museums for
anyone interested in bridge history. |

October 16, 2000: Before the construction began on the new
bridge, an Environmental Impact Study needed to be done to see how the the
building would affect animals and plants. In this picture, there is a
little platform that is used to build the bridge without disturbing the environment.
There is a sensitive area underneath the bridge where juvenile salmon
rest. People were also worried about other endangered animals like the Peregrine
Falcon and the red-legged frog.
This picture also shows the beginnings of what is called
"Pier One." It is the base of where the bridge and
the new Crockett interchange will meet at the edge of the water. You
can see it on the larger picture below the red crane. Pier Two will
be the base of the South Tower, one of the major structures of the bridge
where the cables will be suspended from. The picture above shows
where the South Tower will be built, at the point where the white crane is
placed now.

December 16, 2000:
We were
standing at the Visitors Center taking pictures on the Crockett side
towards the Vallejo side. This picture shows the pile driving for the
tower. The white crane is holding the pile-driver. |
 |
December 16, 2000:
We were on the
Vallejo side at The Maritime Academy. We were trying to get a good picture
of the pile driving. Here in this picture you can see the temporary bridge
that was built for the workers to get to the site of the north tower. |
 |
December 16, 2000: This is a
close-up picture of the pile driving. What you see here is the machinery
that was pile driving. |
 |
December 16, 2000: Here we are
looking at the bridge site from the Vallejo side. The noise was
tremendously head-throbbing. |
 |
March 7, 2001: This picture
shows the first structure coming out of the water. It is called pier one.
It is where the new interchange will meet the new bridge. You can see this
picture better if you click on the smaller version. The criss-cross
metal on the new pier is called falsework.
When the concrete sets the falsework will be knocked down. |
|

|
March 7, 2001: This picture
shows pier two, the south tower. Engineers were having trouble
driving the piles because the soil in the ground was too soft and it
started to cave in. To fix this problem, engineers had to have an
under reamer built in Germany. |
 |
March 7, 2001: This picture
shows the piles being driven. This is where the anchorage is going
to be built. The anchorage is where the cables will fastened into
the ground. You can see the huge hole in the center of this picture
if you enlarge it. |
