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.

wpe1.jpg (4765 bytes) 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.
wpe5.jpg (5359 bytes) December 16, 2000:   This is a close-up picture of the pile driving. What you see here is the machinery that was pile driving.
wpe3.jpg (6810 bytes) December 16, 2000:   Here we are looking at the bridge site from the Vallejo side. The noise was tremendously head-throbbing.
wpe1.jpg (57325 bytes) 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. 
wpe5.jpg (20947 bytes) 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.
