In addition to What this means is of displacement monitoring, a licensed land surveyor was also deployed on a close-by hillside to watch structure area previous to, for the duration of, and following the jacking functions to be able to detect any unplanned entry motion. Locking collars ended up put on the jacks as a method of offering redundancy within the event of the hydraulic failure of the jacking method. Personnel monitored the prevailing tower bearings and noted on their position by way of radio carry off.

The maximum credible earthquake is predicted to create as much as 12-inch displacements on the truss. To forestall the truss from crushing against the Marin (north) Abutment and Pylon N2, seismic enlargement joints had been constructed at these destinations by eliminating a section from the orthotropic steel deck from the viaduct at Pylon N2 and taking away and reconstructing the Marin Abutment backwall.
