Fabrication of Saddle for Bay Bridge East Span’s Self-Anchored Suspension Span

XKT Engineering, Vallejo, CA

August 1, 2013
Members of the media were invited yesterday to tour the steel plant in Vallejo that is fabricating key parts of the saddle system that will help secure seismic gear on the new East Span of the San Francisco-Oakland Bay Bridge. The saddle system will replace the clamping force of bolts that broke in March 2013. Visit the bolt news page for the most recent updates on the repairs and plans for opening the new East Span.
