Summary
| Description |
English: Comparison of Richmond-San Rafael Bridge piers before and after reconstruction for seismic concerns.
Top photo was taken in 2003 and shows the eastern cantilever span. Pier bracing is "chevron-style" and diagonal braces come to a common central point. Bottom photo was taken in 2011 after reconstruction was complete and shows the western cantilever span. Note difference in vertical clearance between western span (180 ft) and eastern span (135 ft) which is reflected in the height of the supporting piers. Reconstructed pier bracing is "eccentric" and diagonal braces no longer come to a common central point. |
