Old Bay Bridge Demolition
November 5, 2013 - June 11, 2015
Phase 1 - Cantilever
Separating and Dismantling the Cantilever Truss to Yerba Buena Island
COMPLETED: Removed June 11, 2015.
The first phase of the demolition process involved cutting the cantilever section at its center and then dismantling both sides.
Before the demolition team cut through the cantilever and separated its two halves, preparations were made to reduce structural tension and pull the suspended span on each end toward the rest of the bridge. Without these precautions, the two halves would have collapsed and fallen into the water below.
Crews also demolished the temporary bypass known as the S-Curve. This section of the original span along was cleared first in order to allow contractors to complete the bicycle and pedestrian path and to construct the permanent eastbound on-ramp from Yerba Buena Island.
