4. The new bridge is the world’s longest self-anchoring suspension bridge

This design includes innovative “shear link” beams and “hinge-pipe” beams which act as shock absorbers, and will enable the bridge to withstand the largest plausible earthquake for the next 1,500 years.

5. 17,000 individual steel strands make up the suspension cables; each strand can dangle one Hummer

6. Before being built, the bridge was modeled in 4 dimensions

The bridge was modeled, simulated and analyzed in 3D and the phasing of the construction was modeled in the fourth dimension: time.

7. This will be the largest public works project in California

Costing approximately $6.4 billion and spanning 2.2 miles, the new eastern span will be making California history.
