Phase 3 - Support Piers: Implosions of the last two remaining piers - E17 & E18 completed November 11, 2017

On Saturday, November 11, 2017 Caltrans completed the demolition schedule for the remaining 13 marine foundations of the original East Span of the Bay Bridge with the implosions of the last two remaining piers - E17 & E18. The series of implosions to demolish the 1936 concrete structures took place over six weekends. Caltrans has combined multiple piers on certain demolition dates, allowing the demolition work to be completed a year ahead of schedule, saving taxpayers nearly $10 million.

Project completion is projected by the end of 2017.

Demolition Overview

Demolition of the nearly 2-mile long original East Span has been taking place in three phases with crews carefully dismantling the 77-year old East Span section-by-section, in roughly the reverse order of how it was built in the mid-1930s.

  • Phase 1 - Cantilever: Crews initially worked in the westward direction, toward Yerba Buena Island, taking apart the cantilever section and demolishing the S-Curve.
    - COMPLETED: Removed June 11, 2015.
  • Phase 2 - Trusses: included moving east to dismantle the 504’ and the 288’ truss spans that stretched east of the cantilever to the Oakland shore.
    - COMPLETED: Last Truss Removed March 28, 2017.
  • Phase 3 - Support Piers: the demolition team headed to the waterline to remove the piers and pilings and then extracting the marine foundations that support the original span down to the mud line.
    - IN PROGRESS: Final implosion completed November 11, 2017 and project completion projected by the end of 2017.

When the entire demolition of the Old Bay Bridge is complete, over 58,000 tons of steel and 245,000 tons of concrete will have been removed.
