Bay Bridge

We stopped at Yerba Buena Island on our way to Berkeley and got some great views of the San Francisco skyline.
The island serves as a resting point on the way to Oakland.
Workers are busy building a new span linking the island to Oakland that will replace the old span, which could collapse during a major earthquake.

The project will take years to complete and cost billions of dollars. The signature suspension bridge segment of the span - shown in this artist rendering - will cost $1.5 billion to build on its own.
