Crews installed the world's largest cable saddle on top of the tower of the world's longest self-anchored suspension span. The 450-ton saddle will support the nearly one mile of cable that will hold up the eastern span's lanes.
Work began at 5 a.m.
"The challenges are always the wind because if the wind starts pushing on it, it's difficult to handle always keeping up with the machinery, but we've got people in place for that so we think we're going to have success," said Caltrans spokesperson Bart Ney.
The work is so intricate and dangerous that crews held a rehearsal on dry land last month.
The new eastern span of the bridge is scheduled to open in 2013.
