    San Francisco's New Bay Bridge Is Open For Business

    The new eastern span of the San Francisco-Oakland Bay Bridge is finally complete.

    The new eastern span of the San Francisco-Oakland Bay Bridge was completed over Labor Day weekend

    Why did we need a new span of the bridge to begin with?

    It's been 20+ years since the existing span was damaged in the 1989 Lomo Prieta earthquake

    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.

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

    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.

    This will be the largest public works project in California

    Out of 280,000 vehicles that cross the bridge daily, here is the last one to use the old bridge

    42,000 hours of construction work in four minutes
