An engineering marvel.
While it lacks the fame of its neighbor, the Golden Gate, the Oakland Bay Bridge is, if anything, a greater engineering marvel. Sporting a double deck it has a far greater span and carries more traffic daily than the Golden Gate, if with less drama. Both were completed in the mid-1930s at the height of the Great Depression and probably should be repaired right about now by putting some of those who recently lost their jobs in construction to work.
